Jensen C15k Midbass in OB?

[InclinedPlane]

http://jensentone.com/c15k.php
I've been looking at this guitar speaker for possibly mating with an 8" fullrange driver like my Audio Nirvanas in open baffle 2ft by 4 ft.

*I'll be covering 100hz and down by an active woofer
*I'll be covering in the neighborhood of 250 hz and up with the fullrange driver (or wherever the baffle dictates the rolloff)

With this narrow frequency target, this guitar speaker looks ideal.

The AN is 96db and the Jensen is over 100 in the 100-200 hz area.
Yes, the Xmax is 1mm but I don't need bass, just midbass. I've run the AN loud and unfiltered and its 1mm is no problem on heavy bass passages. In fact, I would just cut the Jensen's high end out and let its low end do what it wants (as miniscule as that would be.)

Look at that nice high Q - almost .9
And look at that moving mass - 43g for a 15" driver!
Price is reasonable.

Thoughts? Problems?
