Since one of the primary differences of the AE212 versus the UL210 is a tighter low end and a MUCH more even mid response (i.e., it doesn't have that 'scoop' like the Epi cabs, especially the 210UL's), I would assume you would HATE the even more pronounced mid presence and low end tightness of that particular Markbass cab, the Bag End cabs, and any of the Berg cabs.
If you really dig the 210UL (one of my least favorite cabs due to the big low end, dip in both the low mids an upper mids, and uber hi fi top end), you probably need to stick with that model and get dual 8ohm models IMO.
Wow, IME I found some opposites.
The UL210 has that nice tightness but quite a full bottom for a 210. I have only been using one UL210 btw.
I found the AE212 to be a bit scooped and wooly and some eq meddling didn't seem to sort it much.
I am not blaming the AE212 cab 100% as I moved it on (a little too quickly) even though i played quite a few gigs/jams/rehearsals with it.
Wish i had of kept it for a bit more mucking around with as they are impossible to get now here in Australia.
I know i made a sound mess of things early in the piece by backing the cab too close to a corner and those rear ports fired a low end mess back into the room....
So while i like a single UL210, 2 may get mushy?
I would like some more upper mid grind than i do get with the UL210.
I do like the lighter cabs too, well my buggered back does anyway.
Prob is that where I am, there are no more AE410s/210s/212s and I haven't seen any 2nd hand for sale either. Never see BE here so my choices are coming down to the MB stuff.
I haven't loved their 210s but not hated either.
This is why I posed my orig question of whether anyone had actually tried with the NY804 (or 2 of them)to date.
Cheers,
Mark.
