Ok here we go, I believe I have everything hooked up and ready to go. I recalibrated everything and here are the first graphs. not sure what was going on with the 2 that seem to be all over the place but it seems that i have a couple good runs there, and they don;t look to tereabley bad, I just need to pull down in a few spots.

Graphs number 1 and 4 are showing some strange results for sure.

It looks like a form of comb filtering, but I suspect it may be a clipping in the soundcard. The next time you see a result like that, check the REW Scope tab to get a picture of the input and output sweep levels. See if the input level is overdriving.....

Either way, yeah, it looks pretty good. You have a couple of small peaks that can be taken care of fairly easily.......

Well my last post got lost, but I have not recalibrate the sound card with the mixer inline so I am going to do that for sure, and then check my levels again I do have the sound card turned up pretty high. And this all with no acoustical treatment yet. Unless you can count the riser filled with insulation.

Oh sorry, I forgot to mention that I got a Behinger Microphone and mixer to hook up for testing ;-)

Well I have made a number of changes and I suppose I should remeasure ;-) I have the new Emotiva Amp and surrounds and some acoustical wall treatments, and I have to say that I don;t think I have made any new measurements since the bass traps and screen wall were moved. I better get busy!

Don't worry, you'll have plenty of time ...tweeking never stops

P.S.: I read that after around 170-200 hours of usage the sub will sound a lot better
