Although I'm not the hugest fan of Mackie's top cabs, I got to give a pretty ringing endorsement of their subs. I have the 15" self powered type, and it has been bulletproof. As a balance to our JBL SRX 12" top cabs, it works like a dream, from quiet intimate places to very large outdoor venues at full bore.

For me, the trick is not to have the smallest, lightest sub (and PA) for a particular venue, it's having ONE that can work for ANY venue, ANY volume level. I don't feel like buying two or three PA's to cover diverse gigs. Just get ONE that can cover it all...

If all you ever do is background gigs, sure, use whatever. No-one cares. But play outdoors for a thousand or so (that wanna PARTY, not talk over the top of you!), and that Logitech is gonna blow so fast you won't have time to think!
