Maddest Loud Speaker ever?

[Shoonay]

You guys, please don't confuse the frequency range of the human ear hearing range, with the quality of the sampling rate's frequency of today's digital devices.

We can hear something from 20Hz to 20000Hz (20kHz).
Sure, below 40Hz we can "feel" or see the speaker moving rather then hear anything, and everything above - don't remember - 15kHz is completely silent with a slight hiss, but that's the general assumption.

The actual sampling rate quality of lossy mp3's mentioned above for example is usually something from 44100Hz to 48000Hz (in 16-bit, which is the limit to most people) while studio devices can use lossless 24-bit 96000Hz up to 192000Hz.

But those are two different things.

It's easy to test your ears using the Audacity proggie, just generate a full spectrum and listen. Choose: Sinus, 1 to 24000, Logarythmic and a few minutes long. It's super cool to see your speaker slowly start vibrating and your ears "noticing" the low bass sound.

Oh, and BTW: OGG gives much better results in 192kb/s then MP3's even in 320kb/s, I converted my whole music collection to that long time ago and wouldn't want to go back.
