BFD or passive room treatment

[Londondecca]

Following the successful soundproofing of my room and the rearrangement of the furniture the sound quality has reduced with the exception of the subwoofer ( Rel Quake). This has gone from being acceptable to very poor, I now have a very large boom at about 80Hz and unable to hear anything below 50Hz.

I have tried moving the sub around but its location is now limited by domestic aesthetics.

Therefore I was thinking about either buying a BFD or the more traditional room treatments from RPG.

I have read the beginners guide to the BFD but technically I am incompetent and it only relates to a small part of the frequency range but the bass quality is very poor.

I have a BFD and it works better than I expected, when used with Room EQ Wizard and a Radioshack SPL meter its pretty simple to do.

The fact you have lost the deepest bass could be a problem though unless you have a sub with a lot of headroom you don't use, because trying to push up the gain on low frequencies could cause clipping of the sub or distortion.

Putting the sub in or near a corner is a good way to boost the lowest frequencies but it sounds like you've run out of places to put it.

If there's anywhere left to try placing the sub, that is definatly the best start but I would still recomend a BFD to flatten everything out.

The other problem might be the relationship between the main speakers and sub because your peak is likely to be in the crossover. Try playing with the phase on the sub to see if this improves things.

Hope this helps in some way.

Edit: You say the sound quality has reduced? I assume you mean improved?

Londondecca, what have you changed in the room?
