I'm killing this track right now,SPL meter shows peaks at 139 db & I'm only pushing about 120 watts of the 2kw triamping my front mains,I can drive peaks over 150 db if I throw all 2,000 watts at 8 ohms thru the mains but I have to lay down after a song or two & catch me breath .
I'm rocking this ELP masterpiece out of this system .
