Mike, I took a bunch of measurements a couple months ago with the S3601s and I thought that I was doing something wrong with the RSC setting prior to running REQ, I was comparing the graphs to the 7201 I had for a short time here and thought they should be similar. I don't hear the gradual roll off, I think because of all the energy output above the 20 Hz range. I feel a bit better now as I was concerned with the measurements, I would have not even brought it up if I didn't measure the bass response, I can't hear it.
I calibrated with RSC at mid point and then back to large, the red graph below the others was with the RSC put back to mid, didn't change anything except attenuated the low bass output. These are all at different mic locations at the LP.....
I was used to seeing this type of extension, so I really thought I was doing something wrong, I'm in the process of changing my room all around and haven't measured anything since January. I'm happy you guys brought this subject up about the roll off, I was really concerned and now I'm going to just enjoy what I have and not fret over this.
I guess this shows what you're talking about even though the sweep was started at 15Hz, about a 10dB roll off starting at 16-17Hz.
Any replies welcomed, thanks.......I'll be posting some new measurements soon along with compression sweeps, I finally have these subs setup where I think they will sound best.
