Infinity Kappa 9 Rebuild?

Brett...What type of amp and preamp are you using?

I am using a Sonic Frontiers Line 2 Preamp and right now a Crown XLS1500 Class D amp.  

I also have a Carver Signature Sunfire that needs some work.

I can help you with most questions that you might have about a re build. Not volunteering at this point, but I've been an avid speaker builder for 35 years and have looked kappa 9's over many times and understand them well. 

Timlub you’re my only hope!

ok so one of my Kappa 8’s is blowing up expensive amps.  After the third amp I knew....should known better after the second. 

How do i trouble shoot this?  Is it the crossover or one of the drivers or both?

This time the speaker made a squeak-like sound twice over a thirty second period, then the amp right channel died.

Also, how do I check the phase of the polydomes using the battery trick without blowing up the tweeters?
