Feel the power of deep bass
Driving our HT-A9 Home Theater System and HT-A7000 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 200W1 of deep bass sound from a powerful 160mm 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 HT-A9 Home Theater System, HT-A7000 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 emphasises 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.
Easy to set up
Simply power up the SA-SW3 subwoofer and it automatically makes a wireless connection with your HT-A9 Home Theater System or HT-A7000 Soundbar. It’s quick and easy with no need for messy cables.2
