I have the 4 ohm Ex112. Its an amazing little cabinet, I can't believe it isn't talked about more on here. Do a search, there is at least one or two threads on it that I commented in.
It is NOT a high-volume cabinet. If you plan to fight a drummer with one you should look elsewhere (though you could overcome drums with two of the 8-ohm ones). If you have a low-volume situation, it is clear, flat, sweet sounding, and VERY portable. It is very similarly toned to an EA Whizzy.
I use mine with a GK MB200 microhead for practicing and with my upright for 3 piece jazz combo gigs. Its perfect for coffee-house situations as well as for a pit orchestra or church gig stage monitor. That's what its designed to be, and how it should be used.
It only has one 1/4" jack on the back, which I promptly replaced with a speakon jack for just a few bucks and a few minutes of effort. The plastic corners say "Nemesis", as they are using up left over stock from the discontinued Eden Nemesis line. They are standard plastic corners of good quality, I could care less what they say upon close inspection.
I defy ANYONE to find a better sounding micro-cab at this price point.
