Building a true 7.2 surround sound system means moving beyond the limitations of a plastic soundbar and into the world of discrete speaker channels, dedicated amplification, and object-based audio codecs like Dolby Atmos. The difference is not subtle — it’s the gap between hearing action happening around you and feeling the physical weight of an explosion in your chest. A proper 7.2 setup delivers two subwoofers for even bass distribution across the room and seven satellite channels that place dialogue, effects, and ambient sound with surgical precision.

I’m Mo Maruf — the founder and writer behind The Tools Trunk. I have spent countless hours analyzing audio hardware, decoding real customer experiences, and comparing the amplifier topologies, room-correction algorithms, and HDMI 2.1 feature sets that separate a mediocre receiver from one that will anchor your home theater for years. This guide is built on that deep market research.

Whether you are starting fresh or upgrading from a dated system, this breakdown of the best 7.2 surround sound system options will help you match the right receiver and speaker configuration to your room size, listening habits, and long-term performance expectations.

How To Choose The Best 7.2 Surround Sound System

A 7.2 system is only as good as its weakest link — the amplifier board, the room-correction software, or the speaker wire gauge you choose. Before you commit to a specific receiver or speaker bundle, you need to understand how channel count, power ratings, and subwoofer integration interact in your actual listening space.

Amplifier Power and Impedance Matching

Rated wattage per channel is rarely delivered simultaneously. A receiver that claims 100 watts per channel into 8 ohms with two channels driven may drop to 60 watts when all seven channels are active. For a 7.2 system in a medium-to-large room, look for a unit that can maintain at least 70–80 watts per channel with all channels driven into 8-ohm speakers. Lower-impedance speakers (6 ohm or 4 ohm) demand more current; receivers with robust transformer and capacitor banks handle this without distortion or thermal shutdown.

HDMI 2.1 and Gaming Features

If you connect a PlayStation 5, Xbox Series X, or a high-end PC to your system, the receiver’s HDMI 2.1 implementation determines whether your 4K/120Hz or 8K/60Hz signals pass through properly. Full-bandwidth 48 Gbps ports with VRR, ALLM, and QFT are essential for tear-free, low-latency gaming. Some receivers only support HDMI 2.1 on a subset of ports, so verify the configuration matches your setup before buying.

Room Correction and Subwoofer Integration

A 7.2 system with two subwoofers can suffer from standing waves and uneven bass response without proper digital room correction. Audyssey MultEQ XT32 (found on mid-range Denon and Marantz units) and Sony D.C.A.C. IX with 360 Spatial Sound Mapping are the two most effective algorithms for smoothing frequency response across multiple listening positions. Systems lacking room correction may sound boomy or hollow in untreated rooms.

In‑Depth Reviews

Best Overall

1. Denon AVR-X1700H 7.2 Channel AV Receiver

Audyssey MultEQHEOS Streaming

The Denon AVR-X1700H hits the sweet spot between feature depth and cost. With three dedicated 8K/60Hz and 4K/120Hz HDMI inputs, it supports VRR and ALLM for gaming, plus eARC for lossless audio return from modern TVs. The 80-watt-per-channel amplifier stage drives most bookshelf and tower speakers cleanly in medium rooms, and Audyssey MultEQ room correction tames problematic bass nodes that plague untreated spaces.

Dolby Atmos Height Virtualization is built in, so you can experience overhead effects without installing ceiling speakers. The HEOS platform gives you multi-room streaming with Spotify, Tidal, and Amazon Music HD. The on-screen quick setup guide walks you through speaker configuration and Audyssey calibration in about 20 minutes, and the color-coded binding posts reduce wiring errors.

Some users note that the Audyssey microphone cable is short for large rooms, and the interface feels dated compared to Sony’s GUI. The phono input lacks MC support for moving-coil cartridges. Still, for the price of entry into 8K-capable 7.2 surround, the AVR-X1700H delivers consistent reliability and upgrade-friendly connectivity that will serve you well into the next console generation.

What works

  • Audyssey MultEQ significantly improves bass response
  • Three HDMI 2.1 inputs support 8K/60Hz and 4K/120Hz
  • HEOS multi-room streaming is stable and easy to use
  • Phono input for turntable integration

What doesn’t

  • Calibration microphone cable is short for larger rooms
  • On-screen interface feels less polished than competitors
  • Does not support Audyssey MultEQ XT32
Performance Pick

2. Sony STR-AN1000 7.2 CH A/V Receiver

360 Spatial Sound MappingD.C.A.C. IX

Sony’s STR-AN1000 brings Digital Cinema Auto Calibration IX and 360 Spatial Sound Mapping to the mid-premium tier. The 165-watt rating into 6 ohms (1 kHz, 1ch) gives you plenty of headroom for dynamic peaks. The calibration measures multiple positions and adjusts time alignment, EQ, and crossover slopes to create a cohesive sound field — owners report hearing details in familiar movie soundtracks they had never noticed before.

The receiver supports Dolby Atmos, DTS:X, and DTS Virtual:X for when you lack height channels. Its Works with Sonos badge allows integration into existing Sonos ecosystems, and the six HDMI inputs include two outputs for zone flexibility. A few users report that Apple TV 4K Dolby Vision passthrough can be finicky, and the front display is small and hard to read from a distance. The S-Center sync feature, when paired with a compatible Sony TV, uses the TV’s speakers as a center channel to improve dialogue clarity.

This is not the best choice for dual subwoofer calibration (the room correction sometimes misreports subwoofer distance), but as a 7.2 foundation for a theater-focused space, the STR-AN1000 delivers crisp, spatially accurate audio that outpaces its price class.

What works

  • D.C.A.C. IX and 360SSM create wide, accurate soundstage
  • Six HDMI inputs with 8K/4K120 support
  • Works with Sonos integration is seamless

What doesn’t

  • No phono input for turntable users
  • Subwoofer distance calibration can be inaccurate
  • Front display is difficult to read from a distance
Premium Build

3. Sony STRAZ1000ES Premium ES 7.2 CH 8K A/V Receiver

ES Series BuildSeamless IP Control

The Sony STRAZ1000ES sits at the top of Sony’s Elite Series lineup, built with reinforced chassis construction, gold-plated binding posts, and a dual-layer bottom plate that reduces vibration. The 100-watt-per-channel into 8 ohms (2ch driven) understates its dynamic capability — in real-world 7.2 setups, it drives low-impedance speakers cleanly without thermal issues, even during extended high-volume sessions.

What sets this receiver apart is 360 Spatial Sound Mapping, which uses the calibration mic to analyze the room and create phantom height and surround speakers. In a 5.1.2 configuration, it convincingly simulates a 7.1.4 array. The unit also targets custom integrators with seamless IP control, IR pass-through, and driver-free network discovery. The included calibration microphone stand is a thoughtful touch that improves measurement consistency compared to handheld positions.

A few users note the lack of HDR10+ and QFT support despite the premium price bracket. It also runs noticeably hot even at moderate volume, requiring adequate rack or shelf ventilation. But for a dedicated theater room where audio fidelity and system integration matter more than feature count, the STRAZ1000ES is a reference-grade anchor.

What works

  • 360SSM convincingly simulates a larger speaker array
  • Robust construction with vibration-dampening chassis
  • IP control and custom integration features for smart homes

What doesn’t

  • No HDR10+ support
  • Runs hot even at moderate volumes
  • Missing QMS and QFT for some gaming use cases

4. Denon AVR-S770H 7.2 Ch Home Theater Receiver

HEOS Multi-RoomDolby Height Virtualization

The Denon AVR-S770H delivers 75 watts per channel into 7 channels (8 ohms) and includes the same HDMI 2.1 features as its more expensive sibling — 8K/60Hz and 4K/120Hz passthrough, VRR, ALLM, QFT — making it a strong candidate for console gamers on a tighter budget. HEOS multi-room streaming is embedded, supporting Spotify Connect, Tidal, and Amazon Music HD without requiring an external streamer.

Dolby Atmos Height Virtualization and DTS Virtual:X allow the receiver to create overhead effects without ceiling speakers, which is useful for apartments or homes where in-ceiling wiring is not practical. The setup process is straightforward via the guided interface and Audyssey MultEQ room correction, though the S770H uses the base MultEQ version rather than XT or XT32. Owners praise its warm, musical sound signature and the way it energizes speakers that previously sounded flat on older AVRs.

Potential buyers should be aware of occasional firmware-related volume drops and HDMI handshake issues reported by a subset of users. The remote and menu layout are dense and can feel unintuitive at first. If you can navigate these quirks, the S770H offers exceptional connectivity per dollar and remains a reliable workhorse for a mixed-use 7.2 system.

What works

  • Full HDMI 2.1 support including VRR and ALLM
  • HEOS streaming is stable and integrates popular services
  • Warm, detailed sound that pairs well with neutral speakers

What doesn’t

  • Firmware updates have caused volume and handshake issues
  • Remote and menu navigation are complex
  • Base Audyssey MultEQ lacks premium room-correction features
Slim Design

5. Marantz Cinema 70S 7.2-Ch Receiver

HDAM Discrete CircuitrySlim Chassis

The Marantz Cinema 70S stands out for its slim chassis — just over six inches tall — which fits easily into shallow AV cabinets where full-height receivers cannot. Despite its compact dimensions, it includes the company’s proprietary HDAM (Hyper Dynamic Amplifier Module) discrete circuitry, which delivers a warmer, more detailed midrange than typical chip-based amplifier stages. The 50-watt-per-channel rating (8 ohms, 2ch driven) means this receiver is best paired with high-sensitivity speakers (90 dB or higher) to achieve theater-level output in medium rooms.

It supports Dolby Atmos, DTS:X, and both Dolby Height Virtualization and DTS Virtual:X for simulated overhead effects. Audyssey MultEQ XT32 is included, which is rare at this price tier and significantly improves subwoofer integration compared to base MultEQ. The seven HDMI inputs (six rear, one front) include three 8K-capable ports, and eARC handles uncompressed Atmos from your TV. The phono input supports turntable connections, and the HEOS platform enables multi-room audio.

The lower power output may limit headroom in large rooms or with low-sensitivity floorstanding speakers. The network control app has been reported to misreport device status, and open-box units from third-party sellers sometimes arrive missing the calibration microphone. For a dedicated stereo or moderate-volume 7.2 setup in a living room, the Cinema 70S offers a level of refinement that standard Denon models cannot match.

What works

  • Audyssey MultEQ XT32 delivers excellent subwoofer integration
  • HDAM circuitry produces detailed, musical sound
  • Slim chassis fits in shallow cabinets

What doesn’t

  • 50W per channel limits headroom with insensitive speakers
  • Network control app is unreliable
  • Open-box units may lack calibration mic
Gaming Focus

6. Onkyo TX-NR5100 7.2-Channel 8K Smart AV Receiver

4K/120HzVRR and ALLM

Onkyo’s TX-NR5100 targets gamers directly with its HDMI 2.1 feature set: 4K/120Hz passthrough, VRR for tear-free visuals, ALLM for automatic low-latency mode switching, and QFT for reduced input latency. Pair it with a PlayStation 5 or Xbox Series X, and you get the full next-gen gaming experience without introducing an audio delay or frame stutter. The 7.2 amplifier stage delivers clean power into typical 8-ohm bookshelf and surround speakers.

It supports Dolby Atmos, DTS:X, and eARC for lossless audio from your TV apps. The remote is simpler than Onkyo’s older designs, with a larger front display that makes input selection and volume level easier to read from across the room. Owner feedback highlights easy setup and good overall sound quality. However, there are notable caveats: the Bluetooth implementation has sync issues with some wireless headphones, and the unit has been reported by some as being a true 7.1 receiver despite being advertised as 7.2.

Reliability reports are mixed — some units fail within two years, and the power-on sequence has been known to produce a loud pop. The spring-loaded speaker terminals for non-front channels feel less premium than the binding posts on competing Denon models. If you prioritize gaming HDMI features above long-term build quality and are comfortable with potential service needs, the TX-NR5100 provides aggressive value.

What works

  • Full HDMI 2.1 gaming suite with VRR and ALLM
  • Simple remote and larger front display
  • eARC with high-bitrate audio format support

What doesn’t

  • Advertised as 7.2 but functions as a 7.1 unit per some users
  • Bluetooth sync issues with wireless devices
  • Reports of unit failure within 18–24 months of use
Good Entry

7. Pioneer VSX-935 7.2 Channel Receiver

Dolby Atmos Height VirtualizationDual Zone Output

The Pioneer VSX-935 is a cost-effective gateway into 7.2-channel surround with Dolby Atmos Height Virtualization, which creates a simulated height layer without requiring additional speakers. It supports HDMI 2.1 with 8K/60Hz and 4K/120Hz passthrough, making it compatible with the latest gaming consoles. The dual-zone output lets you play audio in a second room from a separate source, which adds flexibility for whole-home audio on a budget.

Owner feedback indicates the sound is crisp and clear, with good movie-quality presence once you have the speaker wires properly connected. The graphical interface is somewhat dated compared to Denon’s setup wizard, and the Bluetooth implementation has been described as problematic — performing pairing and switching between devices requires navigating a multi-step menu. Some units have arrived DOA or with dead front displays, though replacements have generally been handled quickly by vendors.

At this entry level, you sacrifice room-correction sophistication — there is no Audyssey equivalent, and the manual setup is more involved. The speaker wire terminals are close together, requiring care to avoid shorts. If you are comfortable with a more hands-on configuration and want the lowest cost of admission to a 7.2 system with modern HDMI features, the VSX-935 is a viable starting point.

What works

  • Low barrier to entry for 7.2 with Dolby Atmos Height Virtualization
  • HDMI 2.1 passthrough for 8K and 4K/120 gaming
  • Dual-zone output for secondary room audio

What doesn’t

  • Bluetooth pairing workflow is cumbersome and unreliable
  • Interface and menu system look dated
  • Speaker wire terminals are closely spaced, risking shorts
Immersive Soundbar

8. Nakamichi Shockwafe Ultra 9.2.4 Channel Soundbar System

Dual 10″ SubsQuad Surround Speakers

The Nakamichi Shockwafe Ultra 9.2.4 takes a different approach to the 7.2 concept — it uses a soundbar, dual wireless 10-inch subwoofers, and four modular surround speakers to create a 360-degree sound field without requiring a traditional AVR. The SSE MAX engine processes Dolby Atmos and DTS:X signals and distributes them across nine channels (including two up-firing drivers in the bar) plus two dedicated subwoofer channels. The four surround speakers attach to dipole stands or mount on walls, and each connects via RCA cable to the nearest subwoofer — a wired backhaul that ensures stable low-latency transmission.

Owner feedback is overwhelmingly positive about the bass impact and surround precision. The dual-subwoofer configuration fills the room evenly with low-frequency energy, reducing localization issues common with single-subwoofer setups. The HDMI eARC connection handles lossless Atmos from streaming apps and Blu-ray players, and the three HDMI inputs support 4K HDR passthrough. Setup is reported to take about 45 minutes for a single person, and the included mounting hardware, cables, and detailed guide reduce guesswork.

This is not a traditional separate-component 7.2 system — you are constrained to the Nakamichi ecosystem if you want to expand or replace individual speakers. Some users note a slight static hiss from surround speakers when no audio is playing, and the included power cables can be stiff to bend into tight spaces. For anyone seeking a plug-and-play solution that rivals separates in immersion, the Shockwafe Ultra is a formidable alternative that bypasses AVR complexity entirely.

What works

  • Dual 10-inch subwoofers deliver even, room-filling bass
  • Four surround speakers create precise 360° imaging
  • HDMI eARC with 4K HDR passthrough works reliably

What doesn’t

  • Proprietary ecosystem limits future expansion options
  • Surround speakers produce faint static hiss when idle
  • Power cables are stiff and difficult to route cleanly
Clear Dialogue

9. Polk Audio MagniFi Max AX SR 7.1.2 Soundbar System

VoiceAdjust TechSDA 3D Surround

The Polk Audio MagniFi Max AX SR is a 7.1.2-channel soundbar system that bundles the main bar, a wireless 10-inch subwoofer, and two SR2 surround speakers. Polk’s patented SDA (Stereo Dimensional Array) 3D technology processes up-firing drivers and the surround speakers to create a wide, immersive soundstage with believable overhead effects from Dolby Atmos and DTS:X content. The VoiceAdjust feature boosts the integrated center channel independently, which helps dialogue remain clear even during bass-heavy action scenes.

Owners consistently praise the system’s ease of setup — no app is required for basic operation, and the soundbar auto-detects the TV remote for volume and input control. The three HDMI inputs (plus eARC) handle 4K HDR passthrough, and the wireless subwoofer paired instantly in most cases. Music streaming via Bluetooth, Apple AirPlay 2, Chromecast, and Spotify Connect is supported, and users report that music fills the house cleanly across genres.

The 10-inch subwoofer is powerful for its size but lacks the deep extension of larger 12-inch units found in dedicated systems. Up-firing speakers can sound undefined depending on ceiling height — Polk recommends flat, reflective ceilings between 8 and 10 feet tall. If you want soundbar simplicity with genuine 7.2-adjacent immersion and excellent vocal clarity, the MagniFi Max AX SR delivers with very few compromises.

What works

  • VoiceAdjust technology significantly improves dialogue clarity
  • Setup is quick and does not require a smartphone app
  • Three HDMI inputs plus eARC for flexible source connection

What doesn’t

  • Up-firing Atmos height effect is dependent on ceiling reflectivity
  • 10-inch subwoofer lacks low-end extension of larger 12-inch units
  • Recent price increases have reduced its value proposition
Atmos Starter

10. Klipsch Reference Cinema Dolby Atmos 5.1.4 System

Tractrix HornUp-firing Satellite

The Klipsch Reference Cinema system includes four satellite speakers with built-in Dolby Atmos up-firing drivers, a center channel, and a powered subwoofer. Unlike systems that only offer front height effects, the four satellites place the up-firing drivers in both the front and rear positions, creating a 5.1.4 configuration that delivers overhead effects from behind as well as in front. The Tractrix 90×90 horn tweeters produce the bright, detailed high-frequency response that Klipsch is known for, with the aluminum LTS tweeters extending the upper range without noticeable harshness.

Owners report that the satellites produce strong bass on their own, and the subwoofer adds enough low-end punch for action movies and gaming, though it lacks the deep extension of a dedicated 12-inch sub. The push-lock binding posts on the satellites require small banana plugs for a secure connection — bare wire tends to slip out more easily than on larger binding posts. The lack of speaker wire included is a recurring frustration, and users recommend 16-gauge or 14-gauge wire with banana connectors.

This system is best paired with a receiver that offers flexible crossover settings — setting the satellites to 100 Hz and the up-firing drivers to 120 Hz balanced the output well in owner tests. The plastic cabinets feel less premium than the wood-grain MDF used in Klipsch’s Reference Premiere line, but for the price of entry into 5.1.4 Atmos, the sound quality-to-cost ratio is excellent.

What works

  • Four up-firing Atmos speakers create surround height effects
  • Tractrix horn tweeters deliver clean, detailed high frequencies
  • Strong satellite bass output for a compact form factor

What doesn’t

  • No speaker wire included in the package
  • Push-lock connectors require banana plugs for secure fit
  • Subwoofer lacks the depth of larger 12-inch alternatives

11. Klipsch Reference 5.1 Dolby Atmos with R-625FA Towers

Floorstanding Towers12″ 400W Subwoofer

The Klipsch Reference 5.1 System with R-625FA floorstanding speakers is the most complete package in this guide for buyers who want a full speaker set rather than a receiver alone. The R-625FA towers incorporate built-in upward-firing Atmos elevation drivers, eliminating the need for separate height modules. The R-52C center channel ensures dialogue is crisp and centered, while the R-41M bookshelf speakers handle rear surround duties. The R-12SW 12-inch powered subwoofer, with a 400-watt peak all-digital amplifier, provides deep, tactile bass that fills even large rooms.

Klipsch’s Tractrix horn technology and LTS (Linear Travel Suspension) aluminum tweeters maintain high efficiency (90–96 dB sensitivity), meaning they produce significant output with modest amplifier power — ideal for pairing with a Denon AVR-S770H or similar mid-range receiver. Owner feedback highlights the clarity and detail the towers bring to movies, noting that the Atmos effect from the built-in elevation drivers adds a convincing third dimension to rain, helicopter, and overhead rumble scenes. The scratch-resistant textured wood-grain MDF cabinets and magnetic grilles give the system a clean, substantial look.

The supplied tower feet screws are low quality and may strip or break during assembly — many owners replace them with standard machine screws from a hardware store. The R-625FA floorstanding cabinets weigh approximately 50 pounds each, so a sturdy floor surface is required. The system is sold as a 5.1 setup, but the towers include user-configurable binding posts for bi-amping or bi-wiring if your receiver supports those features. For a dedicated theater space where you want the physical presence and dynamic impact of proper tower speakers with built-in Atmos, this is the most impactful speaker bundle available here.

What works

  • Floorstanding towers with built-in Atmos elevation drivers provide powerful, immersive output
  • 12-inch 400W subwoofer delivers deep, room-filling bass
  • High speaker sensitivity (90-96 dB) pairs well with modest receivers

What doesn’t

  • Included tower feet screws are low quality and prone to stripping
  • Heavy enclosure (50 lbs) requires secure floor placement
  • System is 5.1, so additional surround speakers may be desired for a true 7.2 experience

Hardware & Specs Guide

HDMI 2.1 Bandwidth and Gaming

A full-bandwidth 48 Gbps HDMI 2.1 port is required for uncompressed 4K/120Hz or 8K/60Hz HDR video. Receivers that implement HDMI 2.1 with less than the full 48 Gbps (often labeled as “40 Gbps”) can still pass these signals but may require chroma subsampling. VRR (Variable Refresh Rate) eliminates screen tearing by synchronizing the display’s refresh rate to the console’s frame output, while ALLM (Auto Low Latency Mode) switches the receiver into its lowest-latency processing path when a game console is detected. QMS (Quick Media Switching) and QFT (Quick Frame Transport) further reduce delay and black-screen gaps when switching between different video frame rates — these features matter most for competitive gamers using multiple source devices.

Room Correction Software

Room correction is the single most impactful feature for bass quality in a 7.2 system. Audyssey MultEQ XT32 (found on Marantz Cinema 70S and higher-end Denon models) measures at eight microphone positions and applies filters with 512x resolution to smooth frequency response across the listening area. Sony’s Digital Cinema Auto Calibration IX (D.C.A.C. IX) uses a similar multi-point measurement and adds 360 Spatial Sound Mapping, which creates phantom speakers to expand the sound field beyond the physical speaker locations. Systems without room correction — such as entry-level Pioneer and Onkyo receivers — rely entirely on manual crossover and distance settings, which often result in uneven bass response and poor subwoofer integration in untreated rooms.

FAQ

What is the difference between a 7.2 and a 5.1.2 system?
A 7.2 system has eight total channels: seven satellite channels and two subwoofer channels. A 5.1.2 system has five satellite channels, one subwoofer channel, and two overhead or up-firing height channels for Dolby Atmos. The primary difference is that 7.2 gives you two rear surround speakers for 360-degree horizontal imaging, while 5.1.2 prioritizes vertical audio. Many modern AVRs like the Denon AVR-X1700H can be configured as either 5.1.2 or 7.1.2 (or 7.2 with a second subwoofer connected via a Y-splitter or internal pre-out).
Do I need a separate amplifier for the second subwoofer in a 7.2 system?
Not necessarily. Most mid-range and premium receivers labeled as 7.2 include two subwoofer pre-outs, each carrying a line-level signal that connects directly to a powered (active) subwoofer. Each subwoofer must have its own built-in amplifier. If your receiver has only one subwoofer pre-out (common in entry-level 7.1 units), you can use a Y-splitter cable to feed the signal to two subwoofers, though you lose individual subwoofer level and distance adjustment in the room-correction software.
Can I add ceiling speakers to a 7.2 receiver that lacks dedicated height channels?
If your receiver targets a standard 7.2 configuration without Atmos height terminals (like many older or entry-level units), you cannot directly connect in-ceiling speakers as dedicated Atmos channels without sacrificing surround channels. You would need a receiver with Dolby Atmos processing and at least 9 channels (such as a 7.2.2 or 7.2.4 configuration). Some receivers offer Dolby Atmos Height Virtualization, which creates simulated overhead effects using psychoacoustic processing without dedicated height speakers — this works best with reflective ceilings between 8 and 10 feet tall.

Final Thoughts: The Verdict

For most users, the best 7.2 surround sound system winner is the Denon AVR-X1700H because it combines full HDMI 2.1 gaming support, Audyssey room correction, and HEOS multi-room streaming at a price that balances performance and value. If you want cinematic immersion and prefer a simpler all-in-one approach, the Nakamichi Shockwafe Ultra 9.2.4 delivers thunderous dual-subwoofer bass and four discrete surround speakers without AVR complexity. And for the purest theater experience with floorstanding speaker presence and built-in Atmos, the Klipsch Reference 5.1 with R-625FA towers paired with a mid-range Denon or Sony receiver will outperform almost any soundbar-based solution at driving true room-filling audio.
