rebuy Posted June 28, 2020 Share Posted June 28, 2020 Paper is a good, natural sounding material for Bass and Mid Drivers. In Klipsch towers of course is the Copper Cerametallic Woofers. This is also used in Subs. I understand about The Heritage Line but couldn't a Copper Cerametallic Woofer be used in those Speakers as Well? The cones are Stiffer and Less prone to Flexing than paper. Material advances in horns are being used in Mids & Tweeters, Why not Dedicated Woofers in the Heritage line? I remember reading where Infinity claimed their Ceramic Metal Matrix Diaphragm had a Much Faster response and that sound actually travelled faster off the cone than with other material they tested. So I would just assume that those principals might apply to the Klipsch Cerametallic Woofers since both are made of metals. Does sound travel faster from a Cerametallic Cone than paper or a substance like polypropylene? With all these metals being used in Squawkers & Tweeters that respond very fast, I would think a different material for woofers, that was Faster would be better.

Frzninvt Posted June 28, 2020 Share Posted June 28, 2020 Why mess with success? The original Jensen P15LL K-33's in my '62 Cornwalls say otherwise they are still going strong. The pansy material in the metal cones damages far more easily. How many dented, damaged or flexed cerametallic woofers have you seen on eBay? I have never seen a paper cone have that issue. 1 Quote Link to comment Share on other sites More sharing options...
