Beyma CP25 Tweeter

The perfect tweeter to upgrade the Khorn and Belle Klipsch speakers.  They are a big improvement over the stock K77 tweeters in every way, and offer a lush, full, rich sound that integrates perfectly with the V-TracII midrange horns.

The Beyma CP25 tweeters sold by Volti Audio are selected and modified before being sent to our customers.   Approximately 20% of the CP25's that we get are rejected and sent back to the distributor because they don't meet our quality standards.  The remaining ones are modified by us to provide a smoother response.  So when you buy Beyma CP25 tweeters from Volti Audio, you are getting the very best sounding CP25's there are.
