The LX-18V3 takes the traditional folded horn design to the next level. The made in the U.S.A. cabinet is built to withstand the abuse of the road and is backed by a lifetime cabinet construction warranty. A specially-designed internal compression chamber provides intense, clean and controlled bass. At the heart of the LX-18V3 is the new B-52 18-220X with a cast-aluminum frame, massive 220 oz magnet, double spider anti-rocking surround and innovative 4” dual-layered, tempered voice coil.
