My take on Barry Willis' review of your speakers was that a small room didn't allow him the space to properly place the speaker for best best response and soundstage info. In the small room he was forced to listen in the near-field where the speaker didn't perform at its best. This could also raise questions about driver intergration (in the near-field). Willis is very specific at the end of the review stating that the speakers will perform best in medium to large size rooms. I doubt even extensive acoustic treatment will truly solve your issues with this speaker in your current room.
Room Size and Loudness
I'm at the room tuning stage with my addiction and one of the various room problems I want to address is a loudness issue which plays out this way: To really get the best out of my speakers I need to run them at a level that makes them too loud for my room -- every once-in-a-while I can handle a Who concert, but I don't want to do it every time I fire up the system. I knew this could be a problem for me when I picked up the speakers I'm using (in April) but I like the speakers and the way they fit in with my system. Can I use acoustic treatments to solve this problem (I'm sure that might raise other problems -- but I need to know the options before I can identify points of compromise). For example, would lining a wall(s) with absorption foam, etc. be a solution? Any thoughts/comments would be greatly appreciated. Thanks!
