I agree with pretty much all that has been said, above. With regard to the CxL-112, it does not sound as full to my ears as the Wizzy, though it certainly has a more extended frequency range. They actually sound quite good together, and are in the same general ballpark volume-wise (which somewhat surprised me). The above comments on the Wizzy tone are dead on, and I would add only that it amazes me how it is able to sound both "warm" and "detailed" at the same time. Two Wizzy's are substantially better than 2x1 Wizzy, and still make for a very light, portable rig.
If you simply must have the tweeter, or you want the absolute lowest frequency response, then the CxL-112 definitely has the advantage. Also, if you happen to own an iAMP, the Deep switch seems especially well suited to the CxL-112, and you can leave it engaged and push the heck out of the CxL-112 without it ever complaining. The power handling of this cab is very impressive. As I mentioned, though, the sound is not as full as the Wizzy, and to me its seems like this is a comparative lack of low mids to middle mids. This makes for a scalpel-precise, clear tone, but it may be why some people are using the "H" word.
BTW, the NL-210 sounds somewhat like a cross between these two. It is definitely the warmest of the EA 2x10's, and reminds me of the Wizzy in this regard, but it is more extended in frequency response (though the lows are not quite as subterranean as with some other models). The NL-210 is ridiculously light, as well. It also pairs up wonderfully with the CxL-112.
Hope this helps, Tom.
P.S.
Pound for pound, though, the Wizzy is probably the most impressive cab I have ever heard.
