The 15-X-SS Champion is our top of the line, no-compromise 2-way trap enclosure. It features a 4" voice coil Neodymium 15" low frequency transducer with a 600 W RMS power handling. This powerfully crisp sounding woofer is matched by a 4" voice coil Neodymium 2" compression driver for unparalleled reproduction of the mid range and high frequency spectrum. This knockout combination results in the finest vocal & instrument reproduction we build in an enclosure of this size. The specifications speak for the Champion.
