I have one of these systems and use it quite a lot of times in weddings. The old original LUCAS, I mean, not this refined version of it. It's good and IMO an excellent value for the money. However it's heavy. The 15' sub wih all the electronics inside (the satellites are passive) is 35 Kgs, with wheels, fortunately.

I tried the Kustom and didn't like it. For 100 bucks more there's a much better alternative, the Yamaha StagePAS.
