i just recently pickup up a second peavey 410 txf to go along with my original one. the original one i blew my speakers and replaced them with eminence ca-2010 and wired it for 8 ohms. that was fine cause my 115 extension speaker was 8 ohms also and it ran my amp at 4ohms. now this second 410 cab is 4 ohms bringing my 810 to 2.67 ohms. now the manual says it can handle that low of a load(lol) but how reliable is it? can i really push it at shows and not worry about it overheating? or should i find different speakers since matching ohms is the "best" thing to do?
