Hi. I have a REL Strata III that used to sound terrific in a different house. In my new house it sounds rather lifeless and needs a lot of volume to generate acceptable bass levels. The new room is smaller than the old room but is much more acoustically dead. I now have the time and room to fix this problem. I'm gonna try moving it around tonight but something I was considering was putting a 2' x 2' sheet of MDF under the sub instead of placing it directly on the plush carpet. Anyone ever try this? What are the pros and cons? Thanks! leo.
