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?

verify tight and in phase and level controls on speakers set same.
swap at amp end only L to R, both low and hi frequency bi wire,  IF level change to opposite problem, it’s amp or upstream.

2db is way out of spec if speaker in same acoustic space w same input.
