Axiom Home Page Forums General Discussion The Water Cooler Speaker colour have to match the sub?

If your using external power most sub company recommendations suggest double the speakers rating. M80 {60 or 70}. The newer SVS Merlin guide recommends 50. For M80 and larger

If only with the Denon 80 would be safer for AVR power limitations. But you'll probably have more fun playing to find your own preference. Just check from time to time it's not getting to hot pushing the extra power.
