Apple Today Samsung AV product lead Chris Moseley had comments about Apple's rumored entrance into the television marketplace that sound eerily similar to that which Palm CEO Ed Colligan's said a few years back about how Apple's ability to simply walk into this market and figure it out like they had managed to do after years of research.

Sound and sound quality is not about moving lots of air. Sound quality is determined by the drivers ability to accurately reproduce frequencies. And no speaker does magic tricks -- in other words,... crap in, crap out.

You have to agree that current speaker designs need to be of a certain size (among other things) to render basses properly, though. Which is one of the reasons why bundled speakers in current laptops, TVs, and cellphones are doomed to suck from a sound quality point of view.

As a very general comment, yes bigger speakers have typically been needed to produce accurate bass frequencies. That's not a given though as you can easily have higher quality bass response from smaller (rather than larger) sized speakers. There are a few new designs on the horizon that will reduce it much further with better response.

When you're referring to ultra-small speakers, such as those found in cellphones and laptops... Yes, physical size limitation has an impact on the speakers ability to perform accurately. In other words, quality will always be an issue when you've scaled down that far thanks to physics.

There have indeed been new speaker designs trying to get around this issue for some time (e.g. Altec's designs that use the desk as a mid-range speaker or subwoofer), but sadly they have yet to reach widespread adoption. Maybe current small speakers are "good enough" for too many customers...

On a merrier note, a friend of mine who studies acoustics told me that researchers have fun generating audible sounds at specific points of space by making two out of phase ultrasound waves interfere. It still remains to be seen whether this approach can work at a low cost and with several moving users, though.

Indeed. I wish someone explained me once how headphones and intra-auricular earphones manage to get excellent frequency response with their ridiculously small drivers though : is the problem of small speakers one of higher sound intensities or larger distance between the listener and the emitter ?

Maybe a better place for woofer is in a separate box, like many ~PC speaker sets do for a long time. Maybe integrated with the power supply unit, for "tidiness" - yeah, possible interference would have to be taken care of, but it shouldn't be too hard generally: for one, I don't think modern LED-backlit TVs need any high voltages anymore.
The screens themselves will only get thinner ...TVs seem to be also about size (also thinness) / sexiness? (yeah, Apple could do good)

Either way, as you say in other post, people are generally satisfied (also about so called "HD" http://www.osnews.com/permalink?508052 )

BTW what you mention nearby: maybe it's better to not give the tool of such interference to ~filmmakers - infrasounds (easy to obtain in such setup, even not-quite-on-purpose) tend to work weird on humans, some "bad" mental states would skyrocket, together with ghost apparitions and such ;) (especially considering how TV is an evening thing, when we're tired, with more propensity for brainfarts)
And yeah, I'd also guess the two problems you mention with small headphones - sound energy should fall with ^3 after all (and maybe it's even better for headphones, comparably - after all, they work in a sort of tunnel)
