Paralleling loudspeakers without consequence
« on: June 14, 2018, 08:34:00 am »
Apparently this product allows you to connect multiple loudspeakers in parallel to an amplifier without presenting a very low impedance.
All without any configuration or setting-up or extra power - it's entirely passive.  8)

Thru non-exhausive searches I have come to believe that it used to be known as BCS Multi Speaker System http://www.cggeorgallis.com/readNews.php?nid=119
The patent is here https://patents.google.com/patent/EP2688313A1
Amusingly, all the test results in the patent convince the inventor that it works. You may disagree. I disagree.
They were at Infocomm this year (last week). They got a prize last year :palm:

The data sheet says that it "eliminates the need for 70V - 100V transformer products," and the only way I can see this working is if the box contains those transformers.

The claims for that gadget put it well beyond any commonly-known technology.
If what they claim is true, then they have found a way to soundly defeat Ohm's Law.
Free energy from the "zero point" (surely not far away from their "zero ohm") should be here soon. 

 :palm:   :bullshit:

Even if the patent illustrations weren't over-compressed to lose many horizontal lines, the diagrams are pure gibberish. The fact that this patent was granted confirms that there are no technically-knowledgeable inspectors remaining in the USPTO.  But we knew that already.

Glancing at the product for five seconds make me think it has a transformer transforming the input down to be able to drive low ohm loads.
To bad a speaker ain't a resistor and multiple speakers often means some distance between em what means fairly long cable runs, bad combo for low ohms load.  :palm:
No point in making a point just to make a point, that would be pointless.

Hold on, it does do:

Uniform power distribution over long distance cable runs

In that case:  :palm: :palm:

I tried reading the description from the patent - but by the time I got half way my brain was threatening to throttle me.

There are several mentions of capacitors and "high pass" - and I was beginning to wonder if I was looking at a crossover network.  The unreadable diagrams did not help.

There is also a claim of "no power loss" which I find fascinating.

The second diagram is mostly discernable if you fullscreen it.

It's not even a proper crossover network, it's just two parallel RC filters separated by some large caps. :-DD

There's a resistor and capacitor to ground, then through two bulk storage caps (in series parallel), then another resistor and capacitor to ground. :palm:
