Recently purchased these for new home.

Love them but noticed that one speaker seems tad louder than the other. Switched positions of the speakers (but kept everything else the same) and inbalance followed the speaker- track with vocals only on one channel which vocals seemed a bit quiet in relation to the other were indeed comparably louder when speaker position was reversed.

My dealer spoke with Magnepan but no ideas as to the cause. Short of sending them back, any thoughts- could it be something like a bad fuse holder?

Thanks in advance and happy new year.

I would ask Magnepan for a new pair... If you just bought them new., posted on December 31, 2016 at 11:26:31

If they are messed up and no one knows WTF is wrong.
And they are new? Yes ask for a replacement pair.
No question.
And no, I would NOT accept sending them back to be repaired.

Added. I own 3.6 bought new back in 2010. Lucky for me never had any problems with them.

My 3.7i's, about two years old, are slightly misbalanced. One db or so. I assumed it was within the acceptable parameters of variance, and never even mentioned it to the dealer.

Years ago I purchased a set of MMG's directly from Magneplanar and they sounded unbalanced to me (one louder and clearer than the other) Contacted Magneplanar and they told me to send them back and they would exchange them for a new pair. The new pair was fine. It turns out that the membrane in one of the exchanged pair was not tensioned properly.

There is a small chance that it could be a phase misalignment; I remember when setting up my 1,7's I simply reconnected all cables and wires (put colored labels on each connection) and attached them to what I thought would be perfect phase alignment, but one speaker often played louder than the other. Hard to swallow but I had been listening to my omni directional speakers for 10 years and had never been bothered enough to investigate. The problem was corrected and everything played louder than before. The sound space became most dramatic.Good luck.

Use a sound pressure level meter to confirm.

and place the speakers in the same location when doing the comparison and preferably use a band limited pink or brown noise signal (300Hz to 4KHz) is a good range. Note that Brown noise more close follows the frequency distribution of music - pink noise is the equal energy per octave signal.

Perhaps through oversight Magnepan neglected to give the 'i' treatment to both of your speakers. Alternately one of them is lesser 'i' than the other. e.g.: i/2, i/4, etc.
