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.
While only trying a cab for a short time in a bad room is not a good way to evaluate it, and putting any cab in a corner can result in some issues, the rear porting would have VERY little impact on this. Port location really makes very little difference.
If you dig your UL210, then the thing to do is get a second one for more volume. However, as you say, there is a bit upper mid dip in the UL cabs, and especially in the UL210, so grind they don't.
Some of the Markbass cabs are OK, but avoid any models that have the piezo tweeters. Bad news (both tonally and reliability). The models with the compression tweeter are quite good.
