$600 for BOTH Used B-52 LX18V3 18in Folded Horn 1000W Unpowered Subwoofers

This powerful folded-horn subwoofer cranks out devastating, long-throw bass on a budget and still manages to be quite portable. The B-52 LX-18EV3 is ideal for live sound and music replay applications and delivers more low-end thunder than you'll know what to do with. This sub's cabinet is fitted with B-52's 18-220X 1000W subwoofer, which provides high-power handling, great efficiency, very low distortion, and accurate sound reproduction. The American-made cabinet features 7-layer 3/4" plywood construction, reinforced internal bracings, and is finished with impact-forgiving black carpet, which shows a lot of wear and tear that doesn't affect functionality, and has 4" heavy-duty casters.
