Compact and Accurate

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.
