Re-using a PA cab

[vsmith1]

I have a plastic enclosure with a tweeter and a 12" driver. It used to have a pair of amps, but they went and I have removed them. It was part of a small PA system as one of the active speakers.

So my (potentially dumb) question:

Could (should) I re-use them as a bass cab? I note that that the tweeter has an impedance of 2.5ohms and the 12" driver is 8ohms. Which means either I ignore the tweeter or have to do something (?) to make the overall impedance either 4 or 8 ohms. I have a simple passive crossover that replaces the gubbins I had to remove.

At present, I use a Line 6 Studio 110 as basically a stage monitor as the output goes into the main PA. But I'm thinking that I might get a rig of a head and cab, as I find the 110 a bit quiet as a monitor (to get over our drummer and guitarist). So in spreading out the expense, I thought of getting a head first and using it with this enclosure. Then getting a either a 1x15 or 2x10 cab as the next step.

Comments, suggestions, recommendations?

Thanks
