I noticed over the last couple weeks of listening there seemed to be a left bias to the sound, vocals and higher frequencies seemed to be attached to the left speaker. I found this odd as a hearing test a few months ago revealed that my right ear is much more sensitive to upper mid range and lower treble frequencies than my left. Running the YPAO on the receiver as a check showed the right speaker needing few DB more in these frequencies, and a bit more volume. Listening to each speaker independently confirmed there was a difference, and it seemed to be all in the tweeter.
I'm an automotive technician by trade with a big focus on diagnostics so I'm no stranger to taking things apart and testing them so I dove in with some resistance tests on the tweeter and from it's wires to the binding posts here's what I've found.
Circuit Left Right
Tweeter 2.9-3.0 ohm 3.0 ohm
White to Pos 8.8 ohm 1.2 megohms and dropping
White to Neg .6 ohm .6 Ohm
Blue to Pos 8.4 ohm .68 megohms and rising?
Blue to Neg .2 ohm .2 ohm
It appears to me the right has a capacitor that is charging/discharging as the meter sends a current through it, where the left has no change at all, however however I admit crossover networks are a bit above my head, and more complex that what I deal with on a regular basis so beyond that I'm stumped... I visually inspected both crossovers as good as possible (wouldn't come out all the way, wiring too short) and didn't see any obvious broken solder joints, cooked boards or leaking capacitors, so, where do I go next, or is the answer as simple as the board is bad and needs replaced...if so, which one??
Any input is GREATLY appreciated!!
