Here's another very valid approach to the all-in-one speaker. 'All in one' is extreme in this implementation. Each driver in each speaker has its own dac and amplification. What was most apparent during the demo we shared that day, was that these speakers could fill just about any room and were a blast to hear. Huge jump factor and nothing in the sound that would indicate anything but a full range speaker. All you need here is a music account and an ipad or similar and you are set.
