Just used the Room EQ Wizard...what am I looking at?

[slickshoe62]

I just got through my first few sweeps of the Room EQ wizard. I have a fairly small room (12ft X 9ft with 8ft ceilings) with some auralex for the first reflections and a couple tube traps in the corners. I want to clean up the muddy bass and get better stereo imaging out of my monitors, so I figured I'd get a feel for whats wrong with my room through the EQ wizard software. Now that I have a graphic representation of my rooms faults...........what am I looking at?? (pic attached)

I see a peak at 93.1 Hz, which falls 15db at 105 Hz, then a bump up 20db to136Hz...
does this mean I need more bass traps? Do I need to make specific traps to tame certain bass frequencies?

Can anyone with experience on this please chime in with what my graph means, or even better, show me how to read and interpret these frequency graphs.

Also, what does the waterfall graph represent, don't really understand what those are about either.

thanks in advance

Basically if you want it better you just have to keep adding bass trapping to the corners. Your room graph does not look at that bad, but there is always room for improvement.

Yes.

No, use broadband absorbers, as thick as possible.

This article is about the ETF software, but the principles apply to all such programs:

just had some other quick questions for anyone out there,

should I be using 2" or 4" thick 703 fiberglass for my 2'x4' panels?
4" for just the corners and 2" for side walls to cover early reflections?

p.s 703 fiberglass is really expensive out here in the 808 state!! (hawaii)

Yes for the corners use 4" (better yet 6") and for the early reflection points use 2".
Instead of 703 can you get mineral wool? That will work just as well.
