Bring on the criticism...

There must be an imaging issue. There is no way that two speakers will sound any good unless you already had a serious imaging problem. Admittedly the baffles, with all those edges and diffraction points, on the Maxx are bit baffling.

I agree with the several previous descriptions of the adverse effects you are likely to encounter. More specifically, a major effect is likely to be some degree of Comb Filtering. That occurs due to radiation of the same frequencies from different drivers in different locations, with those drivers having differing path lengths to your ears, resulting in differing arrival times.

I believe that the subjective result of that is a general "cloudiness" and loss of clarity. Of course, it is likely to be most perceivable on high quality material.

I did this when I blew the tweeters in my JBL L88's in the '70's. Removed the tweeters and sent them to JBL for repair/replacement (which they did with no charge, even though I was not the original owner of the speakers. Wow!) Anyway, I had a month or two with no tweeters. So since my Pioneer receiver had two sets of speaker outs, I connected a pair of no-name speakers from my first department store brand stereo, and placed them on top of the big JBL's. Problem solved.

If you can afford to do that, why can't you biamp?

Can't bi-amp Maxx's

you could pay a lot less for a PA system that could do that

But it wouldn't be a Wilson PA....lol

my only question is with the volumn set in one position does the sound level from speaker set A equal the sound level of speaker set B?

Both speakers are coming straight off the FPB450's so they are being fed the same power.

Correct they are being fed the same power but are they playing at equal sound pressure levels or is one pair louder than the other;that's what I was questioning.
