I've run a Diezel German 412 G12K100 FL cab side-by-side with an UberKab 75/30 with an Anniversary (Bogner) 412 V30 412. Different heads, different volumes.
The G12K100 was the most versatile and neutral sounding - didn't add or subtract anything from the sound. It was f*cking loud as hell but solid as a rock. Heaviest amp out of all three by a smidge. Ridiculously loud and omnidirectional. Best use? Stage. Highest "quality" of build in any cabinet I've seen - period (but there's a surprise at the end of this post).
The 20thA 412 loaded with V30 was very sweet sounding with all but the heaviest of high-gain nonsense; which means, awesome cab because all-gain means shit tone, no cut, and a player reliant on fizz to cover up their bullshit playing. Too much gain turns any serious amp into a toy IMHO. So there you go - quality tone, biggest 412 in dimensions out of the 3, and really nice "reliable and consistent" tone for everything but palm-muted wanking brootz (although it did hold up well to these tones, I just don't personally like them myself - YMMV). Stage or recording - no sweat. Beautiful projection. High quality build in all respects.
UberKab?? Versatile and toneful for all sounds. 2nd heaviest cab out of the bunch just a bit over the oversized Anniversary 412. Loaded with 75/30, it made for a cutting, smooth, fun playing cab; but really opened up with the matched TwinJet and Uberschall Rev.2 due to their inherent bass. It handles bass like a tank. Definitely likes to be cranked so gigging and jamming is my guess - mic'ing it would be a 2 mic affair to be fair, one on a 75, the other on a 30. It's a flamethrower - not sure what else to describe this cab as - it wants an Uberschall on top of it pinned at 3 o'clock delivering sonic napalm
[Not mentioned in this review is Fryette. Check out the D412 and the FB412. They happen to be the lightest 412 cabs I own - but their construction is outstanding, quality of wiring, connections, seams, piping, cloth, backing, wheels - absolutely everything about them is top-notch. Sure sure, people bitch and moan about the P50e speakers, but give them a chance to break in....Steven Fryette really knows what he's doing and the cabs are hands down awesome. Accessible, available, not overpriced, and really well designed. Go ahead and replace the speakers if you need, but you don't need to if you give the P50e's a chance].
Hope this helps or at best, at least confuses you a bit
