STEREO/HOME THEATER SUBWOOFER
COMpACT And ACCURATE
A powerful 300 watt (900 watt peak) low-distortion, high-reliability amplifier
delivers extremely articulate bass without the need for 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 tight, well defined bass in any system.
