A lot of thanks to those who finally replied!!! Just needed some feedback.
I ran the sets up and these were the results without going into too much detail. All were given 800 wrms. All ported.
All set ups had very nice SQ. Two IDQ's had a bit more SPL at moderate listening levels, but if pushed harder did not hold their ground. Started to distort, and bottom out a bit. Focal maintained excellent SQ throughout all volumes, but had the least SPL of three set ups. The Mag maintained amazing SQ throughout, and pounded harder than Focal. A bit less output than two IDQ's at moderate volumes, but when pushed loud and hard, it just laughed and wanted more. Zero distortion. Mag could not be matched at loud volumes. A clear winner for me. I am keeping it. I did not know how good this sub is until recent tests. I think Mag may take 1500 watts with ease. I love it!!!
I place these set ups in this order:
1. Mag D2
2. Focal 33KX
3. 2 IDQ's
BTW Mag was a clear winner. Not a very close race. Almost not fair
