Active Subwoofers

Seaton Sound SubMersive HPi+ Subwoofer Review

Seaton Sound builds subwoofers primarily for custom installations. As such, they do not have a lot of knobs, switches, and dials on the amplifier panel. What they do have is great sound - punchy and deep - with the capability of having a 6,000 watt Class D amplifier driving the main enclosure and an additional passive enclosure. You can imagine the results.
