Detailed review
Power and inputs are where the Z906 still feels relevant years after launch. Five hundred watts of continuous power with the ability to deliver peaks under dynamic passages gives action scenes physical weight without asking small drivers to do subwoofer work. The control console and wireless remote let you switch among up to six devices—computer, TV, game console, music player, and more—through digital optical, digital coaxial, RCA, and six-channel direct paths. That flexibility makes it a media-room hub rather than a TV accessory only.
Setup is honest wired work. Each satellite connects to the subwoofer and console chain, which means you will route speaker wire along baseboards or through cable channels to rear corners. Wall-mountable satellites help when floor space is tight, but you still need to think about wire length and tripping hazards. The payoff is imaging: when a game or movie sends effects to the rear channels, you hear them from physical locations behind you instead of algorithmic widening from a single bar.
Sonically, expect assertive bass, clear center-weighted dialogue when content is mixed correctly, and the kind of dynamic swings THX-branded systems aim for. The Z906 will not decode Dolby Atmos height objects like the Sony System 6, and it will not pair with your LG TV remote through WOW Interface. What it does is play Dolby Digital and DTS soundtracks the way studios intended on a stable wired 5.1 bed—something virtual soundbars struggle to replicate in the same seat-to-seat consistency.
Compared with Sony's wireless package, Logitech asks for more cable discipline and furniture clearance yet rewards that effort with input switching depth and a proven long-term track record. Compared with ULTIMEA and budget 5.1 soundbar kits, Logitech's satellites are smaller but the THX tuning and console-driven control feel more mature for mixed PC and home theater duty. Compared with the Bose TV Speaker or detachable smart TV bar, it is an entirely different category: those products fix thin TV sound quickly, while the Z906 builds a surround stage.
Choose the Z906 if you want a reference wired 5.1 stack for a PC desk, gaming lounge, or media room where optical and analog inputs cover your sources. Skip it if you need HDMI ARC simplicity, wireless rears, or a slim bar under a wall-mounted TV. For surround sound speakers that prioritize discrete channels and multi-device control over living-room minimalism, it remains the pack's best true 5.1 answer.
Who it is for
PC gamers, console players at a dedicated station, and media-room builders who want THX-branded 5.1 without an AV receiver. Strong when you already have optical or analog outputs from TV, console, or sound card.
Setup notes
Label each satellite channel before wiring. Keep rear speakers at ear height when possible and angle them toward the main seat. Place the subwoofer where bass feels even, not only loudest, and use the console to set per-input levels once rather than adjusting nightly.
Versus soundbar surround packages
Sony, LG, and ULTIMEA win on wireless rears and HDMI ARC TV integration. Logitech wins when you need six switched inputs, wall-mountable wired satellites, and THX voicing for a fixed media station.
