How much does one of them things cost?

 
 Hopefully the price will be really LOW.

One thing that bothers me with the fan concept is how quit is this thing in very quiet passages in the music. It may be audible which would ruin it for me.

Speakers can do amazing things. I once referred to a hi fi listening session I was invited to many years ago. The entire room was shaped like a large exponential horn and you sat toward the wide end of the room. An 18" woofer was set inside a concrete enclosure that was buried 6 foot under the ground and fed the mouth of the horn. This guy was into organ music and he was aiming to reproduce 16Hz at the same level as other frequencies. It did believe me. It was the most breathtaking thing I have ever heard too so I know how Mike feels hearing something so incredible.

It is also important what is handling the higher end too. This guy had electrostatic speakers driven from class A Williamson valve amps so no more needs to be said there. The top end was also breathtaking.

What I liked about his setup was that any material that contained very low frequencies certainly gave it out but normal material that may have not gone so far down sounded very normal as well. I remember playing a modern pop record at the time too to test it out and it did sound stellar. It is easy to have too much energy down there and it can get distracting. How well balanced it is into the rest of the system is so important.

But I go give credit to Mike for pointing out such an unusual way to get those very lower octaves being heard or felt.

"You shake my nerves and you rattle my brain!!!"
 
This is real rock and roll, I want one of these.
 
I need it to complete my Symphony in Am for Foghorns.  The overture is just not working right now.  I'm sure this will fix it.
 
Then it's just a case of waiting for the correct air temperature, dew point and sea conditions and I'm going to be golden.
 
Thank goodness, I never thought I'd see the day that I could finish this piece but this changes everything.
 
I'll whack it up on SoundCloud when I'm done.

It's hard to call it infra sonics.

I just got back. We listened to a 4.09Hz test tone. I heard it and felt it. It's hard to call it infrasonic after you have heard it.

The house resonated at 8hz and the root tone was masked by the sound of shaking stuff.

At 4 hertz the house settled down and it was clear and well defined.

Does this thing add anything 'extra' to the signal?

I didn't think the anatomy of the human ear was capable of registering anything with a lower frequency than around 15Hz.
 
I would have thought that only animals such as elephants, due to the actual physical dimensions of the structure of their ears (i.e. large and voluminous), are capable of 'hearing' (as opposed to 'feeling') sound at 4Hz.
 
Mike, have you got enormous ears?
 
Or I'm wondering if matey boy is somehow pulling a fast one?
 
Or maybe it's an "Emperor's new clothes" thing? I mean, if I'd shelled out $20,000 on a sub that can deliver audio at 4Hz, I'm definitely going to hear it.
  
  
  
 

 
I just found these:
 
 

 

 

errr, can you repeat that, Strummy???

Sorry George....
 
 
But I can't.

well I didnt catch everything you said, bit of an auditory problem here, old bean..

If I only had a purpose...or wuz won...
