Grund Audio Design’s LC-2SA, LC-5SA and LC-8SA subwoofers are all powered systems that incorporate a 2.1 amplifier designed to drive both the subwoofers and stereo satellite LC column-array loudspeakers. The LC-2SA subwoofer features a 1,200-watt Class D amplifier, whereas the LC-5SA and the LC-8SA employ 1,600- and 1,800-watt Class D amplifiers, respectively. All three subwoofers include onboard DSP capabilities that provide programmable loudspeaker-management settings for optimizing the column array/subwoofer combination for a variety of environments. The LC-2SA uses a 12-inch LF transducer, whereas the LC-5SA has a 15-inch transducer and the LC-8SA offers an 18-inch transducer. For details, visit grundaudio.com or booth #6332.
