If you do resurrect, please please please put a tweeter in them that was actually designed to be used with a first order crossover. I had a pair of scvVI’s , huge monsters that weighed around 500lb each, that blew tweeters like there was no tomorrow. When old John was around, he actually sent me 5 matched pairs. These tweeters were meant to be used with 2nd order crossovers or above, certainly not 1st. They just received far too much upper mid to play at higher levels. Their sound was awesome though, I’d still have them today if their power handling was realistic for their size. I had the same trouble with their centre channel (ccv?), and also scvII’s used as surrounds in a 5.1 av system. Once you cut into all that thick felt covering the tweeter surrounds, I became an expert at tweeter installation, even though the centre channel was 8’ off the ground!
