Xcon 15" D2
The enclosure was designed by Pete at http://pwkdesigns.com/
I'm noticing now that the enclosure is actaully a 6th order, which is even more impressive with regard to group delay and transient response. I'm sure between the one octave sub-40hz passband and T/A, it's not an issue. Again, very nice.
I'm not Scott, but he would say thank you!
With T/A and steep filters, splitting drivers is not as big of an issue but there's still penalties involved when compared to setups acting more like a point source, coax and full range.
i have a mk4 also...what you doin for power? alt? batts?
