I have finished my room, I will post pics later. My setup:
JBL 4350's (studio version)
Mac Intosh MC7300 (low)
Mac Intosh MC7150 (high)
Mac Intosh C38 Pre-Amp
Wadia CD player
JBL active cross-over Model 5232
I bought a sound level meter at Radio Shack (low end unit) and measured the frequency response of the 4350's paying attention to the Left-Right balance.
I found that the system is massively out of balance, depending on the freuqnecies. I placed the meter at my listening posisiton, or 11feet from the 4350's. I have attached the graph of the frequency plot.
In some cases, like 126Hz, the differential is a much as 24db between left and right.
I wonder if there might be something wrong with the electronics that I use? Any ideas?
