Re: RL-p18 with a Linkwitz Transform... good, bad, or ugly?

Just been fiddling with some calculations, and keep in mind I'm still new to the technical stuff regarding LTs, but it SEEMS fairly straightforward so far. I'll attach the file I was working with, maybe I'm way way off on something.

Using the RL-p18 (dual 4 ohm) parameters off the website, I got a response that is down about 3.88dB at 10Hz in a 210L enclosure, using a Q of 8.0 which is a bit high I think, but it gave a significant bump in the low end extension. Also, I know there's a significant amount of boost being applied, should I try to stay closer to 10dB? What other programs should I be looking at modeling this in?

*edit: See my post below for the zipped Excel file.
