Dayton Titanic 10" sub kit vs. other 10" sealed

I've read some good subjective comments about the Dayton Titanic 10" sealed sub on this board and others, but I have yet to see any direct comparison information and was wondering how this kit might stack up against other very traditional 10" sealed subs like the REL Strata III, Rocket UFW-10 or ACI Force.

I may look into picking up a pair of these to fill in the bottom end of my Magnepan 1.6QRs and I'd love to hear some feedback. I'm not really opposed to spending the money on an REL, I just don't see any reason to do so if I can accomplish a similar sound quality with the Dayton.

Thanks in advance for all of your help and suggestions!
