The LX-Series takes traditional folded horn subwoofers to the next level. They are built to withstand the abuse of the road and are backed by a lifetime cabinet construction warranty. A newly designed internal compression chamber provides intense, clean and controlled bass. At the heart of the LX-Series is the new B-52 18-200L subwoofer with a cast-aluminum frame, a massive 200 oz magnet and an innovative 4” dual-layered, tempered aluminum voice coil.
