Many things have come to my mind now, about taking advantage of the Power Amp maximum output on the RL1018 system Im ordering. I have considered the RL1810 Wich has only one 8x10" cabinet. This way i would have to say BI-Amp bye bye, but would take advantage of of the 1000 Watts completely,on the other side, portability is compromised and on small gigs it will be too much. Also, I dont know why but Carvin has not yet released the specs on that cab. SO Im considering now 2 RL410T instead, wich will provide 3dB more in the highs over the RL1018 combination, wich I like.. Full 1000watts advantage, retaining the posibility of using less power/cabs for some venues. The problem is that I play a 6 String bass, and maybe soon a 7 String tuned to LOw F#. Should I stay with the Idea of a 1x18" with 4x10" to have BI-Amp capabilities and a little added low end? Or 2 4x10" Cabs are going to be enough for the low end and I shouldnt even care about BI-Amping? I will greatly apreciate all your comments. Btw. Im sold to the Carvins because of the Quality of other products I have Sold/Used and because they give me a special endorsing program wich gives me a very cool price. Thank.
