Samson RSX118S Subwoofer passivo

It features a heavy-duty, 18" low-frequency driver with a 3" voice coil for an extended low frequency response of 35Hz–150Hz (±3dB) and can deliver a maximum SPL of 129dB. The RSX118S has two Speakon inputs wired in parallel. This enables you to expand your PA system by directly connecting an extension speaker to the RSX118S. The RSX118S's enclosure is constructed of solid 11-layer plywood and finished with a durable black, textured paint. Its black powder-coated, perforated steel grill ensures maximum protection against wear and tear. The RSX118S's rugged, roadworthy design also features a 1 3/8" pole mount receptacle, as well as two integrated carry handles for easy transportation.
