I tested with my ears the latest version of that L1. Very lightweight. You could plug the top of the column into the base without the other 2 parts. The 3 pieces in the column weigh about 4 pounds.
The sound was exceptional. I played light jazz from my blackberry into the system. The bass was good. They brough out a shure 57 mic and stood 2 feet in front of the unit and there was no feedback!

I suggest they've improved the product, and that you'd have to go with your gear and try it out. The price on the L1 was $999. CDN or about 825USD.
