Well, I just went ahead and recapped both of them, one with .01 Wima bypass caps on the squawkers and tweeters, the other with .01 Vishays. I found a pair of NOS K-52-H's to replace the mismatched K-52-K and K-55-M. I also got a pair of Crites tweeters to replace the mismatched and blown K-77-M and T35 tweeters.
First of all, They sound great. Oh hell yeah... Effortless from the bass up through midrange. Well articulated but not fussy. It's too early to tell if there is a difference between the two with their different bypass caps, That will take a few weeks of listening with a well sorted amp.
I also discovered after I sealed up the cabinets that I have the squawkers wired up out of phase. I will, of course change them, but in the mean time what difference is this making to my ears?
Also, is there some where on this forum where it would be appropriate to post about trading my mismatched leftover drivers?
