It's a great cab.
It's an impressive cab. I would have paid a hundred bucks more for the Aguilar I tried out, not double like it was marked for. The Hartke is also a good size. Two stacked will be the height of an 810. It'll be nice having it closer to my ear.
Aguilar is like Mesa where you pay lot just for the name. $100 worth of actually better and the rest for the label seems about right.
Although the DB750 was one hell of an amp. Those things sound monstrous. Still not paying double the price of a GK though.
