Brought home the the 502a-502b system today, and I don't know whether its just because its now stereo, but these blow the single L1 away in my view. Each side runs 5 4/12" drivers (the 802 apparently uses 8 and I think they are 5") and the 502b sub is very tight with really solid bottom end.

Its a bit more setting up, eg 2 power amps with the controller, but the sound is well worth it.

I priced this same setup with a Bose dealer yesterday and I would not have got much change from $6500. This system (used 30 times by an original folk band), $2000...As the Bose tech I spoke to said "...you're in front before you even start..."

Now I can play some of those wonderful stereo piano samples again.. happy days
