Among the 15" combo offerings, which one would you think has the best qualities to also serve as a small subwoofer for a small PA? I don't mean as in live gig PA, just something you can use for general music on events. I'm thinking I need a solid power amp and I want a cabinet that can take a 15L or 15B if the need arise, and maybe a tweeter than can be turned off. It's OK if thingie is heavy, the objective is to save space. Which also makes me want to avoid dragging around a 19" power amp and a bass preamp.
