I'm at a bit of a loss here and would love any kind of feedback you might have.
I bought two pairs of Monitor 7Bs. One pair sounded fine; one sounded a bit thin in the low mids and the upper bass frequencies. I gave the good pair to my friend and kept the other pair thinking a recap would take care of the problem.
The pair I have has very pronounced treble and high-mids. (I should mention both speakers sound identical.) There are really low lows that the passive radiator seems to grab, but there is definitely something missing in the frequency spectrum.
I recapped with Sonicaps and put in Mills resistors and it didn't fix the issue.
The seals seem fine. I hold in the passive radiator and the mid-driver actually doesn't sink at all.
The magnets seem to be fine and I don't see any evidence of driver damage.
The wiring seems to be ok from what I can see. The black/positive wires are hooked up to the the red-dotted terminals. (The MW6500s are marked as being from '82.) Could there be an issue with the inductors? If there was a cold joint anywhere in the circuit, there would be no sound at all, right?
Again, any feedback would be GREATLY appreciated.
