I recently picked up a pair of BES Planar speakers,
After listening for a month or so, I decided to replace the capacitors.
I pull off the rear cover on one, I see a sculpted panel with three separate "drivers" attached to the Panel.
The largest driver is in the middle of the panel, then two smaller drivers attached at the upper and lower corners of the panel.
The lower speaker has a coil on it, the upper small speaker has a 16UF cap
across the driver input (series?).The larger driver has the same cap configured identically.
I receive the new caps and changed them this morning, on the second speaker which I had not looked at until today, it does not have a cap on the larger driver.
I added the cap....
Can someone explain what is going on with these drivers, and x-overs?
I am now listening, they definitely sound better.
I also replaced the spring cup terminals with 3 way gold lugs a week ago.
I would appreciate any comments,I can not seem to find much info on the theory of these.
