The SDA-500 is a warm sounding, cool-to-the-touch, all-digital subwoofer amplifie. It is designed for subwoofers that require a lot of power.
The SDA-500 is available as an upgrade with all of our powered subwoofers. Its slim design allows it to be placed near and even underneath many subwoofers. But unlike subwoofers with built-in amplifiers, the SDA-500 can be placed instead with your other AV equipment requiring only standard speaker cable to connect to your subwoofer.
