Dipole Asymmetry

imgood, tomcy6 has a point, and a simple solution to my mind.  Try duplicating the approximate shape of your left rack behind the right OR put panels behind both.  With the first, you mess a little with the diffusion behind the speakers.  With the second, you simply reduce the delay time.  You might try both just to see the difference and which you'd prefer.

I have dipole ribbons (Heil AMT's) 2' from the wall...sounds good to me. *G*  Lucky to have 'blank walls' behind though...

This is audiophile neurosis at its best (worst) .If in a blind test anyone could hear which side had a rack and which side did not deserves the worlds "best ears award" . 

With this mindset, Maplegrove, do you also believe acoustic treatments or tube traps offer no merit? How about speaker placement?

@maplegrovemusic

Compared to cables, fuses, etc. NOTHING measures a bigger improvement than acoustic treatment. 

Honestly though in this case the much bigger issue is putting di-poles so close to the walls. Fixing or compensating for that part first would be my first priority, second dealing with the bass response, third the rack.

Of course, there are simple things to try. I would turn my rack sideways and cover it in a courtain. :)
