You would be suprised at the different materials conventional speaker cones are made from. You've probably seen plastic and paper cones. Probably even a few different types of plastics.
Speaker cones have to low resonance or at least a very narrow frequency range they resonate in. With a narrow resonating range, you can just put a low-pass/high-pass filter on it so it never receives the resonating frequencies - they get sent to another speaker with a different resonant frequency.
Metal tweeters have become very popular recently. Any really light, but tough metal is good. Alumin(i)um and titanium are the most commonly used, but there are some more exotic ones like Focal/JMLabs beryllium tweeters. The problem with metal cones is that they act like tuning forks - a really narrow resonant frequency range, but if they hit it they really resonate. My B&W 603s have aluminium woofers - which I just love the sound of. They cut them off pretty low though.
Kevlar (yes, the bullet proof vest material) is also a popular material at the moment. B&W and Wharfdale are two companies that make Kevlar based drivers. B&W have some interesting documents on their web site on what makes it such a good material.
Wooden cones would have a nice wide frequency range. Think about how wood sounds when you knock it with your knuckles - a nice dull thud. Yes, I'm ignoring all the musical instruments made of wood. I'm talking about your normal block of wood. They already make the vast majority of speaker cabinets out of wood precisely for the low-resonant properties that it exhibits.
A "braaagh" eh? Sounds like you need to stop touching the blades as they spin around. And for the "fhwhhhh", I can recommend realigning the PC into a different magnetic field. Try turning it 30 degrees clockwise.
Some people think you're right. Does anyone remember this incident? If I remember correctly he believed that the black bands displayed when watching widescreen movies in 4:3 aspect ratio were being used to send hidden messages.
Satan: So what makes you think you'd be good here.
Canidate: Well, I think this position is a stepping stone in my chosen career path.
Satan: Do you have any sadistic or psychopathic tendancies, a hatred for other people or a business degree?
Canidate: Well I have a law degree and a couple of years working at SCO under my belt.
Satan: Well why didn't you say so? When can you start?
I'm picturing McBride's PC flashing up a little Outlook calender entry 'Today: Sue Linux user'. I guess we find out if he hits 'Dismiss' or 'Snooze'.:-)
I'm not talking about the gateway/circuit city peice of shit that has EDTV resolution
Well we Aussies get a really raw deal with plasmas. PAL (which we use here) has a resolution of 576 lines. But the cheaper plasmas (around AUS$6000.00), have NTSC resolution (480 lines). So these massively expensive screens have *less* resolution than any pokey little box that Tandy will sell. It's not good. By comparison, $6000 will get you a damn fine screen using any other technology. You add about $2000 to get proper PAL resolution and above.
These spoilt young hooligans! Back in the day when I coded CFD, we used 4-bit processors and strung them together by the serial port to make the necessary precision. Even then, it was in integers so we had to work out the decimal places by hand and type them on the end!
So the story underwent a bit of editing. Here's the original:
I'm a seller for a group of drug dealers. We often get our tip-offs by listening to the police scanner. Unfortunately, it's sometimes difficult to understand the street address that the police dispatcher is saying, or sometimes s/he mentions the address before giving an indication that a bust is going to happen. Does anyone know of an alternative early warning system (cheaper than bribing cops) that will help?
Firstly, I don't work there anymore. Secondly, the employees have worked on OSS on company time. So the company uses OSS and contributes back. Sure, the main product isn't open source, but they have contributed back, and everyone has to make a dollar.
The first time I came across Nullsoft was mucking around in Plush. I was getting into 3D graphics, and plush really belted along on my Power Mac 6100/60. And what's this... source code!
I've written the graphics engine for a 3D visualisation package since then. The sharing of source code benefits the world.
If I ruled the world, I would create a multi-paradigm (object-oriented, generic, functional, and modular support) strongly-typed low-level language that let you program at a high-level.
And if I ruled the world, me and Salma Hayek would... I'm sorry, what was the question?
Well here is the story of retiree Ernest Brenot, 79, of Ridgefield, Washington. He doesn't own a computer, nor does he know how to use one. The RIAA claims he likes Vanilla Ice, U2, Creed, Linkin Park and Guns N' Roses.
Where the hell do they get these lists from? They can't have got something like that from ISP records.
Assuredly SCO has given ample evidece of being blindingly incompetent in the past, such that sheer incompetence is hands-down the most plausible explanation here.
And what we're all waiting to hear, is if they've been criminally incompetent.
At a government department I did 5 weeks work in (around 500 people), they got in a new projector. The lense cap was quite dark, but when a projector shone through it, you could just make out the image. After the first 5 people came back complaining about the terrible image quality, they ended up printing a big sign and attached it to the inside of the case reminding people to take the lense cap off. You wouldn't think it would happen in this day and age would you?

Well, yes. But you have to pass it through a couple of filters, auto-pitch-tune it and slap a barely dressed teenager into a film clip.

This is interesting news in the world of hi-fi.

Or maybe just give it a good hard whack.
Philips is watching us, man.

Why is David Becker being hunted down?
Maybe someone's jealous of Posh Spice?
If business or law, go to hell.

All of the above? Or has CowboyNeal been busy buying stock and winning German elections?

I see I'm too late for the Simpsons reference. Maybe I could get in an 'Overlords' joke. Oooh, oooh, what about a SkyNet pun?
It's all too easy.

No "12" is just fine. "12" is the number that's missing. Hang on...

They had a nice surround sound system in Radio Shack? creepy... :-P

I think SCO is misunderestimating the tolerance for stupid circus antics from big business overseas.
I think you'll find they're misunderestimafying. Yes I'm being a smart-ass.
Hey... Aren't you the guy who tried to sell me the Acoustic Enhancement Rock with my speakers?

Why don't I hammer together all of my digital manga collection and call it the first 10 Gigapixel scanner image?
Forget that! I'm going to stitch together my porn collection for the first 100 Gigapixel orgy!!!

I feel sorry for the poor kid who'll never be concieved.
Would you really consider this person bringing a child into the world?
Looking back at the sites I've seen that use Zope, all of them are using Plone as well. I guess that's more what I had in mind when I first posted.
