Features

Advanced SAW Design: Combining a specialized speaker for deep bass with a built-in amplifier to provide power, this component features Sony's patented subwoofer design. In addition, this Super Acoustically Loaded product provides bass all the way down to the lowest musical frequencies (20 Hz) from a compact cabinet.

Woofer: The SA-WM40 has a 12" long-throw woofer for deep, accurate bass.

Amplifier: The 12" long-throw woofer is powered by a 120-watt amplifier.

Surround: For a smoother response and improved durability, the woofer uses a rubber surround.

Bass Port: There is a rear-firing bass port for improved bass response.
