I'm curious about what degree of rolloff everyone has found. When I bought mine about 3 years ago, I only remember a single review being out. That was on secrets and it showed significant rolloff at 30. In fact I just checked and its still there(subwoofers under the christmas tree), but I cant seem to post the link.
When I bought mine, I had capeted floors and sheetrock. I also own RF speakers, and I never noticed any issues. In the last month I moved into a stucco house with hard tile floors. I know there are several other factors, such as room size and shape, yet now I cant get enought low end for movies. If I turn it up(only about half gain)which is about 6-8 db hot with a rat shack meter, then its way too much bass on most things. Just wondering if I got a para eq and turned up the bottom frequencies, would I burn out my amp?
Also my speakers sound like garbage now, I really need to get a huge rug for starters.
