I have honestly never thought about speaker size when buying guitar cabs and have just gone with how the cab sounds and performs. I know that amongst bass players there seems to be a strong preference on speaker size with some staunch advocates for 10, 12 or 15" speakers. I'm thinking of getting rid of my heavy guitar combos and going for a separate head and speaker but something smaller but still with a great powerful sound. Is there any real life on stage benefit tone wise between 10 and 12" speakers these days. Not so much between manufacturers but just in terms of the speaker size as I'm hoping that there is a lightweight solution.
