Bass shakers only go to 5 hz.

Gene,

WHY!!!!!!!!!!!! That would have been the sweetest thing to read about, from a truthful source. If I was rich I would buy one, I want extention



The phoenix gold one seems more compact, both look very cool, wish i could experience it.

There should have been no sound at all, Just the house vibrating. If you can hear anything at those frequency's it will be harmonic distortion. I played a 20hz tone on the Velo DD15 and I could not hear it at all except that the whole house was about to fall apart, walls, roof and the windows sounded like they were going pop right out I then played a 15hz tone and hell yea, this'll bring your house down

cheers

I have had my hearing verified down to 17hz and up to about 18.5K. It may depend upon the individual.

Yes, this is not only dependent on the individual but also on the SPL at the given Fq. In other-words one may be able to hear an undistorted 20Hz note at 100db but will not hear it at 60db. Below is a 'Threshold Of Hearing' graph from here to illustrate.

Silly, I'd just pull your finger! This thing has "gimmick" written all over it - in case the price didn't give it away.

ya just like those heil air motion transformers {tweeters}of the 70,s

Have you ever heard a Heil AMT???

I was going to say, old hat; helicopters already used this principle in the 40's, but Brian beat me to it.

Seriously, I hope folks are aware that high levels of sound at those frequencies could permanently damage body organs.
