adding a sub

[woody357]

This my question. I have a four piece band, bass drums keys and a singer. I want to know if a 15 sub would be good enought to add to my pa, a Bose L1 1S with the 2x10 bass mod. I wanted to know if I added 15" powers sub to it would that be enough to give my band a bigger sound. We don't play real loud, but I was thinking the added sub would help with the overall sound. I know. 18" sub would do the job, but I'm trying to stay lite. We play R&B, Smooth Jazz,

Never heard one. What's the 210 option? If it's a sub it might be well balanced to the rest and all you might achieve is a silly boom with a bigger one.
