Dipole Asymmetry

I am considering purchase of a pair of Martin Logan Summit X speakers. In my room, I am somewhat constrained for speaker placement. I could place the speakers about 3-4 feet off the front wall. My main concern is my audio rack would be placed directly behind the left speaker, while there would be nothing placed behind the right speaker. How detrimental would this asymmetry be on sound quality?

I agree that is pretty close to the rear wall. Solutions would be acoustic panels from GIK Acoustics.

Also, put a panel between the speaker and the rack. It won't be ideal, but much better. :)

@cleeds time.

You need about 15 ms between the direct signal and first strong reflections so your brain builds up the image and tonal characteristics of the music without significant blurring and smearing.  At about 1ft per millisecod, 5ft x 2 = 10. Too short a difference.

@cleeds Sorry my friend, i may be a little brain fogged right now.

If the speakers are less than 8' or so from the rear walls, the reflections would occur before 15 mSeconds.  The idea is to reduce as much as possible all reflections within the first 15 mseconds. Panels behind the speakers will do this, to some extent. It won't be perfect, but reduced.

If I'm still being unclear I'm sorry.

Good way for you to loose weight! ;-)

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.


Best,

Erik

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