Yeah, my best input is this:
* make sure the two passive radiators (top slots) are damped correctly, but not too much. It's a sliver of putty at a time until it gets too much, then back off a sliver.
* the tweeter and supertweeter attenuator pots on the back are likely a bit off from each other (i.e. left speaker one might be midway at 12 oclock, the other at 12:30, depending on where they min and max out at), so I would find a 1/4 set of knobs with center markings and then use them for setting levels. Also, a Radio Shack SPL meter helps to find symmetry between the l and r.
* like most any VMPS design, they love to be toed in to cross in front of the listener by about two feet. I invested in a $20 laser level and found that toe-in symmetry was incredibly beneficial. I just set up an album cover or something in the front of the couch/listening seat, then pointed each side of the speaker to point equally. Symmetry from side walls is important, too.
I just looked through all my stuff but couldn't find the old flysheet. I'm sure I gave it to the new owner. I'll ping him if I can find his email.
