I went with the additional GS112(s) for modularity...bring what I need and nothing more. As has been stated on TB many times, a second GS112 (or NT) adds WAY more than one would suspect. Although I have four of them, I have only used all of them once. Honestly, two have given me all that was needed for any club/bar gig I have done. Anything larger, or outdoors and I'm in the PA. Interestingly, when I first auditioned the GS112, I was using Peavey 410TXs and I did the old informal living room test...side by side, one GS112 gave me all of the volume and low end of the 410TX (admittedly nowhere near the most efficient 410 out there...but not bad, either). My back shed nary a tear to see the 410s leave. The GS112s were one of the first standalone 12s out there that had serious bottom in a relatively compact form. Now, there are many...most of which are reportedly a lot livelier in the mids than the GS112s, but mine have become like an old friend...they suit my (lack of) style and sensibility...and they give me the sound that is in my head...now, if they could only magically correct all those flubbed notes...
