I need help with EQ and crossover settings for a OB I’m playing with. I'm using REW, UMIK-1 and MiniDSP 2x4HD and my total experience with all this is just about 3-4 days. I’ve done a bit of reading but the stuff that stood out most was - a couple of videos (links below) and this thread www.avsforum.com/threads/si...ow-to-inte...49924/#post-22789786. Also AustinJerry’s setting up REW guide.

There is a lot of material I should read and I will in due course. Admittedly I’m a bit impatient and am hoping to start with something basic and hear some improvements.

The setup is a 1xPRV 10FR300 full range and 2x PRV 15W1000V2 woofers in parallel on each side. Running REW on MacBook Pro. In the MIDI setup MiniDSP is set to 2 channel 16 bit 48 KHz. In REW I've set output to MiniDSP and input to the UMIK-1 with calibration.

To start I'd like to confirm I'm measuring correctly.

1. On the Mac, should the MIDI setup be set for 2-channel 16 bit or 2-channel 24 bit 48Khz?

2. I'm taking measurements with the mic at listening position with mic facing straight ahead (i.e not towards the speakers)

3. It is recommended that I take measurements 60dB above the noise floor. Is it too bad to do it at say 85dB? I understand that more of the noise floor we can ignore, the better.

4. Somewhere it says I should do a 10-20Khz sweep even for a subwoofer? But the specs of the PRV 15W1000v2 say 40-4KHz and I don’t want to damage the sub.

5. I assume I have to take 4 measurements (full range and woofers on left and right) individually and EQ each individually. Finally I take one overall measurement and see how it looks.

I’ve attached a response of the left and right full range at 85dB and I used 1/6 smoothing. Does it look right as in expected? Is it fine? Do you need more information? Should I EQ? If yes, what settings would you suggest?
