Hi guys. As title says.. Thinking of building X4 of these loaded with nlw9600 powered by k20. My question is on the plan and processor settings it says  High pass: Butterworth 2nd order, 12dB/Oct @ 25 Hz.. Isn't 25hz a little low for this cab? Heard these cabs in action and they were brutal but was more 40hz+. Can this cabinet actually reach down to 30hz no problem/ease? I'm asking here because we all know what manafacturer specs are like Wink and seeing as I haven't got acess to these to test.. Anyone put these through their paces with hfp set at 30hz and flat out in heavy sub?  Cheers

K20 will not sufficiently power 4x of these, despite the spec.

Look at getting an X4L
