This is Beyong-Human!

 

Top-Gun, time to get to work too.

 

Well, let me drop some qoute from a source :

 

The average speaker that people listen to, does not reproduce the frequency range from 40 Hz to 80Hz. This is true even for many expensive "powered" speakers. You really can't hear this range of frequencies unless you have awfully big speakers or a sub-woofer on your system. But the difficulties don't end there.

 

Because speakers don't reproduce this range, speaker manufacturers often "enhance" the low-end by boosting the sound output for the next octave (80 Hz to 160 Hz). This makes the speaker sound like it has more bass response but they are actually substituting extra energy in this octave for a lack in the lower octave (40 Hz to 80 Hz). This makes it hard to judge the sound, add equalization, etc.

 

When subwoofers are added to speakers, there is still the boost in the higher bass octave and additionally there can be a "hump" around the point where the subwoofer and the speakers are both reproducing sound (around 100 Hz). The "truest" speakers are those huge studio monitors that no one can afford except large studios.

 

 

How Audio Engineers obtain the '40 Hz and below'-feel :

 

We often filter out the very lowest frequencies as a first step in mastering. We often will use a 32 Hz high-pass filter, which has the frequency response. Even though there are no fundamental frequencies below 40 Hz, there can be energy in this range caused by "rumble." In addition, however, the filter slightly reduces energy up to 64 Hz.

 

This reduction of the low bass energy has practically no effect on the bass sound except to make it a bit clearer and make the overall signal a little louder (after adjusting the level back to normal after filtering).

 

 

Another fact of recording :

 

Equalization charts often identify frequencies that you may want to boost on the bass guitar as being 400 Hz, 800 Hz or 1.6 kHz. boosting one of these frequencies will often make the bass line more distinct and clear.

 

An equalizer does not generate harmonic frequencies, but simply makes them louder or softer.

Think again.

 

ps : Stereo Electronics, you might find this very familiar. haha.

Oops.... i'm wrong... haha... anyway, im716 does have tight and fast bass. bass extension reach to the 40Hz region as far as my ear can hear...

 

I'm impressed the fact you can hear 40Hz from I wonder what instrument that would be. Are you familar with the various instruments that can go below 60Hz?

 

Lowest range of some instruments for your reference.

 

1. Pipe organ - 20Hz

2. Double bass - 40Hz

3. Tuba - 45Hz

4. Basson - 55Hz

5. Double basson - 25Hz

6. Piano - 28Hz (If you can tell the difference between acoustic and digital piano first)
