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.
Need help from you acoustical experts
Here is the latest version of my new listening room. Everything is nice and symmetrical. Depth is ok, width could be a little better. Most of the treatments are from GIK Acoustics, placed where they recommended.(mostly).
Treatments on the side walls are at 1st and 2nd reflection points.
Walls are drywall screwed and glued to steel studs, paneling glued and strapped to drywall and filled with Rockwool. The ceiling has R30 insulation covered by CelingMax grid, screwed to the joists (not hanging). Dedicated circuit for the stereo, and HVAC ducts insulated to keep it quiet.
Yeah, it’s very quiet. Creepy quiet.
My issue is probably with the treatments. Midrange/singers are very forward, and high in the room. Usually as high as the white music note panels, and sometimes the singer sounds like she’s on the ceiling between the speakers.
Anyone see a mistake I’m making with the acousticsounds panels, either placement or type?
I’d like to post some pictures, not seeing how to do it. Guess you'll need to look at my profile.
