I was just wondering which you prefer, a 15 and two 10's, or a 4 10 cabinet? Will you really get more low end with the 15? I know the four 10 cabinet is very popular with bass players. I was thinking on gig's where I am just going through the house, I could just use the one 15 cabinet (and not carrying all the extra weight of using both cabinets. With the four 10 cabinet, you are basically stuck with always lugging a heavy bass cabinet every time.
