MartinLogan Grotto Compact servo-controlled Subwoofer

PREOWNED - FULLY TESTED - INCLUDES ORIGINAL SPIKES, POWER CORD, GRILLE

WORKS GREAT - SOME SCUFFS/SCRATCHES ON CABINET, CHIPPED ON BOTTOM, HOLE IN GRILLE (REFER TO IMAGES)

The world's most affordable servo-controlled subwoofer, Grotto proves that a precise, compact subwoofer can have the heart of a beast.
Grotto combines explosive bass power with servo-controlled accuracy and precision in a surprisingly compact cabinet at a perhaps even more surprisingly affordable price. At its core are the same high-resolution 10-inch aluminum-cone driver used in our flagship Descent subwoofer and a proprietary advanced-design amplifier. Easy to set up and sporting an attractive contemporary look, Grotto integrates comfortably into any room and system.
