Martin Logan Grotto 15 Subwoofer in Gloss Black

The original Grotto subwoofer set a standard for clean, powerful bass in a compact, decor-friendly design. The all-new Grotto series carries on that legacy with advanced amplification, precision drivers, and ARC Genesis Room Correction; delivering deep, controlled, and impactful bass from an elegantly understated form. Featuring MartinLogan's largest, most powerful hybrid woofer to date, Grotto 15 uses dual 15-inch passive radiators to enhance the low frequency output of its powerful, active 15-inch aluminum cone woofer. This high-output woofer is driven by robust amplification and a best-in-class 64-bit DSP engine to extract maximum performance. Grotto 15 offers a wide range of connectivity options including XLR, RCA, speaker level, and built-in wireless, plus the added convenience of the MartinLogan subwoofer control app. With support for the award-winning anthem room correction(ARC) system, Grotto 15 can also be expertly tuned in a matter of minutes using the optional ARC Calibration Kit.
