The Rock Shaker 10 is a powered 10-inch subwoofer that may be used in a variety of settings, including a home theater or recording studio.
This device combines high grade components from the ground up and produces clean sound with tight and thumpy bass you can definitely feel.
The MDF used to construct the enclosure is of the highest quality, allowing for excellent sound reproduction. For the best possible sound quality, we pair a woofer and enclosure with a powerful amplifier of the class "D" variety that was designed specifically for them. We tested the rear firing port and decided it gives the best bass response where you obtain optimal reflection that will disseminate the sound across the space.
Top-notch features include a foam surround, Y30-grade magnet, and 4-layer voice coil in the woofer.
Our subwoofer may be used with a wide variety of systems thanks to its RCA connectors and high-level speaker inputs and outputs.
