Heads are the amps, cabs are cabs
Unfortunately, it's not that simple. There are so many cabs out there that would go well with it that it's not even funny. Hartke has several themselves. Generally, the cab most chosen by people who need a rig that will take some power and not be too large is a 410. But there are so many cabs out there and most decent ones will work well. Just don't go for the dirt cheapest cabs out there because they almost always suck, and do a little research on any that catch your eye.
