The Bose is getting more and more interesting. As far as the JBL's are concerned, those are more for hanging and flying than a quick setup. I want to know more about the PAS II. $2500 isn't a bad price for that.
with the jbl you need a mixer, amps, and a crossover, not to mention about 90 lbs for one sub and one small 8" two way speaker. With the new Bose if you don't get the tone module you get one input and no tone control so you either need the tone control or a mixer. The retractable legs in the base are a good idea but I hate to see what you have to give up. Basically I think it's a lot more money for the little advantage it offers IMHO.

Gary: Heard the Bose. Held off on getting. Glad I did. The Model II looks much more easy to transport with the lighter base. I hope they or someone comes out with a single case for the Base module and the L1 base. For now I am still using the Logitech 5500. However, as you had suggested, I did replace the center channel with a much beefer speaker. The result is a much improved mid-range.
Mike: I don't think you give up anything. Most of the base on the Model I was for balance.
