    Im currently using the SVS PC+ 20-39 with a denon 3802 AVR as a preamp. the crossover is set at 80Hz at the AVR and disabled at the sub. I recorded the following values with my RS SPL and frequencies downloaded from snapbug site. sorry about the numbers but i cant get the graph uploaded to the site. the worst dip is at 80 Hz which is the crossover. would getting a BFD be worthwhile in my case to try to even things out and would there be any noticeable difference. or is it better to try to move the sub around to attempt to flatten response. any advise would be appreciated.

    You will find many here who use BFD. My room had spl of 66 at 50Hz and 92 at 31Hz. The BFD flattened it out. It made a big difference [​IMG] . Moving the sub may have some effect, but I think the different spl levels are caused more by the properties of the room.
