hows come?

whole different ball park

Also, I read a forum post (I believe by a TC engineer) that stated low-frequency extension is heavily dependent on Qts and Mms. (the higher the better. He stated Fs doesn't have much to do with it). The TC-2000 has a higher Qts and a higher Mms than the TC-3000.

Unless TC has learned something that no one else is aware of, low end extension is determined primarily by Mms and Cms, both of which are used when calculating Fs.

Fs = [6.28 (Cms * Mms)^0.5]^-1

Wow, thanks for that info. I had never seen that formula before but was always curious as to how Fs was derived mathematically.

What format does Mms and Cms need to be in to get the equation to work properly?

For low end extension is it better to have a higher Mms and a higher Cms?

Fs does not determine real application low end extension. I can take an Fs of 40hz and make it hit 15 linear if the subwoofer is designed to. Its system dependent.

I have pretty much decided on the TC-2000 15" DVC, now I just need to figure out the optimal box size for it.

lol. fs does not determine lowend.

It does not definitively determine lowend, as this is fairly enclosure dependent, but it is a factor, moreso in a sealed enclosure.
