Feel the power of deep bass

Driving Sony's Home Theatre System and soundbar with added bass, the compact SA-SW3 wireless subwoofer immerses you even deeper into movies and music. Enjoy louder, clearer bass for a more cinematic surround sound experience.

Rich, deep bass

With 200 W² of deep bass sound from a powerful 160 mm driver, this bass reflex subwoofer boosts the impact of everything you watch and listen to. Feel the deep rumble of thunder and heavy bass beats without distortion. You’ll also hear clearer voices and extra fidelity for truly authentic soundtracks.

Omnidirectional Block Design

Sony's Home Theatre System, soundbar and optional speakers have been designed under a common Omnidirectional Block concept. The design of the SA-SW3 is a perfect match for these systems. Its sophisticated rounded edges represent a single solid block providing wide-spreading sound. The combination of rich material textures emphasizes an affinity with any living room environment.

Technologies for premium sound quality

Σ Magnetic Circuit for deep, powerful bass

Sony’s proprietary technology, the Σ (Sigma) Magnetic Circuit enables deep, powerful bass by maximizing the magnetic force that drives the voice coil. By contrast, conventionally shaped circuits let much of this magnetic force leak away.

Separated Notch Edge

Another Sony proprietary technology, Separated Notch Edge improves vertical amplitude symmetry, an essential for clear sound quality. It achieves this using concentric cuts on the edge, which help to control the stress inside and outside the edge of the diaphragm.
