I've been building speakers for 30+ years. I salvaged some amt tweeters out of a pair of mismatched Martin Logan speakers given to me (3" & 4" woofers.)
I paired them with 6.5" Hivi woofers. I built xovers out of what I had on hand. 2nd order 4k hz on the woofer, same slope but 4.5k on the tweets.
I installed them in homemade boxes I got at a thrift store. I had to pad the tweeters but otherwise, fantastic. The pushed a pair of JPWs into the closet.
All fine except these cabinets were too small.
More thrifting and I found a pair the right size. Q of .7, perfect.
After adding bracing, altering the tweeter hole and painting the front baffle I installed the drivers and...wtf! No bass.
I was using a sub and 100uF on the input I was at a loss. I listened to both sides of a folk album, gave up, went to bed.
In the light of day, obviously I hooked up the xover backwards. How those tweeters didn't burn out, no clue. It's been 5 or 6 weeks and they're fine.
I've since turned the sub down and no caps on the speakers. I guess I'll sell the JPWs, the best speakers I ever bought.
