My room - frequency graph

Here is a frequency graph showing the response of my room. I used fuzzmeasure to generate this. I'm a little concerned about the falloff at around 8k. Also, there are several dips and whatnot throughout, but since I have nothing to compare this to, I'm wondering if someone who knows a little more about this could chime in with their thoughts. I used an analog Radio Shack meter for the test. There was only one speaker generating the sine wave and the meter was put exactly at listening position and height.

Thanks!

From what I know, this looks excellent, especially in the Low End. No idea what's the deal with the fall off at 8kHz though...

indeed... thank you so much Ethan....

I just have to buy a new microphone for our Smaart system and the good news is that the Behringer comes really close to the Earthworks you took as a reference in your charts...

the weird thing is that for the price of one Earthworks Microphones you can buy 25 (!) Behringers ...

although I know Behringers reputation I think I'll go for the ECM8000 for room measurements... or am I to miserly?

Kind regards from Belgium

Pedro
