Dave A Posted July 14, 2018 Share Posted July 14, 2018 OK I dug into the four KP456 horns from a guy in Boulder Co and finding really ugly stuff. Two work and two did not. In the one the edge of the diaphragm is cracked and on the other the phase plug broke into two pieces and both became loose and the diaphragm was a pile of Ti flakes. Taking the diaphragm off of the others it appears the phase plug is glued as it is in there solidly and looks like glue is the only way. Is this correct? Also what exactly is the difference between the 8ohm and 16ohm diaphragms practically speaking in relation to the crossover? There was only one crossover made for these so I assume both will work fine just as long a they are matched in ohms to each other. This leads me to asking also if anyone has any of these drivers to sell and what would you want for them. Quote Link to comment Share on other sites More sharing options...
rockhound Posted July 14, 2018 Share Posted July 14, 2018 Dave - Sorry I cant answer your questions about the diaphrams and wot not but I may sell the horn/drivers from a pair of my 456's in the near future. I will let you know if I decide to. Quote Link to comment Share on other sites More sharing options...
