Product Description

Grotto i deploys the full array of MartinLogan's advanced subwoofer technologies to achieve deep, rich, satisfying bass while preserving electrostatic-like accuracy and detail. Its advanced low-distortion switching amplifier and sophisticated servo control system extract the very best possible performance from Grotto i's high-resolution 10-inch aluminum-cone driver. 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. An optimized selection of connections and controls allow connection of both 2-channel stereo music and multi-channel home theater while allowing each connection to have unique crossover and level settings. LFE input effectively uses no low-pass filter, leaving crossover control to the processor. Left/right line level and speaker level inputs integrate six discrete audiophile grade low-pass filters between 30-80Hz allowing a different level and crossover point when playing back two channel music. RCA output allows multiple Grotto i subwoofers to operate in series. A unique 25Hz level control allows adjustment of system response by ±10dB to eliminate low-frequency build-up or suck-out at a room's most problematic bass frequency. ETC spikes couple the sub directly to the floor, minimizing lost energy and allowing tight, well defined bass in any system.
