The 800 is one foot behind my head right on the back wall. My head is right between the two drivers. The bass out of that thing is liquid, silky and makes me wanna rub myself all over it. It is AWESOME!
I don't care how much Ian thinks the 600 is just as good as the 800. I've got two 600s and four 500s and I'd take one 800 over all those.
I had a grade 10 student listen today who knew nothing about audio systems but she's been playing electric bass for many years. She was astounded with the growling and articulate notes spilling out of that behemoth. She also couldn't believe the stage and imaging she's been missing listening through headphones.
