Overview
Sony's SA-SW3 adds dedicated low end to an existing setup as a floor-standing subwoofer rated at 200 watts and connected via RCA. It measures 15.88 x 8 x 15.13 in and weighs 10.5 lb.
As a dedicated subwoofer rather than a full range speaker, its job is limited to low frequency output, added to an existing stereo or home theater setup through its RCA input. The floor-standing design and 10.5 lb weight point to a unit meant to sit on the floor rather than mount or shelf-sit.

- 15.88 x 8 x 15.13 in, 10.5 lb
Who it's for
Fits buyers adding dedicated bass to an existing RCA-equipped receiver or amplifier. Not a standalone speaker and not for anyone needing a wireless connection.
Pros and cons
- 200 watt rated output for added bass
- Simple RCA connection to an existing system
- Wired RCA only, no wireless option listed
- Requires floor space, no compact mounting listed
Performance notes
A 200 watt amplifier drives the low-frequency output here, and the RCA connection means it draws its signal from a receiver or amplifier's subwoofer output rather than working as a standalone unit. Floor-standing mounting and the 10.5 lb weight keep it stable once placed.
