Apologies. This was the "subwoofer" setting. I did 2 512k sweeps from 0-200KHz. The different graphs relate to various gain levels and crossovers.

Strange, it looks like just the opposite, i.e. the mains though a high pass. Note how the bass below 100 Hz rolls out more severely with each graph...

These graphs all look like they have smoothing applied. Have they?

Yes, 1/3 octave smoothing.

We typically suggest no soothing for subwoofer graphs. Just prepare you, that'll make it look worse than it does now.

I feel very conscious of the location of the sub i.e. right next to me: something I thought I could calibrate out. A bit disappointing really given that it really can't go anywhere else.

At least make sure you have delayed appropriately.

Wayne
