Markbass New York 804
 

Need some opinions on the markbass new york 804. Also, head recommendations (looking at tube 800)

I have not tried the 804, but if it helps, I run a pair of 604's and they are sound great. I know the MB cabs don't get too much love here but between the sound and size they are solid all the way around. I would imagine that the 804 is as good or better than the 604. Good luck.

Any one else use the 804 here?

For me it's just like the company pitch says a smaller, lighter alternative to a 4x10. No problem at all producing lots of low end...definitely has the typical MB low mid thing going on. I'm using it with a 1x15 for the uber-loud rock gig and by itself for everything else. It's very impressive by itself. Two of them and the Tube 800 (I'm using a TTE 800) would be serious overkill for most situations this side of a sports arena.
