Here ya go. I'll dash out and get some beverages as well.

You get no pity from me - I had axioms in a dorm room for 3 years.

Dan's back.

Keen observation.

This one's for you Mark.

I have a bit of an epiphany the other night as I was staring at my room wondering why I have such a nasty intractable 52Hz peak.

I have been looking at my apartment all wrong. My HT is in a 20' x 19' room with a large obstruction called a Kitchen. The outer boundry walls are either poured concrete or concrete block. The kitchen walls are probably plaster on metal lath. The room is open the full 19' at both ends (hallway and dining area with the kitchen sitting between, breaking up the room a little.

I live in square room suckage! ::waaaface::

WOOHOOOOOO!!! I now have a room that sucketh a little less.

I picked up a BFD DSP1100 second hand on the weekend and have been playing to get it set up.

I used some automatic features in REW to generate a set of filters for me. As a test I entered the 56Hz filter into the BFD and ran two measurements in REW, with and without filter.

The filter result was damn near exactly what REW predicted it would be.

I'm so excited!!

Blue is with the filter engaged.

I added 3 more filters tonight and surprisingly the overall effect is very subtle. Its hardly noticeable at all for music even stuff with reasonably low pipe organ notes.

I tried the filters out on LOTR Cave troll and Balrog scenes, and the difference was more noticable, but subtle. There was a reduction in boom for some of the low lfe stuff and maybe a little tightening in the sound like where parts of the bridge start to collapse.

I am quite surprised a 14db cut at 52Hz seems like such a subtle difference.

....and I just can't hide it!!....

Have you tried moving your sub around and playing with the BFD now that you have it Fred? Maybe you can find a more suitable position that you can tweak slightly with the BFD?

That's it Fred!

One more improvement and you're outta the club!
