What customers say
Enthusiasts highly praise the MartinLogan Depth subwoofer for its accuracy and musicality. Customers consistently report deep, impactful bass that remains remarkably tight and articulate, avoiding muddy sound. A key strength is its seamless integration into high-fidelity systems, often exceeding expectations given its compact size. Build quality reflects its premium positioning. While performance generally justifies the investment, the high price places it firmly in the luxury category. Achieving optimal results sometimes requires careful calibration. Overall, this unit is viewed as a top-tier solution for those seeking reference level bass performance in a manageable package.
Know before you buy
The BalancedForce array uses three 8-inch drivers positioned to cancel out opposing forces. This design significantly reduces cabinet vibration and resonance, resulting in tighter, more accurate bass rather than the muddy output often found in smaller subwoofers.
The Depth is designed to excel at both. Its servo-control technology ensures the precision required for high-fidelity stereo music, while its 500W peak power provides the impact and depth needed for immersive movie soundtracks.
The subwoofer measures approximately 16.25 inches high, 16.6 inches wide, and 16.15 inches deep. It weighs 65 pounds, so ensure your floor or stand can support its weight and that you have adequate clearance in your room.
Yes, the Depth includes speaker-level inputs, allowing you to connect it directly to the speaker terminals of an amplifier or receiver that does not have a dedicated RCA subwoofer output.
The unit offers flexible low-pass crossover settings ranging from 30 Hz to 80 Hz, allowing you to fine-tune the integration between the subwoofer and your main speakers. It also features a bass control adjustment of ± 12 dB at 25 Hz to help you tailor the output to your room's acoustics.
