subsonic content
acousticians prefer ?infrasonic?

Below 40Hz, bass (from a more limited acoustic, but still infinite electronic repertoire
of instruments) becomes more tactile again, and by 16Hz (or some lower frequency
depending upon physiology), it is no longer audible through the ear, but
solely through bone conduction. This alters the way we hear, since sound is transmitted
much faster through solids (the earth, the floor, the feet, the skeleton) than
through the air. It is therefore possible for sub-bass signals to be ?felt? ahead of the
higher, audible components. This effect may be noticed in thunderstorms.

Ultrasonic content

High frequencies (hf, HF, treble) begin at around 5kHz.
While human conscious hearing stops around 20kHz, higher, ultrasonic frequencies
in music, up to at least 80kHz, can be perceived by the brain.
When frequencies in programme that are above 20kHz are
filtered out, sensitive listeners notice a lack of vitality. More recently, it has been
demonstrated ?objectively?, in the sense that specific neural activity and chemical
production has been measured, that the subliminal perception of the ultrasonic
sounds associated with music enhances pleasure.

Loudspeaker drive-unit basics

There are six main types of speaker drive-units or drivers used for quality audio
reproduction. Another name for a driver is a transducer, a reminder that they transduce
electric energy into acoustic energy, via mechanical energy.

First 3 use a common voice coil.
1.Cone drivers
2.Compression drivers
3.Soft and hard dome drivers
4.The ribbon driver
5.The electrostatic source
6.The piezo driver

Impedances
A speaker?s nominal impedance is commonly (and over-simplistically) described
by a single round figure, usually 15, 8 or 4 ohms for the majority of moving-coil
drive units. With ribbon drive units, or whenever several drive units are paralleled
to increase handling or coverage, lower impedances of 3, 2 or 1 ohms or even less
are the norm. With electrostatic and piezo (hf) drive-unit types, the load impedance
can be higher, but are also more or predominantly capacitative (like a capacitor)
across the audio range. This can be far more taxing to the amplifier.

A low impedance demands more current, and less signal voltage is needed for a
given current.
A high impedance requires more signal voltage, to be driven with a given current.

Hello Starcruiser,
The CTGLabs TPU looks like the S.M. TPU. How do you know it is not functional?

Was his own statement and that of Marco

Please note that I do not mean any disrespect for either or to discredit the TPU but the posted video required clarification. I read and personally believe that CTGLabs was trying to revive the group(s) working on the TPU with a video albeit maybe his actions were misplaced and brought on some undesired repercussions.

I do not want this to disuade anyone from continuing their research in to the TPU, I for one have not stopped but have continued to research and experiement to find the answers since I beleive a device such as this is sorely needed in this day and age (as I beleive CTGLabs and others feels as well).

To find the answers to your questions and more I suggest that you (and others) read the TPU threads in their entirety and you will too find them.

As an additional note I am still interested in what the video claims (it is written in Italian) since i cannot read it. Can anyone translate it for us?

Also, I would like to say that my own experiements into making an operation TPU are still on going (as can be seen by my earlier posts). I will be posting more on those experiements as soon as I get more materials to build my next version.

I have been working on this project for well over a year myself and will continue to work on building my own working TPU. I have read, and will continue to read all posts in this (and other) forums to add to my knowledge, and I suggest all of you do the same. Note that in this world nothing comes easy and answers are found by hard work and looking for those answers. Everyone must contribute so we can make progress.

I also emplore all to share their knowledge and results with others so we can continue to make progress on this as well as other FE devices. Do not look for glory or fame, it will find you when the time comes.

Just my .02

I forgot to mention

My research has brought me to start reading more on the Searle generator now. I gained some interesting info relating to the possible operation of the TPU. It appears that Searle uses Neodynium magnets (the SM TPU does too) to create the electron avalanche required to make power. I ask myself "Is this the secret?" I suggest all read info relating to the Searle Generator, especially the new info now coming out, it may inspire you.

And a many thanks to one of my best teachers, Mr. Hall, for letting me borrow this phenominal device in the early 80s.
We put it on a deaf man who could play piano by touching the sound board. And for the the first time he could hear the fidelity of his own music. And that, my friends, is what experimentation is all about. It's all good.

That means they can put MP3 players on dolphins now. Sheesh. Been done too.

Hello Starcruiser,
If it is not a functional TPU. It must have a battery to power it for a short time. But SM did the same demonistration. I couldn't see any difference between them. If Marco is our buddy, he may tell us how to do it.
