Today I got a pair of used cabinets with crossovers of Shahinian Obelisk speakers that I would like to rebuild with new drivers, passive radiators, and crossovers.
I thought the obelisks were an interesting speaker back in the 80s but much too expensive for me back then. Shahinian has gone through several revs through the years with differing woofers/passive radiators, tweeters and mid-domes on top in 3 way versions of the obelisk.
This is a very old version which had 3 tweeters, an 8" woofer and a 10" passive radiator on the back.
Newer versions added a driver or two on the back face of the pyramid top which this doesn't have.
Internally there's a board diagonally across dividing the box into a transmission line that folds
at the pyramid top.
The internal cross over is very simple with a fuse, one 6.8uf film capacitor and an inductor which doesn't
seem to have any obvious markings on it. The three tweeters were connected in parallel.
I would be interested in opinions of what to stuff in these. I have no problems soldering, etc, but am a little woodworking challenged, though I can probably ask someone local for assistance if necessary.
