BEST HARMLESS/SIGNATURELESS SPEAKERS CAPACITORS.

Dear friends :  The OP thread answer is:

the best Capacitor or Inductor in a crossover speakers is NO CAPACITOR/INDUCTOR. Please let me explain.

Even that I ask for help on the thread and gave characteristics of the crossover speakers and everything I did not took advises on the overall subject.

Things were and are that I decided to make a change in my external crossover and in specific at the corssover filter for the speaker woofers that crossover around 400hz and what I decided and did it is to take out the all silver ribbon ( 2.5kg. ) inductor along the Kemet capacitors down there.

So now both woofers at each speaker are hard wired directly to the monoblock amps and know what: this non-orthodox change makes an incredible/outstanding quality improvement into the whole room/system performance listening levels.

A major improvement. Yes, I'm way satisfied and I want to share here that before this last speaker changes around two months ago I made another change that when I did it I really did not thinking of any quality improvement in the room/system.

Due that my 20.6 ML amplifiers where builded 30+ years ago and even that in all these years the amps were running just fine I decided ( just for common sense. ) to change the power supply filter capacitors in each amp, these are 4 caps each amp ( 70K uf. ).

The originals were Sprague that today is out of the market, I think Vishay bougth it, and I find out exactly the same ones by Vishay ( these were the higher uf caps ) and the others I have no other choice to use Kemet.

Well, I said that I did not expected for any improvement but wrong I was because those capacitor changes in the amps made it a formidable an unexpected quality overall improvement. 

Yes, I always said that each single day is a learning one and my both changes experiences were and are a important and critical audio learning lessons to me.

And guess what: all thoseype electrolytic capacitors were ( original. ) and are " by-passed " by the industry standar and famous WIMA MKP-10's.

So figure, today top and expen$$ive audio electronics ( CH, Boulder, ML, D'Angostino, SimsAudio, Hegel,etc, etc. ) manufacturers/designers still as 30+ years ago use those great MKP-10 ! ! !   and for signal the FKP-1, god.

Dear friends : Yesterday by advise of J.Sadurni that's a close friend of mine and horn speaker manufacturer i wired again the pure silver ribbon inductor to the speaker woofers and it's the first time that that " less is more " does not works because with the inductor in the crossover the sound of those woofers arrived to better definition, now it's obvious why ADS used the inductor/cap.

I'm thinking seriously to try the same with the tweeter crossover and take out the caps and let the silver inductor only, I know it will be an improvement and yes I know two that I'm changing the second order crossover shape to first order. We will see what happen but with the woofers really function.

In the other side and following with the Levinson 20.6s like a month ago I made other change motivated by the same reaon of the other chages I did it and that's 35 years old amplifiers working hard.

So the amps have  at the electrical power input a board with 4 electrolitic 10K uf caps, this is 40K uf each side. These original caps were made in Germany and out of production but I find out what it need it through athe Germany Vishay manufacturer.

Been the change at the mere electrical input of the amps power supply I really don't have any expectations, I did the change only to preserve in good shape the amps but after a half hour  of play I detected/aware of a true improvement that as improvement always is welcomed.
