Hi there. new member here. I’ve just come into possession of some mk1 Wizards and have been scouring this forum and the rest of the internet for info. I was wondering if anyone could tell me the nom impedance of them? I see the mk2 is 4ohms and assume the mk1s are the same. also, related question; my amp (Yamaha rx396) states when running 1 set of speakers they have to be 8ohm min. And if you want to run both sets they must be 16min. I have been running the wizards through this amp and they sound great. But I haven’t really pushed them. Am I likely to damage them if they are indeed 4 ohm? thanks in advance. james.
