I am looking at a new cabinet, A Dr. Bass 2460 NEO This is 2-12" and a 6" with a horn. Here is the question, I have and do use 8-ohm cabs, a 4-10" and a 1-15" as of recent. That brings me to 4-ohm and it works the GK-400RB just right. So I take these out and bring in the 2460, will I still have the same amount of power/sound/presence? I know my tone will need worked out but I want to remain just as present on stage. I like the idea of one cab, a little less to move and i also have been looking at a LM-II to toss up on top. One other issue is if I want to add a 15" cab 8-ohm, what will I end up with for Omage (is that a word). Thanks!
