i finally got Windows and Winisd running on my computer and im trying to model these two drivers.
actually its 2 IXL's in 18cft. getting 1600 watts VS 1 UXL in 11cft. getting 2000 watts. both tuned to 17Hz.
if im doing this right, the 2 IXL's have a small 1-3 DB advantage above tuning, but for the most part, the single UXL keeps up with the dual drivers in the bigger box
