I already have a Mackie SWA1501 for the main PA. Don't really need ANOTHER big, heavy sub.

I'm a little cautious about retasking home audio stuff for pro use. Had a fair bit of it blow up or fart out when brought up to gig volumes, but I'll look into those Best Buy alternatives.

I'd really like something akin to the Bose subs for the L1 system, that's about the form factor and weight point I'm looking for...
