This RetroSound® Triax™ dual voice coil dash speaker gives you a stereo mix from your single dash speaker location. It uses a Neodymium magnet structure for high power handling in a slim-mount design. A Santoprene® surround delivers the most natural sound possible with no distortion. Dual mylar tweeters produce crisp, clear highs. This speaker can also be used in many applications in which there is a single speaker located between the rear seats.
