Sony SA-SW5 Wireless Subwoofer, 300 W, Black

The Sony SA-SW5 is a dedicated subwoofer designed to expand a home cinema setup. This 1-channel system functions as an add-on unit for compatible soundbars, providing low-frequency effects for television and music. With an RMS power output of 300 W, it provides enough headroom for high-volume, distortion-free audio. Instead of using speaker wires, the module connects wirelessly to the main receiver. It focuses exclusively on the low-end spectrum, and the absence of physical signal cables simplifies installation and placement.

The black cabinet measures 277 mm wide, 409 mm high, and 422 mm deep. Weighing 13 kg, the heavy enclosure helps suppress vibrations during action-heavy scenes. Because it relies on a dedicated link to a host soundbar, the unit does not have standalone Bluetooth or Wi-Fi support, and audio cannot be cast to it directly from a mobile device. The design fits easily beside media consoles, allowing the module to integrate into a multi-channel system.

• 180 mm woofer: A forward-firing driver that reproduces low, impactful frequencies.
• Passive radiator arrangement: Improves low-end extension and acoustic efficiency without the port noise associated with vented enclosures.
• S-Master digital amplifier: Processes audio signals efficiently to maintain high output while keeping internal circuitry cool.
• Built-in LED indicators: Provides visual confirmation of the power status and pairing connection with the soundbar.
• AC power cord included: Connects directly to the mains for continuous operation without requiring an external power brick.
