Compact and Accurate
A powerful 300 watt (900 watt peak) low-distortion, high-reliability amplifier gives Grotto i extremely articulate bass without need of exaggerated amplifier power ratings or transient-blurring ported or passive radiator enclosures common to many modern subwoofers. A proprietary servo system further ensures that output from Grotto i's 10-inch high-resolution aluminum cone woofer is dramatically free of distortion and provides a faithful replica of the audio input signal.

Good Sub
This sub is awesome!!! Worth every penny. Went from a bose system to this and its night and day. Wouldn’t be surprised if the foundation of my house has moved.
AWESOME SUB
The subwoofer sounds great. The bass is smooth and tight. I wish I would have bought two of them at the time of purchase. I may add another one later. I also like the cabinet design.
What Subwoofer ??
I used to hate subwoofers until I paired the Grotto with my Magnepans. They integrate very well and are fast enough to keep up with the Maggies.
