Fair question.
I'm looking for a cabinet that:
1. accurately reproduces my bass' natural tone
2. who's tone sits well in a small ensemble (duo or trio)
3. does not emphasize any frequencies
Right now I don't need a lot of voulme but if I do in the future, I'd like a cab that'd work well with other cabs in a larger configuration.

Based upon that, I might take the T-112 out of the equation. Of the three, it has what I would call somewhat pronounced low end (particularly around a low E), somewhat scooped upper mids (not across the board, but I hear one or more dips in the midrange), and slightly "more sparkley than real life" highs. All in all, it is a phenomenal cab, and one of the few smaller, singler driver (& tweet) cabs that can reproduce a 5-string to satisfying levels. But, looking at your criteria, it might not be the best option.
I think both the Low B-1 and the Tri 112L have the potential to make you very happy. The ACME would be cheaper, smaller, and lighter. The Accugroove is more efficient, and will move more air. I do find, though, that for the most part, ACME and Accugroove cabs sound like they are from the same general tonal family (full, neutral, smooth, accurate).
At the risk of getting too off-topic, some other cabs that you might want to consider would be the EA Wizzy, Hevos Midget, Bergantino HT112, EA VL-110, Low Down Sound 3-way 1x8 or 1x10.
The Wizzy is a 4 ohm 1x12, and it reigns supreme in the tone per pound category. While not a neo cab, it is extremely light. It is full sounding, and manages to be warm, yet articulate at the same time. EA admits to designing-in some midrange emphasis, but the overall tonal impression is very well balanced, and it certainly would sit well in a small ensemble.
The Hevos Midget gets incredibly loud for a 1x10, and goes very deep. It will do a low B at high volume nearly as well as the T-112. It is very well balanced, and very articulate. It is not warm, though, but is exceptionally clear. May be hard to find on this side of The Pond.
The Bergantino HT112 is a very well-rounded cab. Sweet, musical upper midrange, and one of the best tweeters in the business are its strong point. If a hint of "old school" vibe, with modern clarity, is your cup of tea, the Berg delivers nicely. Very competitive in this group. A single HT112 might not be the best for a loud low B, though.
The EA VL-110 is no longer in production, but it is still worth mentioning. Very accurate, and very well balanced. The midrange is not quite as focused as in the VL-208, but it's still quite good. Deep, tight lows, and smooth highs. Very good cab. It is fairly compact, but somewhat heavy for its size. Slightly inefficient, but not too bad, really.
Don Oats up at Low Down Sound in Ferndale, Michigan (near Detroit), builds some excellent cabs. Two, in particular, that might fit your bill are his 3-way 1x8 and 1x10 cabs. Check out
this thread for more insight. I have also posted on numerous other threads regarding LDS.
Hope this helps, Tom.
