There's a How It's Made episode about speaker drivers somewhere on YouTube if you're interested in learning how it's really done. It was filmed at the Canadian pro audio manufacturer Belisle Acoustics, who makes their own drivers for their "Transparence" brand of pro audio speakers.
Some Bose models have their place. Recently when the Bose Acoustimass 3 speakers came down in price to $200, I bought a set as a curiosity - I suspect there may be rooms in my house where my wife won't let me put big floorstanders or massive standmounts, so I figure I'll be able to find a place for them. They're decidedly mid-fi, but not entirely unsatisfying. The Acoustimass 3 speakers don't do that direct-reflecting business, so they don't suffer from as much of that transient smear in the midrange and treble. Also without the direct/reflecting jazz, the single-cube speakers seem to produce the same sort of amazing stereo imaging that single-driver speakers are capable of. They do need a beefy receiver to drive them, though. I also have a set of Bose 141 speakers that I bought on eBay for my garage - they can take a pounding. I'm by no means a Bose apologist, but I'm just saying I've found applications where they can do decently. From a technical standpoint, though, I'm in agreement that there are very few Bose products worth buying.
One serious problem with Intellexual's report on the Acoustimass (which only covers Series II Acoustimass 15 systems), is that he doesn't take into account the summed response of the system. The 'hole' between 200 and 280 Hz is filled mostly by the cube speakers, and somewhat by the bass module. Now, the fact that the bass module operates up into this range makes it very placement-sensitive (firing across the front wall seems to work best), and it causes the midbass to sound slurred sometimes, but the accusation that there's a hole in the frequency response there just doesn't hold water.
