Per the above two posts, a Walter Woods with the GS112's would not be my idea of a good time. I've been there and done that for about a day, and it was a long day
I did a brief comparison of my DB112 x 2 stack with the S212 (using the Puma500 and my Sadowsky MV5), per a PM request from a fellow TBer. I though I'd post a picture and my brief impressions, since the S212 is actually lighter than a single DB112.
I was quite surprised. The S212 MORE than held its own, and actually seemed to have noticeably higher SPL (louder at the same setting than the DB112). The DB's did have a touch more low end extension (remember, the DB's use the same drivers as the GS112, and have that same big low end, with a touch more mid punch), but the S212 had more low mid punch, and also a much more present upper mid response (more modern and a bit more growly).
Volume-wise and ooomph wise, they were comparable, although I preferred the more modern top end of the S212. The DB112's have a very nice mid-mid punch, but there is a bit of a hole between the upper end of the driver and when the tweeter kicks in (not as bad as with the GS112, but it's still there). The S212 is totally seemless in the upper mid to treble transition, and with the very powerful tweeter control (volume and crossover frequency), there is a lot of tonal variety in the upper end of the S212.
All in all, I was somewhat surprised at this comparison, especially the SPL/volume results. The S212 really wumps.
It also reinforced my earlier description of the S212 being more like a really loud 210 cab than a more traditional sounding 212 voicing. It is tight, crisp, and punchy, and has a very, very 'quick' feel to it.
This cab, and the new Schroeder 115L+ are, IMO at the top of the heap for extreme lighweight single cab solutions (4ohms) when using small monoblock SS heads.
