Looks good, weverb! Have you been studying/lurking in the BFD forum?

No. The deal for the Behringer fell through, so I am lurking for a used one still. I have a couple of feelers/inquires out there though.

Re: REW Noob

Was just playing around this morning.

Red - main sub and MBM
Green - main sub only (xo active 40-45Hz)
Gold - MBM only (xo bypassed)

Look like my receiver is still sending a lfe signal even after it's setting of 80Hz and the main sub does not fall off very quickly!

Re: REW Noob

Looks like I can remove the Noob now on the title. Here is my new graph.

Red - BFD off
Green - BFD on

I am only using three filters.

Looks great! Might want to pull your 66 Hz filter down a few more dB , so that everything >45 Hz overall tracks the house curve a bit better. Too much up there compared to below there can make things sound a bit bloated.

Wayne

Re: REW Noob

Thanks Wayne,

I appreciate your feedback and help. I figured I would start to listen to material before making any more changes. The hard knee curve will more than likely make its way into my set-up.

Re: REW Noob

Well, after a lot of help from Wayne and bruceK, I have decided to move on to my mains. First things first, I only have a RS meter for now. I will decide to get a better mic depending how this process goes. Here are graphs of my sound card and actual measured sound card. It looks like there is going to be problems trying to measure anything over 2kHz with this sound card. Am I looking at this correct, or is all that variation ok?

All that variation is less than a dB.

To test that the soundcard file works and that your card is good, simply connect a cable from line-out to line-in and take a measurement with the newly created soundcard cal file loaded in REW. It will return a flat line............

That's what I did to get the bottom graph. Can you explain how to test the highs? When I went to try today, the measurements were steadily declining after 200Hz. It looked like the highs were almost not turned on. I tried setting the level to 81dB using the REW sub cal signal to get a 75dB reading from the highs. These are the readings I get when I use the receiver's pink noise test. Then I tried setting the level using the REW speaker cal signal. Not once did the mains maintain the level at which the calibration was set to. Every time, after 200Hz, they just started taking a nose dive all the way out to 20kHz. I did not save the graphs because I thought there was no point since something was incorrect.
