I've been playing a single 15" speaker for a traditional sound on surf and classic rock. However, I got tired of having very poor note definition. Too much of the time the bass sounded like 'woof, woof, woof" in the background...and I couldn't really tell the bass notes apart. So last weekend I bought a G-K 4x10. Better note definition, and still a strong low end with plenty of punch. (And I can use both the 4x10 and my single 15 together if I need to.) Who else likes this style of cab - and why?
