A few random thoughts. The players were Monique/Minnie, GK MB Fusion (500), Mesa Walkabout, H1203 (single and pair), TC1120-8, and the Barefaced cab. I was playing my Fodera YYD, and Adam brought his very cool Nash P-bass - which reminded me that I dig a good passive P. The H1203 is kind of an ideal middle ground cabinet, and the pair just flat out sounds awesome. It has a 3D quality, is articulate, never gets harsh/nasty, and the tone is open yet well supported all the way through. Combining the TC with the H1203 adds a fair amount of lows and you lose a bit of the mid punch. With Monique you don't get a ton of sizzle/highs so switching to the TC doesn't really change that aspect that much. With the GK there is a bit more going on up high, but it can get a little edgy - to me that is a GK thing.
The Barefaced is a totally different beast. By comparison it sounded rather 2D and a little veiled. It doesn't extend high, but you've only got the 12" so not unexpected. It does put out a lot of low end for its size, and while it isn't the tone I go for, I'm betting that in a mix with a rock band it would work quite well. For smooth jazz or R&B, less so. It gets loud for its size/weight, and is a nice form factor for fitting on stage (shallow from front to back). The Mesa is a bit of another beast as well as it isn't a particularly "open" sounding head. But again, for the rock thing, I can see why guys dig it.
Bottom line is that it is hard to fault the H1203 pair. Gets the tone I want, is small/light, one cab will cover a lot of gigs, and the pair will tear paint off the walls if need be. The TC112/H1203 is an interesting combo as well. Bigger low end support, less edge in the upper mids. I think the H1203 pair is more my sound, but I could see some people preferring the TC/Hathor combo or just TCs.
