I have used this combo in 2 different rooms. I just recently moved to another house. My other house was my dream home that I built myself near a major Ski resort here in upstate NY. Well, good old NY state taxed me out of the house. Anyways, that room was 20'X 22'. This room now is much smaller. I think 11'X14'. the speakers are along the longer 14' wall because of doorway issues. I did have them along the shorter wall at first. In both rooms this has been an issue.
I have wondered from day one if they were the correct 8" drivers. I bought them here at AG last year and the seller said the 8" and midrange were replaced by Vandersteen.
The midrange is almost a clear or opaque color with what seems like standard silicone smeared on the foam surrounds. The 8" is a poly type cone. I tried to email Vandersteen to see if these were stock drivers but trying to get them to respond is impossible.
I have tried several positions from the rear wall. It does help some but the issue never goes away.
I kick myself for ever selling my Proac's. I just got board and had the itch to try other speakers. None I tried ever came close to them. They were the cheaper Studio 250's but the sure did sound good.
I am glas my audiophile OCD is all better now.
This is the first time I have been back to this site in many months.
I have tried both positions and I am currently running in ultralinear to get the most power thinking maybe the amps were clipping.
