Sanway RS18 uses two 18 long excursion drivers in a birch plywood cabinet to extend Low profile, high output system. The new technology permitting acoustic distance from rear to front sections to always increase as frequency decreases. With frequency response down to 30Hz, sensitivity 105dB, the rear and front portions are effectively summed over the entire subwoofer bandwidth, allowing an average gain of 5 dB from the front direction and being canceled at the rear. The RS18 is versatile for installations and touring requirements where large format sub-bass cabinets are required.
