About the Depth i
The MartinLogan Depth i is a high-performance powered subwoofer featuring innovative BalancedForce TriLinear technology with three 8-inch (20.3 cm) high-excursion aluminum cone drivers arranged 120 degrees apart to eliminate cabinet resonance and deliver tight, accurate bass with electrostatic-like detail. Designed for both high-end stereo and home theater, it uses sophisticated servo-control and a 350W amplifier for low distortion and purity. It is compact (40% smaller than the Descent i) yet extends to 20 Hz, blending seamlessly with electrostatic or cone speakers. Controls include ±10 dB level at 25 Hz, low-pass filter (30-80 Hz), high-pass filter (bypass/40/70 Hz), phase, and auto/standby power. Inputs: left/right RCA line level, RCA LFE, speaker level. Discontinued model with price listed as when discontinued.
