Awesome setup. NICE. Scott(Fi) makes some killer subwoofers!!
Just read your thread, Blitzer. I'm a little relieved since I saw the same dropoff in the low end as you did, even if it SOUNDED like it was outputting significant energy way below 15Hz. I've boosted the low end a bit and cut my very similar 24Hz node significantly. I'm now a little worried about overexcursion since I've boosted the VLF part pretty significantly (6dB)
