I saw behringer 4 10 cab, and a 1 15 cab for 200bucks. I already have 4 10's and wanted to add. What would be better, another 4 10's for 8 10's total, or the 1 15 for 4 10's and 1 15? I don't know what would be better. The band is usually a funk, rock sounding band. I want to sound deep but not so deep as to were the notes sound muddy.
