Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Sony Bravia Theater Quad ranks #8 of 10 surround sound soundbar systems by sound quality at $2,698; the Sony Bravia Theater Bar 9 ranks #7 of 27 all-in-one soundbars by sound quality at $1,498.
Why pick the Sony Bravia Theater Quad: A fully wireless four-speaker Atmos system that sounds clean, crisp and cohesive, with clear dialogue and convincing height and surround placement. Watch for: It ships without a subwoofer, and bass lacks weight and impact, so explosions and scores feel light unless you add an optional Sony sub.
The case for the Sony Bravia Theater Bar 9: This bar spreads sound wide and high enough to feel like a much bigger system, so movies wrap around the room without rear speakers. The catch: Bass is controlled but limited, so action films lack weight until you add one of Sony’s optional subs.
Buy the Sony Bravia Theater Quad at $2,698 for a surround sound soundbar systems, or the Sony Bravia Theater Bar 9 at $1,498 for a all-in-one soundbars instead.
