Earthquake CP-8 Couch Potato – 300W Peak, 8-Inch Slim Subwoofer

Compact power for near-seat bass

Experience deep, precise bass at the listening position with the Earthquake Sound CP-8 Couch Potato. This compact, down-firing 8-inch subwoofer pairs a robust long-throw woofer with a built-in high-efficiency class AB amplifier, delivering up to 300 watts of peak power. The result is bass that feels fast and punchy, even when the listening seat is just a few feet away. The driver uses a lightweight pressed paper cone, reinforced by a wide Santoprene surround and a 2-inch voice coil to help reduce distortion while sustaining clean, low-end energy across a wide range. You’ll notice how the bass integrates with dialogue in films and musical transients in songs, all without overpowering the rest of the spectrum.

It’s designed to be placed where space is precious. At just 7 inches tall, it can hide under a sofa, stand on its side between the couch and wall, or tuck behind furniture. A large 3-inch port helps project bass outward from under seating while preserving control and clarity at lower frequencies. With a variable crossover from 40 Hz to 120 Hz and a 0–180-degree phase control, you can fine-tune the blend with your main speakers for a cohesive, immersive soundstage. The CP-8 also offers Auto/On/Off sensing and both low-level and high-level inputs and outputs for flexible connections, so you can pair it with a wide range of amplifiers and speaker configurations.
