    Product Description

    The Earthquake Sound CP8 Couch Potato is a down-firing powered 8-inch compact special applications subwoofer designed to deliver deep and precise bass right at your sitting position. It features a premium 8-inch long-throw woofer with a built-in high-efficiency class AB amplifier that produces up to 300 watts of peak power. The woofer features a durable, lightweight pressed paper cone with a wide Santoprene surround and a 2-inch voice coil that ensures low distortion and long-lasting performance. The CP8 amplifier is equipped with a variable crossover and phase control to adjust the sound to your listening preferences. The crossover allows you to set the subwoofer's frequency range from 40Hz to 120Hz, while the phase control lets you align the subwoofer with your main speakers for optimal sound quality. This subwoofer is easy to install and connect with any speaker system; whether watching movies, listening to music, or playing games, the CP8 will transform your listening experience with its dynamic and immersive sound. Because the CP8 is only 7 inches in height, it allows for unique placement possibilities, such as underneath or behind sofas, beds, and other furniture. It can also be placed on its side and in between the back of the couch and the wall making it a versatile option for home theater systems. By placing the subwoofer closer to your sitting position, the bass is faster, more powerful, and carries massive subharmonic vibrations that all home theater enthusiasts can appreciate. A sizeable 3-inch port at the long end of the enclosure lets you direct bass out from under a couch or bed without losing precision and energy, which provides a high output of the lower frequencies. It gives the robust woofer optimal working conditions, resulting in a strong and accurate bass response. With incredible versatility and a slim form factor in mind, the low-profile CP8 offers flexibility and concealment without sacrificing precious floor space. It will quickly become an indispensable fixture for your home theater system, allowing you to add outstanding bass to unused space. If you are looking for a subwoofer that delivers high performance, low distortion and is placement friendly, look no further than the CP8 Couch Potato by Earthquake Sound.

    Wanna feel like you're IN the movie?
    I have limited space in my 10'x13' room. I have a 10" Martin Logan sub which is great, but I wanted to FEEL the bass while watching movies. I bought this CP8 with little expections, and after setting it up with a calibration, this is what I hoped it would be.. You feel like you're in the movie. Fast and Furious was awesome with all those cars.. But I still wanted more.... lol. So I bought another one.. Yep, duel CP8's. It's like DBOX without the seat moving around. I can't watch a movie without it. I'm lucky that my seating is a futon, cuz these fit perfect. I highly recommend the CP8.. It's NOT *room shaker* but it ROCKS the seats.. Best investment for a small room...
