What if instead of a speaker with a Qts=1 I use a different Qts??

I found an interesting project; it's a Voigt Pipe, the author says it's "the original concept", meaning it uses a speaker with Fs=45, Qts=1, D=8"
What if I use a speaker with a Qts between .3 and .5???
This is the project:

It has been shown that the classic voigt pipe doesn't work all that well... usually the terminus needs to be restricted much more & the driver offset changed... do a search here or on the FullRange Forum on ML-TQWT

Visit my site, Martin King's site & Bob Brines site. Links can all be found in the Read-Me 1st section of my website.... link below.

This project may work just fine with the driver intended for it, but if you change the driver you change everything.
