Vintage EV speaker question,,,advice asap if poss.

I can get a pair of EV 15TRX speaks with cabinets in good to very good shape, or a pair of EV 15TRXB (which has magnets of half the weight, a little bit more narrow range, etc etc), but the cabinets are super mint...

Both at the same price.....to be driven by Altec style 6550 tube driven monos and maybe a tubed stereo radio as well.....

Any ideas?
