Det hjelper å vite hva man snakker om, men bevis er noe annet enn løse meninger. Publisering er en måte å få etterprøvd om ens hypoteser har noe for seg...gitt at publikasjonen gjelder hypotesene, vi hadde vel nettopp en ganske vidgjeten norsk forsker som ble avkledd gjennom publisering.
Musikk genererer impulser i luft, disse spilles inn, og overføres gjennom anlegget til lufta i egen stue - og høyttaleren skal generere en impuls som er mest mulig lik orioginalen - og det er den impulsen man hører....så jeg mener at mitt tidligere svar om impulsrespons fortsatt står. Den eneste variable utenom dette og som ikke er beskrevet gjennom impulsen er vel spredningskarakterstikk og rommets innflytelse -og sistnevte er utenfor anleggets transferrespons.
Jeg ser jo problemet med at noe hevdes å virke, uten at noen skjønner og kan forklare hvorfor. Diskusjonen har også gått friskt på andre utenlandske forum.

"Danny"
A customer of mine that I built some rather high end speakers for tried them and loved them. He was freaked out about what a difference they made mounting them to the drivers in his speakers.
After a couple of months of goading (maybe three or four months) I finally tried them myself.
I was skeptical about them and believed and still do that much of the BS on the Bybee site is false and misleading.
However, mounting them to the positive binding post on the back of the speaker (clipped on) did make an obvious difference on my system.
It did lower the noise floor, made the highs clearer and more defined.
It was not huge or dramatic, but was not hard to hear.
I used my wife as a test subject and had her listen. She could tell a difference 100% of the time with them in or out of the circuit, and she is no audiophile.
The guys from Dodd Audio (Gary Dodd and Mark Nash) came over and they also clearly heard a difference and they really liked the effect of them in the circuit.
I could not see a lot of my customers buying these because of the cost of them and the fact that most of our customers purchase very inexpensive kits from us and in some cases the cost of 4 Bybee filters exceeded the cost of some of our kits.
But we also have some really high end customers as well and for them to spend a few hundred dollars to make an improvement in their system (systems well into the five figure range) it's a no brainer. I am more in that camp as well.
So I decided to become a dealer for the Bybee filters. Several other well respected people in this industry have also become dealers.
The discussion then came up on the Mad board and I started sending out pairs of them, free of charge, to be evaluated by the Nay sayers there.
Four of them tried them just as I had initially and they heard no difference.
They did confirm that no inductance, no capacitance, and no real measurable resistance could be found.
The last guy (Dave) heard no difference on his full range Jordans, but then tried them in his pre-amp and said this about them;
"There was no comparison as to the results. The musical product was more transparent with fewer artifacts, especially in the HF. Music flowed with no discernable hash in the treble. There was a definite "Ahhhhhhhh" factor at work. It went away when I removed the BQP from the circuits. Dimension of the soundstage was enhanced as well as apparent size in the soundfield. "
How these things work? I have no idea.
Some, including some that have tried them claim they do not work at all.
I believe there are reasons why they make clear and easy to hear changes on some systems and nothing on others. What they are I have no idea.
