Last night's hit - this is about as close I'll ever get to the "sound in my head" (as opposed to the voices in my head). Plus I could life the cab in my post-surgery state

That's pretty much the sound in my head too. Thanks for recording and posting this!!
Did anyone go to the Northwest GTG show? I spoke with Duke a while back and he mentioned he was going to send a new prototype of the 10" cabinet he had designed. I'm very interested in that one for sure. If anyone tried it or played it I would be interested.
The 110 didn't get finished in time because I made a mistake. And maybe that's just as well...
You see, I haven't been totally happy with the frequency response of the Kappalite 3010LF for this role, but there really is no off-the-shelf 10" woofer that combines the frequency response I'd want with a motor that comes anywhere near that Kappalite motor. So...
I'm looking into the possibility of having a custom 10" Kappalite variant made. If I go that route, it will of course add to the delay before the 110 is launched, sorry about that. But as I get older, I'm less inclined to spend my time working on things that I have reservations about.
I got to play with the new 1863 Quite a bit. It is a glorious cab! Massive air mover, too. I had all four ports plugged and it was rattling the entire brewery when I was palm muting! The mids are fantastic, and the top end extension is impressive given that it has two 3" cone drivers. In fact, A/B'ing with Charlies TC112, I didn't miss anything on the top end.
Thank you SO MUCH!! It was a very interesting cab from a designer's standpoint. More trial-and-error than normal went into the crossover design, because what I was hearing didn't precisely track what my measurements seemed to be saying.
One of the things I worked on was getting good lower midrange out of that 6" cone mid. You probably notice this detail, but all of the openings in that open-format mid chamber are the same size. This is because they are all actually ports, and are tuning that mid chamber such that the midrange driver has good lower mids along with adequate thermal and mechanical power handling to keep up with that 1200 watt woofer. So a fair amount of engineering went into that part of the design.
The voicing switches also give a lot of options. Somehow Duke was able to make the 18Sound mid usable... in dukes you could have it either aggressive or smooth (via switch), but never did I find it harsh or overbearing.
According to my measurements, that 18Sound mid has a 9 dB(!) peak just north of 4 kHz. That's a really big peak in what is imo a really bad place, for two reasons: First, that's right about where our ears are the most sensitive; and second, that's right smack in the region that belongs to the electric guitars. BUT, that mid has the best combination of power handling and efficiency of anything in its size ballpark, by a fairly big margin (according to the math, it has more output capability than the two 5" mids in the 1855). So I made sure that peak was adequately suppressed, as it's in a really bad place for my "zig where the guitars zag" approach.
More output than a 4x10, it could hold its own against the monster fearful and an SVT stack near by, and you could get almost as clean as a TC series cab, but if you needed an aggressive mid to cut through a thick mix, it could do that, too.
Very glad to hear that both of those voicings worked for you. That's what I was hoping for of course, but until someone else hears it too, I'm never really sure.
I heard a similarity to my Bergantino HD112 with tweeter flat on Sunday; I should of wrote down position the AK1863 switches or ports open/closed when that happened.
Well obviously I wasn't there, but my guess on the switches is, top switch UP (highs to about 12 kHz), bottom switch DOWN (upper mids smoothed out). On the ports, my guess is that at least some of them were plugged.
