The CD131 is a 1 inch (25.4mm) small format diaphragm compression driver. The 1 inch (25.4mm) exit is an industry standard. The CD-131 combines high BL and a very lightweight diaphragm assembly, producing high output that offers extended bandwidth and a well defined frequency response to 18 kHz. The driver has a rated low frequency response limit of 2 kHz and has a smooth response throughout its bandwidth. The CD131 features an industry standard bolt on mounting system that is ideally matched to commercially available bolt on horns.
