SuperSonic uses the same space saving dual woofer, compound compression design used in our Digital Sub 600. This approach allows for a cabinet that is just half the size that would otherwise be required. We utilize two 12-inch woofers arranged in a compound compression configuration. Their combined output equals the performance of one large and incredibly powerful woofer. Auto on/off circuit with LED indicator and includes 10ft high quality gold plated interconnect cable. Internally braced, line level inputs. Stylish rounded edge cabinet design.
