I think I’ve done OKWell, I used Hornresp because WinISD is only half space. Was I in for a surprise This is what you get when putting these in a corner:

This is at 2.83V (which is about 2W when both are in parallel). That's no 91 dB either. Spec sheet says 93 dB BTW: "([email protected]) averaged from 60 to 200 Hz".
So how loud will 70W go (I assume 70W each)? Way north of 125 dB @ 1 meter It's safe to say that this will be plenty.
Now I always found that Hornresp seems to be very positive in SPL graphs, but WinISD shows about 112 dB at the low end in half space, add 12 dB to that, and we're almost back at the Hornresp figure.
Can you simulate the port output separately? Your chart makes it look like it its frequency is lower than what I thought I designed. It has been a while.
My memory must be hazy on sensitivity as well but what does 2dB among friends, especially if it’s conservative?
As I said earlier each subwoofer is driven separately by a stereo power amplifier, which can output large current (a NAIM NAP250).
