Ohayo, What Subwoofer In Your Country U Use?
-----------------------------------
Sup 
Did you know that... 
[u]Subwoofer[/u] refers to either a woofer, or a complete loudspeaker [u]dedicated[/u] to the reproduction of 
bass audio frequencies, typically from [u]150 Hz down[/u] to 20 Hz.

In the case of a rotary woofer, it is 
possible to reproduce frequencies down to 1 Hz.

This spammer passed the checks  :bad-words: ... However the way he posted the link is invalid. Note that posting link here is nearly useless because links posted into the site are visible only to registered users , not even the search boats can see them, so they are directed only to people of the site.  :mmmh: Maybe Andreas is interested in this subwoofer something (however I can make a burp lower than 1 hz  :D )

P.S. Note that u'll get an "user doesn't exist if you reply to this message"

It seems to me the person is passing a bit of information. 

A Sub Woofer is a large speaker that can produce a bass note down to 20 hertz. 
He is stating that a rotary speaker can play or go lower to make a sound although you can only feel it rather 
hearing it below 20 hertz.

In most speaker cabinets that play music they have three speakers. A tweeter, midrange and woofer. They where known as a three way system to produce sound threw the audio spectrum. Then cam a Driver or speaker as you will known as a Sub Woofer to produce lower bass tones or notes.  :D
