"They pulled the grills off the front and inside were a couple of the Bose double cube speakers. It was hilarious."
The folks at Bose certainly knew their audience and were masters at marketing to them.
After spending some quality time with small speakers accompanied by competent subwoofer, I came to the conclusion that the lion's share of the girth and weight of a serious full-range speaker system was the section required to make bass. Thus, my observation that if you took a large, full-range speaker, took a chain saw to it and removed the mid/high section, that mid/high section would have been fairly small. So, sub/sats can be a legitimate approach to high fidelity. Ultimately, there are physical limitations if the goals are pretty lofty (and, expensive), but for the most part if your "sats" can produce adequate energy to below, say, 80 Hz, you've got something real to work with.
