What does 1000W of power mean to you? It means having a subwoofer that delivers rump-shaking bass night after night. It means getting class-leading power and output. To accomplish this, the SRM1801 features Class-D Fast Recovery™ amplification. Class-D amps are more efficient and lightweight, with far less waste heat produced versus competing designs. Fast Recovery means you can occasionally push into clipping without a ton of nasty distortion. So, power is no problem... but how does it sound? The SRM1801 benefits from built-in Active electronics, like a precision crossover and tuning filters for accurate bass response. Some subwoofers have decent power, but when you listen, everything sounds loose and flabby. The SRM1801 delivers professional low end that you can feel...custom tuned to be tight and punchy.

Well, the SRM1801 offers class-leading power in its price range. You need it to go low...body vibrating low. The SRM1801 has a high-output 18" woofer that can be felt from across the room. It's got to be easy to move and built to last. The SRM1801 incorporates features that make it lighter and more portable than the competition.
