Need help from you acoustical experts

Reading @elliottbnewcombjr's post and looking at his photos reminded me of this rather old site, Mother of Tonehttp://www.mother-of-tone.com/index.htm. It deals with vibrations and materials that carry them.

They sell, as well as instruct on construction of, birch wooden panels treated with organic lacquers that have favorable vibrational qualities pleasing to the ear. There's also a section of room acoustics that might be worth a read that goes contrary to some of what's been posted here. 

Here's a shot of the owner of Audiovector's room and the treatment of the front wall:

Posting this had my muse whisper in my ear that something as simple as textured wallpaper can do wonders for reducing echo and reflection, which may be all one needs for their room. Just more food for thought.

I have to make a correction in that the boards are made of spruce and not birch. Must have had a brain fart when composing the above post.

All the best,

One of the things I should have made more clear in this thread was that these speakers were designed to be close to the wall and not toed in, unlike most others.

From the manual: "We have found that placing the speakers from 3” (75mm) up to 20” (500mm) from the wall results in the best bass power and tightness. Please experiment but make sure that the speakers have had at least 500 hours on them before making your final decision".

I have tried moving them away only to loose bass. The bass response is great right now and I have taken the diffraction wood panels off the front of some of the treatments which has helped. These speakers worked great when I had to share the living room and was not able to have a pair that needed to be pulled far from the walls to sound the best. 
I think that since i have a dedicated room now, that It may just be time for different speakers. 

I think we'd all agree that speakers designed to be close to the back wall are a design compromise to assist people who don't have the room or the WAF.  Had some Wilsons with the same issues.  That placement increases the natural bass of the speaker and so suggests they reduced the bass output in the design.  Imaging does require about four feet of space from the wall.  You might consider one or two quality subs to augment the sound, a good idea in any case.  Why don't you give VS a call and get their thinking. I'm sure they hold their value well, so you could change them out for a brand that doesn't require the close to the wall placement.  

I did try a pair of svs subs, but ended up returning them. 

I may call VS.
