For a bottom end boost to your compatible* Sony soundbar or home cinema system, you need the Sony SA-SW3 wireless subwoofer.

Easy set-up
If you’ve got a compatible* 2021 Sony soundbar or home cinema system but feel it’s just lacking in the bass department, then here’s your answer. Designed to effortlessly, wirelessly connect to the system, the SA-SW3 is ready in no time to add a new dimension in bass.

Punchy bass
With 200 watts of oomph available, you can soon feel the difference the SA-SW3 makes. Sony’s proprietary Sigma Magnetic Circuitry technology maximises the magnetic force, giving you bass that’s not just deep but powerful and sustained.

Clean sound
Another Sony proprietary technology, Separated Notch Edge, uses an innovative woofer surround to reduce cone distortion. Less distortion means a cleaner, punchier sound, without the excessive ‘boom’ and wallow that can afflict some subwoofers.

Compact Premium Omnidirectional Block Design
Designed to harmoniously blend with the soundbar and optional SA-RS35 rear speakers, the Omnidirectional Block Design gives a unifying style to the whole system. The rounded edges don’t just look sleek, they help promote a wide spread of sound, too. Smaller than the SA-SW5 model, the SW3 makes the ideal choice for smaller rooms and tighter spaces.

Introduce that ‘edge of seat’ cinema thrill to your system, with the Sony SA-SW3.

*Please note, this subwoofer is currently only compatible with Sony’s Dolby Atmos/DTS:X 2021 home cinema line-up, including the HT-A7000 and HT-A9 speaker package.

Rated 3 out of 5 by from Sony Products and Service Reasonable performance but disappointing as it tends to overwhelm output and clarity of the soundbar.

Rated 5 out of 5 by from It does what it is supposed to do I required a subwoofer to be used with a Sony Soundbar. On line research and visit to John Lewis identified the subwoofer I needed. The subwoofer was purchased from Richer Sounds as it was £100 cheaper than John Lewis and a six year warranty was available at 10% of the purchase price which was refundable after six years if not used

Rated 5 out of 5 by from Being used with the A7000 Sound Bar The A7000 Sound Bar is great, this wireless subwoofer with SA-RS5 rear speakers makes the whole system sound awesome.
Date published: 2023-06-22
Rated 5 out of 5 by from Great bass I have the SA-SW3 in a small boxy room and at first I thought it was a bit boomy. After a little playing around with positioning (ended up moving about 6" back along the wall) and re-optimization the sound is brilliant. A great addition to the HT-A7000 sound bar and SA-RS5 surrounds.
