Sub Frequency Response-How flat is good enough? (1 Viewer)

My room is 19' x 19' x 8. From what I have read, square rooms are horrible as far a sub frequency response. I started with the sub in one of the front corners and had huge dips and peaks. After moving the sub around, I found a spot near my seating position that is pretty smooth and sounds great.
There are still seveal peaks and dips, but they are much tamer now. When I run a low frequency sweep, the difference between the highest peak and the lowest null is about 5db. Is this pretty normal, or is this still way too much.
I know with this room, I won't be able to get perfection, but wondering if this is good enough.

Thanks

Greg, if you really only have a difference of 5 dB between the highest peak and the lowest dip, I think that's really good, especially if you've done that without any equalization.

The next step (if you want to really tweak the response curve) would be to add an equalizer like the BFD.

Thanks Guys,

There is one peak that I didn't mention. It is around 24 Hz. It is rather large, but I figured it would be too low to have an effect on music, and would help with movie LFE. Would you guys agree with this logic.

I would agree. Consider yourself lucky. I'd be psyched with that kind of natural in-room-response.
