I've got some speakers I've built in the early 90's and I considering rebuilding them. These are from a "kit" that MCM used to sell. Components are 55-1465 woofer, 50-650 crossover ( I can't believe they still sell these) a 1" titanium dome tweeter similar to PE 270-150 (looks the same, original was MCM brand) and a 2" textile dome tweeter MCM no longer sells. Everything mounted in a 3.5 cuft cabinet ported to about 35HZ (4" pipe, 5" long). Bass/Midbass is very strong since apparently the mids/tweeters aren't running the 95-96 db/w they were originally rated. Woofer seems to be close to 95-96 db 2.83V/m running the 8 ohm coils in parallel. They still sound fairly decent but not as good as a recent center channel project I completed (MTM using Dayton 295-305/275-070)
Are the old speakers worth rebuilding or would you just sell them and start over? I was thinking replace the tweeters w/275-070 and rebuild the crossovers. In redesigning the crossovers I'm looking at running one of the coils for low bass only and the other crossing over at 800hz. I know grilles are a no-no theses days but with an 18 month running around they are a necessary evil.
