For those who have Compacts, you know that there is virtually only one way to set up an additional speaker/sub. My guess is the rest of you are just guessing. The Compact is a very simple in/out PA with very few (but useful) options.

I think we need to clarify if Shiju is going for two Compacts or two L1. He said two different things in two posts. The L1's, obviously, can have many B1 subs added to them. Compacts are restricted to a stereo RCA out. B-1 subs are not compatible with Compacts.
