Yeah the 3.0 @ 28hz looks best out of the 4. You wouldn't want to tune any lower than that anyway. You should try graphing 30hz to see what you get.I have been back and forth on my subwoofer situation. I love my little P3D4-10 and the thought occurred to me that I could run two of these little *******. So I put the parameters into WinISD and came up with 4 vented boxes... I was thinking that box #1, 3.0 cubic feet and tuned to 28hz looks great... But there are 3 others. Based on these graphs, which looks best to you? 1 ohm - 1200 - 1500w amp so 1000w`ish is what I would throw at them.
