Been out of all this for quite a while. Anyway, my UMM-6 microphone and minidsp 2x4 should arrived here today Planning on playing with everything this weekend with the wife gone. I have been experimenting with REW and am at the point of frustration. I want to learn to measure my dual subwoofer setup and see how it's interacting with my room. I think I have everything I need: A laptop with separate mic and headphone inputs, Surface Pro, Behringer 222 soundcard, Radio Shack 33-4050 SPL meter, minidsp 2x4, Dayton umm-6 mic, and 6ft TRRS male to female cable. I know that some of this is redundant like the laptop and Surface, but I mentioned it to hopefully be guided to the best option. With my gear, is there a simple guide to get me on my way to start doing subwoofer measurements? My goal is sub equalization for now and learn the rest later. My HT gear is a Yamaha 3070 receiver, 5.2.4 atmos speaker setup with Klipsch 15 inch and SVS PB-12 subs. I'd appreciate a little help , thanks.
