The MartinLogan Depth combines advanced acoustic engineering and innovative driver technology to deliver powerful bass reproduction with exceptional accuracy. Designed for high-end two-channel audio systems and multichannel home theaters, it brings deep, articulate bass to any listening environment.
At its core is MartinLogan's patented BalancedForce™ technology, featuring three 8-inch high-excursion aluminum cone drivers arranged in a force-canceling configuration. This innovative design minimizes cabinet vibrations by balancing the mechanical forces generated by the drivers, significantly reducing unwanted resonance and distortion.
The three drivers feature an extended-throw design that allows for substantial cone movement while maintaining precise control over low-frequency reproduction. Combined with a sophisticated servo-controlled system, the Depth delivers tight, detailed bass with impressive dynamic performance.
Powering the system is a built-in amplifier rated at 300 watts RMS and 500 watts peak. Its advanced equalization and adjustable audio controls allow users to optimize bass response according to room acoustics and personal listening preferences.
The Depth also offers flexible connectivity, including RCA line-level, LFE, and speaker-level inputs, making it compatible with a wide range of stereo amplifiers, AV receivers, and dedicated home theater processors.
With its compact, sealed cabinet and elegant design, the MartinLogan Depth provides powerful low-frequency performance without requiring excessive floor space. It is an excellent choice for listeners seeking accurate, impactful bass that integrates seamlessly with high-performance loudspeakers.
