I was about to say that the 18Sound 112 is my favorite of the 112s, then I realized it's the only one I've heard! I've imagined the others vividly, though.

For my tastes, I'm pretty sure I'd like it more than the Faital... maybe more than the LPT - would be pretty interested in hearing an LPT, and very interested in hearing the newest of the 112s and the 110, though I like my 112 a lot as is. Wonder what a stack of the 110s would sound like, and where such an animal would fall, feel and output-wise, in the Big E lineup and compared to, say, a good 210, 310, 212...
Mike, if you're reading this, have you tried a stack of the 110s? Would they stack vertically, horizontally, or both? I see that the mids on the 110 are mounted on the angled parts of the baffle (if that's the right term - I'm not sure what to call everything on these cabs). One thing I like about my 112, which has the mids similarly mounted, is that I can stand right on top of the thing on a crowded stage and hear everything clearly. The 112 also has the tweet on the upward-facing angle (and, yes, I run that "on" the majority of the time), where the 110 appears to have it face directly forward. The mids would have the bulk of the critical info, I'd think, but I wonder how this cab would do relative to the 112 in the "stand right on top of it" department. It is a smaller cab. Also wonder if you'd recommend elevating or angling the thing up or if on the floor is the preferred mode of operation.
Mike has recommended that I try elevating the Flex stack a bit - I've been too lazy to, though I have elevated the top when I've run that solo. The 112 is happy on the floor.
