Well, yeah - I'm a bit of an audiophile myself, having worked with pro
recording equipment in the past. Nothing in a laptop comes close - most
frequently, it's low bass response that kills the sound. But my T42p has
its speakers mounted on the front edge, and it does seem to do better
than most other laptops - but if I want really good sound, of course,
I'll hook it up to my stereo. ;-)

Well, it's his money. ;-)

I believe the original page is gone, but no, it did not. :-) It used one
of those plug-in drop-in-your-mug coils.

Yes, to produce hi-fi quality sound you need a speaker cone bigger than most
laptops and a very carefully designed enclosure to produce a nice response.

Exactly - I suspect that most laptop design companies don't even employee a
single audio engineer to optimise these things. Or maybe they do, but they
get given a space of 2cm3 and a budget of 25c per laptop.

Right. That sounds more authoritative coming from an engineer...
Actually, as I've mentioned, I just bought some external speakers, and
they produce an impressive amount of bass. But only if your head is less
than a few feet away. The sound seems to drop off very rapidly with
distance - an effect my 8-inch Warfdales don't seem to have.
I notice that these speaker units are *very* heavy for such tiny
objects. Is this significant?

I have Enya's Exile playing at the moment and, with the laptop's volume at
max I can clearly hear the words 2 rooms away.
Note that this is a 17" laptop and the speaker runs across the entire width
of the laptop, above the keyboard. It's not 2 tiny little speakers set at
the bottom.
It's not going to rival the desktop's speaker system, or the new TV for
volume, both which can be heard 2 floors down at medium volume.

You have to take into account the power output of the amplifier (PC or
stereo) and the sensitivity of the speakers. Google it.

Yes the density of the speaker enclosures enhances the baffling in
modern designs.

I think you'll find that "sensitivity" is a measure of how much sonic
power a speaker generates for a given amount of electrical power. It has
nothing to do with distance dissapation...

I was thinking more that being heavy allows the speakers to generate low
frequencies more easily. (Otherwise the driver might end up just
wiggling the cone one way and the casing the other way, and not
producing much sound.)

Yes, the cabinet should be as stiff as possible (unless you have designed
some uber leet flexible cabinet that does very clever stuff). But the
weight you are feeling is probably just the magnet and coil inside the
speaker driver. Do the speakers also contain a PSU and amp? That would
also add significantly to the weight of PC speakers.
