Got my Magnepans back
I rebuilt some 1958 KLH Six's. Those were some funky metal pipe yoke speakers with their reverse rolled edges and air tight suspension. They were disassembled, crossovers were tested and rebuilt with OEM Mallory caps, suspension was redoped, new Irish linen grills and one woofer was replaced with a metal basket model salvaged from another speaker. Cabinets were refinished as well. My first attempt at either speak or cabinet refinishing. The came out great, but are not rated for my 175 wpc 1978 Hitachi SR-904 class G receiver. I use my big JBL 830's for that. Dang garage sounds better than the 7.1 in the living room!
The original woofer basket was not made of stamped metal but was a 4 dowel "teepee" setup built into the front panel that supported the coil. Talk about labor intensive as each one was made then the speaker cones were glued into the front panel. Later models utilized the metal basket speakers "without loss of performance"....? The pic with the trash bag is full of fiberglass insulation that they filled the speaker with and put a screen over the woofer so it wouldnt come into contact. the entire cabinet was air tight so as to provide the woofer with a springy suspension. even the rolled mesh suspension was latex doped and the rear terminal panel was epoxy backfilled for air-tightness. it was a ***** to open up: I had to peel the front panel away from the cabinet, just like they were built. later models used a screw in woofer for access inside. This speaker almost put them under as the labor was so intensive, both in manufacturing and in repair.
