Using Room EQ Wizard (REW) to measure FR

How many filters did REW setup? I would discount any with only a few dbs (<4) This will at least give you an idea of how many EQ bands it would take to get that dotted line FR.

Bummer about the placement issue. I'm pretty much stuck with mine as well. But, if you don't get rid of that null with placement you might just have to live with it. You could try to boost it with an EQ band, but often it won't make a difference. And even if it does you will lose head room in the process.

I want to measure with the Mains + Sub next and play with the crossover. I'm not sure when I will get to this, but I would like to see how it looks. I also want to play with the other features of REW.

Here's the graph of the sub response (solid line) and the predicted effect of the EQ filters automated by REW (dotted line) plotted against the target level (solid blue line, 77.1 dB....I guess I ran the test a tad hot ):

Here's my second shot at adding some manual filters. I went on the assumption that my limit will be 12 bands of EQ, because if I were to purchase something, it would likely be the Behringer DSP1124:
