I have found the 21LW1400 to be completely badass.

Increase the sweep until the woofers max out and regraph.
(if your neighbors will even let you).

I'd like to see which one cries uncle first and at what SPL.

How high was the noise floor while taking these measurements?

The amp tripped a couple of times when starting at 10hz. I didn't test with a KLR, I may do so next run.

There was a slight breeze, the SPL meter wavered between 20 and 30db when I wasn't doing sweeps. Not much I could do about Mother Nature unfortunately.

Which amp was that? (oh Ashly FTX-2001, nevermind)

Be careful doing 10hz on a ~30hz tuned port; I'd start at 200hz and sweep down to 30hz or so. Problem solved.

It is light, output that keeps up with the B&C, and isn't god awful expensive. It also measures the flattest of the bunch in the 2 cabinets it fits.
