I know this has probably been answered multiple times, but I performed a search and couldn't find the answer. I am getting two cabinets - Ampeg PF-210 HE and Ampeg PF-115 HE (please don't turn this into a mixing cabinets thread). They are 450 watts each. Of course always using my ears to make sure I don't overload them, in theory, they should handle 900 watts combined, right? I'm actually planning on getting an Ampeg PF-800. Thanks.
