OT: Crossover dampening options

[LowOhms]

But why was it that length or multiplies of that length. I need a scientific explanation, in all my years I have never heard of such a thing. He must have worked out a reason to have internal driver wires almost 5 feet long. It goes against conventional logic to keep wires only long enough to get the job done and allow for servicing.
Do you coil the excess wire up like an inductor of some sort?
Thanks

Bill,

Please re read my earlier post. See this sentence " All his cables were multiples ( or divisors in crossovers ) of that length. ".

DIVISORS, is the key word, in inches, 28.56, 14.28, 7.14 , and 3.07 inches.

If you read Robert's Biography, and Home page, you can see he was a VERY talented and uniquely-qualified person.

Here is what he told us. The Psych Lab at one of the local Minneapolis Universities were doing tests on Baboons, giving them aural signals, and documenting how they responded. They had a long backlog of data, all of it correlated well. When they went from, say 20K to, as I recall, 60K to give signals, all the well-documented test animals got sick, and there was no rhime or reason to their responses.

Fulton, being very talented, and local, was called in, to see what was happening.

He measured the 60K audio signal at the input and output of the amplifiers, and it was perfectly acceptable. When he measured it at the speaker terminals, it was phase-shifted, and bore little resembleence to the amplifier's output signal.

So, it was Mr. Fulton's job to FIX this, as the testing was stymied.

Robert went into his Lab, and did all sorts of original thinking and exploration into cables. He discovered many things, one of them being the 57 1/8th inch length as being a GREAT "compromise" multiple !!!

In the late 1970s, with his successful introduction of the FMI 80 bookshelf speaker, he eventually marketed "for-audio" speaker wires, and interconnects, using ALL he knew about propagation down a wire, There existed back then, smaller " Fulton Brown " and huge " Fulton Gold " speaker cables - late 70s, early 80s. Surely, there are older readers who recall, and perhaps owned these in-the-day.

The baboons eventually were perfectly responding to the 60K signals, and not getting sick, confused, when Robert finished his work for the University Psych Lab.

That's the best answer I can offer you.

Personally speaking, thirty seven years later, it was Robert W. Fulton's original influences upon me - as a lovely person, and how well he conducted himself in front of me in differing situations, that eventually led me, to accept Jesus Christ. His positive ( Christian-based ) influences took awhile, as I was raised in a Jewish family. Now, as of September 2015, I am, at last, " completed ".

I hope this length-of-wire explanation is helpful to you, or others.
