Instrument cabinet questions


I know this is a little off topic but I didn't know where else to go.

I'm trying to take a high-fi approach to my bass/guitar cabinet. I have a 2x12 cabinet I use primarily for bass guitar. I also use it for guitar in one band. It's a little small 28" x 15" x 14" (approx).

I currently have two Eden 12" speakers in it. I wanted to get a little better efficiency with lower powered tube amps (fender or traynors 40-60 watts). I also wanted more top end since I use it for guitar as well. I play mostly rock at moderate volumes.

Here's my question:

will there be any problems/benifits to using two different drivers in the same cabinet. I was thinking of using an Eminence Alpha-12 (for bass and low zmax) and a Beta-12LT (for top end).

the beta-12lt has slightly better sensitivity (99dB) but much higher zmax (94ohms). It extends to 10khz wich is very appealing.

the cab in already made and there is no room for a tweeter (which I generally don't like to use with bass or guitar...

Any insight into this set-up would be helpful...

thanks
David
