Problem with Mesa 4x12 Cabinet
Well, I recently upgraded and modified my Mesa 4x12 8ohm Rectifier cabinet not too long ago. Currently, it has 2 Mesa Black shadow Speakers on the top half and a pair of Vintage 30 speakers at the bottom. All seems well when I run the cabinet in mono mode but when I connect the cabinet in 4ohm stereo, one sides to be louder than the other...
To explain this problem even further... I'm using a Mesa Simulclass 2:95. For this example, Channel A is connected to the left side of the cabinet at 4ohms and Channel B is connected to the right side at 4ohms. When both are connected in this fashion, the output on channel B doesn't sound as loud as Channel A. Unfortunately, when I invert the connections from the back, Channel A doesn't sound as loud. Otherwise, the cabinet sounds fine if i run it at 8ohm mono.
I am pretty much trying to find a solution to this problem even though I have no idea what's wrong with my cabinet. I've rechecked and resoldered my connections and the problem is still there. I've even connected a Carvin cabinet at 4ohm stereo before and both sides sounded even. Any help would be appreciated.
