Hey,

In an open back cab would this speaker

Eminence Patriot Texas Heat 12"

http://www.guitarcenter.com/Eminence-Patriot-Texas-Heat-12--150W-Guitar-Speaker-660031-i1153600.gc

Sound decent in a 2x12 through a mesa lonestar head?

I'm playing this -> http://www.soundclick.com/bands/page_songInfo.cfm?bandID=671284&songID=7191551

If not would anyone recommend a decent speaker that wont break the bank?

Also, anyone know where to find the standard 1/4" jack that most amps have on their back?
