Magneplanar speakers

My speaker cables are very short (about 300 mm) because I have the Propius amps very close to the left and right floor standing speakers. I made a four way plait with Spatia hookup wire and connected one pair to each plug. For bi-wire I fitted two red and two black at the speaker end. The Magnepan terminals are at floor level which helps.

Back to my Magneplanars...

They have a steel panel at the front with vertical lines of holes between the fixed magnets. Just behind them is a stretched mylar film with parallel aluminium (light weight) wires that the amplifier current runs through causing the mylar to move back and forth. This photo is from rear and shows the mylar with the wires glued to it (or 'laminated'). The ends go to the terminals at the top. In this early Magnepan the two sections are wired in series and the crossover elements provide a bypass for the full range signal with the inductor in parallel with the thin treble wiring on the left and capacitor in parallel with the wires on the large bass/mid panel.

I made the new covers or 'socks' by buying some acoustically transparent cloth, turning it inside out and machine sewing seams top and side. Turn it the right way round and slide it over the speaker panel which has grooves cut into the mdf edges.

Now the terminals and crossover...

You can see the four terminals at the top, just under the tea towel I used to protect the mylar and laminated thin wires from the hot solder.  The gold coloured panel has the original terminals which I contact cleaned and the fuse designed to protect the tweeter's thinner wire.

I replaced the original red, blue, and black wires above with Spatia hookup wire and ran similar length wires out to the newish capacitor I fitted instead of the small original component...
