Hi, anyone one have experience with the GK 700RB 115 combo? I am looking to add an extension cab to get the max wattage out of my amp which would be 380W and 75W. I am considering a 2X10 or maybe a 1X12. Some brands I have been considering are: Acme, Aguilar, SWR, or GK. Any suggestions or comments would be much appreciated. Thanks.
