Your Ride, Our Sound. Even Sweeter.

That rear deck is aching for thunderous loudspeakers like the DXi691 6x9-inch 3-way loudspeakers, featuring both a 25mm liquid-cooled silk/polymer dome tweeter and a 19mm super aluminum dome tweeter. Want more performance but don’t want to go the component route? Choose the DXi691 3-way. You get a woofer and tweeter, plus a dedicated midrange driver for the absolutely crucial mid-frequencies, which can create more uniform sound overall.

Klippel optimized components for consistent, distortion-free sound.
