Description
Martin Logan's all new Grotto series carries on the original Grotto's legacy and takes it to the next level. Its subtle appearance belies the raw performance concealed beneath its grilles. The Grotto series subwoofers offer a unique combination of understated, minimalist styling and impressively powerful, yet articulate performance. Utilizing MartinLogan’s largest, and most powerful Hybrid Woofer Systems to date, Grotto 12 and Grotto 15 pack an incredible feature list and massive power into a classy, room friendly design, making them an ideal choice for those looking for a high performance, high output subwoofer that won’t look out of place.
The Hybrid Woofer System used in the Grotto series pairs either a 12" or 15" active aluminum woofer with two equally sized, custom-designed aluminum passive radiators. This driver layout provides the massive surface area necessary to achieve the increased output and lower distortion of a ported design while maintaining the more compact sizing and tighter bass typically associated with a sealed design. Solid bass performance is a critical component of any audio system, and helps provide visceral impact to your entertainment. Both Grotto models feature integrated anti-vibration feet to improve bass performance by reducing floor and wall vibrations. By dramatically reducing the energy transfer between the subwoofer and the floor, unwanted room rattles and buzzes are removed, leaving tighter, cleaner bass and improved system clarity and dynamics. As a less intrusive alternative to acoustic room treatments, the integrated anti-vibration feet can also aid in minimizing noise complaints by reducing vibration transfer into adjoining rooms. Out of the box, these robust anti-vibration feet are safe for all flooring types, and optional carpet spikes are included to further improve performance on carpeted floors.
