I've read some conflicting information and I'm not to sure on the right way to setup a mindsp for optimizing subwoofers. A while back I used REW to try and flatten out two subwoofers, both located in the front of the room. Fast forward, I recently acquired another subwoofer and placed it in a back corner. That led me to looking into how to do it all over again and I came across Multi-Sub Optimizer. I ordered the minidsp-HD in hopes of eventually learning how to use MSO along with REW. The first time I used REW, I used a laptop to run REW straight into the minidsp and directly out to the subs bypassing my AVR. I have a Win10 HTPC hooked up to my AVR, would it be better to run REW test tones on the HTPC out through the LFE on the AVR to the minidsp? And if so is there anything I should do with the AVR first? ANy help would be appreciated, Thanks for looking.
