Hartke XL 410 with a low B string?
 

I have no experience with these but an opportunity has come up to nab one at £300 and I'm tempted to take it. I'm playing through and Ampeg SVT 7 pro with a 5 string bass. How are the Hartke XL 410's at handling those low tones?

I would say, not good at all. I managed to have two of the aluminum cones crack with standard 4 string use.
extremely disappointing cab imo, mines been rotting in storage for years.

Eh, thanks for your help, I'll keep looking
