I'm about to get 2 B115e's next month. I'll be pushing them with an Ampeg PF500. Anyone know how hard they can pushed? Will they blow out easily? Should I get some backup Eminence speakers just in case? lol. The Ampeg site says they should be paired with a Portaflex 350 or 500 but I'm afraid if I get too loud with those 200watt speakers I'll trash em. Anybody have the B115e?
