Interesting... I'd like to hear that. The thing that makes the Bose work well isn't internal voodoo.. it's the fact that it's a line array, just like this thing. The Bose EQ does have some nifty aspects, but nothing you can't accomplish with a regular EQ if you know what you're doing (of course, then you're right back in the same pile-o-gear boat... mixers, EQs, etc. etc.).
One thing I notice is that this system appears to be pretty short. The L1 is seven feet tall for a reason... if you stand right in front of it the mids and highs get blocked, just like any speaker. Since it's designed to sit behind you and eliminate the need for monitors, the height allows it to project over your head. Same concept as hoisting regular speakers up on poles.
(edit... I hit the website and it shows that the line array can be pole-mounted. Cool. The price? In the same ballpark as the L1. A pair will set you back $4400 US.)
A note on power... that's a very misleading number. It's about efficiency... dB per watt. A 20-watt fluorescent light bulb is brighter than a 60-watt incandescent. Run a 2000 watt amp through an inefficient cabinet and it won't be as loud as a 1000 watt amp run through a highly efficient cabinet.
The important question is not "how much power?", even though everyone wants to know that number. The pertinent thing to ask is "does it get loud enough for your needs?"
