EQ Filter recommendation for midrange speaker not working quite right

Hi Guys,

Newbie to REW, so bear with me please.

I'm doing a time alignment and EQ on my car system. I've got an actively crossed over three way system up front (tweets, 3" mid, 8" mid-bass). Some 3.5" coaxes in the rear deck for fill. And a 10" sub. I've got the JL Audio 8 channel amp that has built in DSP for crossovers, time delay, and 10 band parametric EQ. I can EQ each component individually (one EQ for the tweet, one for the mid, one for the mid-bass, etc).

So I've got my Dayton USB mic up and running, and am using the pink noise generator in REW to feed back in to the car. All working great!

So I started reading up on the "EQ" window in REW. My understanding is that rather than me tweaking my parametric EQ till I'm blue in the face trying to get things flattened out a bit, I can let REW do it for me, and it will give me some parametric EQ settings I can plug in.

So I set it up for a generic EQ (I'll have to manually assign its recommendations). And I've read up on it a bit and it seems to be working, except it seems to not care about the upper end of the range I specify. This is the 3" midrange I'm trying to EQ. So it has a 24db/octave crossover at 180 Hz for the high pass, and 2400 Hz for the low pass. I set the "Match Range" for 200-2200 Hz. And it seems to EQ good lower in the range, but leaves a big dip around 1670 Hz. Surely I'm doing something wrong. Can anyone advise?

REW will not try to do anything with dips that are further from the target than the individual max boost allowed.

Ah ha! So I guess I need to set the target level a little lower then.

Got another question if I can ask... Obviously, my EQ doesn't match any on your pre-defined list. Can I set the max number of EQ points to 10 somewhere? Or do I need to find an existing EQ that has 10 and use/try that?

REW will only use filters that are enabled and set to Auto, so disable any you don't want REW to use, or set them to Manual rather than Auto.

Got it. Thanks so much John! Fine piece of software you've got here (I'm a software guy, I can definitely appreciate it!)
