Got a pair of Mapleshade Bedrock Ultra's yesterday and been playing with speaker placement. So far the product does as it claims. I am using a $200pr of Cambridge Audio S30's with them and i can't believe the sound that is coming out of these things. My room is only 12.5ft x 11ft and i always had a 45hz peak and quite a bit of midbass suckout. I ran some tests with tones and a decibel meter and i still have a peak at 45hz but the midbass is back and i went from a 13db difference between 45 and 80hz to only a 5db peak. The soundstage is wider and the center image is great. Working on the tilt back now, right and left image is a little low. Hopefully i can get it right.
