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.
