Spec sheet shows they are 8 ohm speakers and should be used with a max of 300 watts continuous or 600 watt peak power into 8 ohms. If the amp spec is given at 4 ohms then the power will be 1/2 that rating into these speakers. They are pretty efficient so you might be OK with less if they are used in a less than huge space.
yes,thanks for that.the ev,s are 300 watts each and 8 ohms.so a pair will give me 600 watts at 4 ohms,each side. my amp is a peavey 2600,which gives me 900 watts per side at 4ohms. are my speakers safe at that.
