About the Sony SA-SW3 200W Wireless Subwoofer

The Sony SA-SW3 is a 200W wireless subwoofer built to add low-end punch to Sony's BRAVIA Theatre soundbars and home theater setups. It pairs over a wireless link, so there are no speaker cables to run across the room. A single 160mm front-firing driver in a bass-reflex cabinet handles the bass. It is a one-job add-on, not a standalone speaker, and it is not weatherproof or portable.

Best forOwners of compatible Sony soundbars wanting deeper bassSmall to mid-size living rooms and home theatersPeople who want wireless setup without running cablesMovie and game soundtracks that need low-end impact

Questions and answers

Which Sony soundbars does the SA-SW3 work with?
It pairs wirelessly with select Sony BRAVIA Theatre and soundbar models that support the SA-SW3. Check your soundbar's accessory list before buying, since it will not work with other brands.
Does it need a cable to the soundbar?
No. It connects wirelessly to a compatible Sony soundbar, so you only need to plug it into power.
Is 200W enough for a large room?
It is enough for most small and mid-size rooms. In a very large or open space, a single 160mm driver may run out of headroom.
Can I use it outdoors or in a bathroom?
No. It is not waterproof and is designed for indoor home theater use.
Does it have its own app or streaming?
No. It has no independent streaming or app control; bass settings are managed through the paired Sony soundbar.
What is in the box?
You get the subwoofer and a power cord. No speaker cable is needed because the connection is wireless.
