SUB221-C

SUB221-C 2 x 21" Cardioid Subwoofer

The SUB221-C is a high power compact cardioid subwoofer cabinet designed to allow an high attenuation between front & rear faces. Equipped with two 21-inch ND drivers. One driver is placed in a front direct radiating position and a second in a rear sidefacing position to create a bandpass configuration.
This system is capable of accommodating up to 6'00W of power continuously. With a cut-off frequency of 30 Hz, the SUB221-C is made for applications where the reproduction of sub frequencies is important and where you have to minimize the rear emission in order to get an higher sound quality and avoid resonances and reflections.
