Wow. Much higher than I'd expected. Good thing I was soliciting opinions otherwise they would have ended up much lower. it just made sense that "ear level" would be ideal.

Finally got all the speaker wire stripped and attached. Trying to figure out where the receiver has to sit and still allow all the cables to reach. The 150 is a monster and taking much more of my top shelf than I expected

My M60's make me listen
My M80's make my ears hear
Either way - I'm not deaf anymore
