MartinLogan Grotto 12 Subwoofer

The original Grotto subwoofer set a standard for clean, powerful bass in a compact, décor-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. With larger drivers and more power than its smaller siblings, the Abyss 8 and 10, the Grotto 12’s Hybrid Woofer System uses dual 12-inch passive radiators to enhance the low frequency output of its powerful, active 12-inch aluminum cone woofer. This high-output woofer system is driven by robust amplification and a best-in-class 64-bit DSP Engine to extract maximum performance. Grotto 12 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 12 can also be expertly tuned in a matter of minutes using the optional ARC Calibration Kit.
