Rich, Deep Bass

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

Our 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.

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

Easy to Set Up

Simply power up the SA-SW3 subwoofer and it automatically makes a wireless connection with your Home Theatre System or soundbar. It’s quick and easy with no need for messy cables.

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.
