Well, I finally got REW working with an external sound card and the EMC mic and I started some scans. I disconnected all speakers but the sub and set the crossover to 200. Not sure if I should leave it at 80 as I normally do or not, but I thought I would see the response up to 200 this way. And I set the BFD in bypass mode. Is this the best way to proceed? In any case, I ran a scan witht this result:
I configured the filters in REW and it indicated this result:
I applied the filters and ran another scan with these results:
Better but certainly not what I expected. The REW prediction is not very close to the final result.
