I have a new GK 700RB (Series 1, 380w @ 4 ohms, 230w @ 8 ohms) and two fresh Aggie GS112s. The G-K just came from the shop after being DOA when new - a simple internal fuse swap fixed it - and it checked out fine on the bench. I spent a fair amount of time dialing in a tone with both cabs hooked up to the amp through 1/4" 16 ga cables. I got a good tone, but was less than impressed with the volume (volume at 12 o'clock, boost 1, master 3, woofer high cut engaged, treble 11, mids 1, bass 2, contour "off", presence 9 - my Am Dlx J was set flat except a little bass boost). When I unhooked one cab, the sound was altogether different - MUCH deeper sounding and it almost seemed louder as a result. This was with the master dialed back to 1. I tried each cab independently, and also swapped speaker cables to ensure everything was "consistent", and it was. My conclusion is that 230w starts to make the Aggie sing, while 190w just doesn't get you there, even X 2. But it is counter-intuitive that a 40w difference seems to be huge in terms of the bottom of the GS112. I have heard people who drive a GS112 with a Clarus (120w @ 8 ohms?) and report that it rocks. Does anyone have this same rig, or have a similar experience with one versus two GS112 cabs? Do I simply need more power to benefit from the two GS112 stack, or could my 700RB have some sort of issue? Any advice or experience to share would be much appreciated.
