Anybody used these speakers?

So, I'm re-building an old orange (i think) 4x12 cabinet.  I have it all done, and I'm looking for two speakers to match the two I already have.  I have two celestion g12t-75's already.  I want something that will sound good with them.  I was thinking vintage 30's, but they're kinda pricey..  I'm looking for speakers that would give me a nice tight sound, with a lot bass.  I play metal and punk.
