Make sure the adjustments for tweeter and midrange on the rear panel are set the same. (Sorry if that seems obvious ...)
Vandersteen 3A Signatures with 2 dB difference between L and R Speakers
I just purchased a set of 3A Signatures CPO from a dealer, and was running a frequency sweep using a calibrated mic and it shows a 1.9 dB difference in volume between the L and R speakers. Is this within the margin of being acceptable? I thought these speakers came in matched pairs, do they not?
