OK, so, briefly:
2xML112 vs 12/6/1=12sub vs 2xGK Neo 112II
They're not as different as you'd think...the stacks (and individual cabs) are nearly identically sized. The GK's feel like "the light-weight" winner, but, I didn't weigh them. All 3 of these stacks do what they do beautifully, and I've gigged all of them with lud bands in big rooms with no PA, with no problems, at all. They do "present" a little different from each other.
The GK's are lean by nature, but will take bass eq well. Their horns are bright-overly so at any level above 9 oclock-and can be kinda harsh.
But they have attenuators, so set the balance where you like it
They're mix shredders by nature. No mud, no blur, cutting mids and highs, and present a pretty nice balance of bass thru highs if you have the attenuators set right.
The GK's have never felt stressed under the MBFusion, or 1001RB, but hook up the M9 to them, and they feel like they wouldn't like a long term beating from that head.
12/6/1+12sub
Big native lows, that can be a bit much in some clubs. You can eq that out, but, they retain that in their nature. They hammer with the kick drum, rather than above it. The 18Sound mids can be a bit harsh. The horn is high ranging and airy/smooth, versus the GK's somewhat harsh presentation.
If you like paper cone drivers being pushed, these are free of that...I miss that with these cabs, but that's a personal thing.
You can dog whip these to death, and they just don't even flinch.
ML112's
These pretty much slot nicely between the two.
The lows remain tight and focused..maybe there's a tad more native heft than the GK's, but maybe not.
The mids are very present, but in an easier, smoother, more musical way.
The ''mid drivers'' present a lot more content than you'd think, but in a more vintage feel than the other two. Treble content goes high enough, and bright enough to satisfy slappers, and those who want an edgy tone.
Mids are very present, and these cabs are as easily heard in a dense mix as the GK's, despite they're more laid back delivery.
The mid drivers don't give under stress, and do wonderful things with grit/OD.
They take bass eq well, and deliver nice meaty bass. They're not in the "line up with the kick drum" vein the 12/6/1 stuff is, but, no worries, you can dial in more than plenty of fat.
I haven't felt them complain, but they're not mine, so I don't feel "licensed to dog whip them as if they were," but, they don't feel "flinchy" like the GK's did under the M9. I haven't tried the M9 with these, and I will, but I don't think they're gonna care much; they didn't mind the 1001RBII in the least.
For me, and **my personal sonic goals!!!!** this is a two way tie between GK and Baer.
The 12/6/1 rig just doesn't feel as mid rich as the other two, and it's mid delivery isn't my personal fave. The lows can be a bit much, but, if you want a sledgehammer you can beat on unrelentingly, they're really good.
I've been gigging the GK stack for 18 months or so, and love it a lot. The highs can present harsly, but you can set attenuators and eq and then there's no worries. They're a great match to the GK heads I pri9marily use. They don't like the M9
The Baers are warmer, richer, and still plenty bright, are built to a higher level of quality than the GK's both in terms of "pretty," and just fit and finish and feel. They have eye candy appeal. They certainly feel like sturdy long term partners, and as long as "you can live without that last bit of top end, and live without the feel of a horn," they don't give up anything to either stack. The Baers seem to take eq, and various basses really well. The GK stuff "still sounds GK," and the 12/6/1 stuff always sounds like they sound...the Baers, well, they can be various things, under various amps and various basses. Neato, like that.
hth those who ask for comparision;
