yet another reactive dummy load thread

[Gnobuddy]

That's when you have a pure sine wave but when the amp is clipping it's a square wave so it would be wise to assume at least 50% more than that.

Interestingly, the same peak current delivers twice the square-wave power, compared to sine wave power. That's because the RMS value of a square wave equals the peak value, while for a sine, it's only (1/square_root(2)) of the peak. So you can deliver 100 watts sine, or 200 watts square, with the same amount of peak current!

This also answers the question "What is the largest amount of THD (total harmonic distortion) possible?". The answer is 100%, because when you go from sine to square, all those added harmonics have just doubled the total power delivered to the load. So the ratio of the distorted power (sum of all harmonics) divided by fundamental (the original sine wave) is 100%.

An actual speaker voice coil would have several ohms DCR, typically 3 ohms for a 4 ohm speaker, or 6 ohms for an 8 ohm speaker. As long as we our inductors have no more DCR than that, we're fine. It would be better to have somewhat low DCR in the external inductor, and use a power resistor to act as the DCR, so that the coil has less heat to dissipate.

But my main point was simple - there is no need at all for tree-trunk sized wire in a reactive speaker load, even if it's designed to cope with a powerful guitar amp!

I always like to point out the puny wires in a stock 4x12 Marshall cab. When was the last time you heard anyone have issue with that?

You have not *heard* your guitar speakers if you have not connected them with:



or



I don´t understand the labels explaining them, so they must certainly be very advanced Technology.

maybe even Alien Technology

Hey !!!!! did you ever hear about Roswell?
Did you notice the huge Tecnological advance we have had since?

Do a little Math if you don´t believe me:

1947: Roswell UFO crash .

1952: the transistor was "discovered" ............. yea, sure, "discovered" ......

Those puny wires are special because they were blessed by Jim Marshall himself. That makes them infinitely more conductive than any other wire of the same gauge.

I don't either. But I think "Hyperlitz" would be a good name for a band. Maybe a frenetic high-energy prog-rock band?

Well, I guess since Rush has officially retired from touring, there's room for another frenetic high-energy prog-rock band!

Re: Juan's comment about not really hearing my speakers until...

"Such heroic nonsense..." - Megatron -

I don't know why THAT quote came to mind, but that is SOOOOOOOoooooo stupid. As if that's gonna survive a musician's gear bag any better than all that cheap high-capacitance noisy junk we've been using for decades. You know why <I> use "cheap crap" cables? Because I don't lament the loss of a week's pay when the scrappy thing breaks. Actually, they rarely break after the initial one when the non-Switchcraft plugs crap out...

And I play a Tele through either a Fender or a Dr. Z-sorta-be through efficient speakers. I don't <NEED> any more clear high end extending into the upper harmonics.

Somehow hyperlitz reminds me of someone who drank too much Schlitz malt liquor and is running for the porcelain goddess.

That product can't compete in the market place with my new offering. My product will use advanced raw materials that I discovered after a worldwide search.
The wire is cryogenically treated and then receives a special coating before being formed into a proprietary shape which circulates and dissipates all objectionable gravitational induced currents. The batches are then aged in a dark location for years until the tone characteristics mellow. Only then is the material worthy to be formed into SuperC speaker wire.

Don't forget that it doubles as a Marshmallow/ hot dog roaster which could impart spatial gains.

And, with a few minor alterations of the lead dress, it will also unclog your toilet or drain, possibly for a really hairy or woolly tone.

Lead dress is important, so we do not let other dress interfere. Our wires are made by naked temple virgins.

It's a good thing I wasn't eating cereal or drinking a beer while reading the last several posts. LMAO. Seriously. I usually try to clown in at any opportunity but I can't make this funnier
Thanks guys I needed that.

That explains *EVERYTHING*





By the way, Enzo, how do you like our planet?
