My next project is the development of WiFi electricity ......😎 😎 😎

My cables for loudspeakers are not only made for classic stereo as 12 x 12 mm2 single> single wire, but also as single> bi wire versions of 2 x 12 mm2> 4 x 6mm2 . So I can also go with my cables over long distances up to 20 m, with almost lossless transmission. therefore my cables are also ideal for use with 5.1 > 13.2 surround systems .
Regards MicroMara 😎

That's what I thought you'd said. The coils could be painted or have anything non-magnetic smeared all over them and function the same. You are aware of this?
The coils were matt after 4 years, at least on the surface. However, current only flows on the surfaces of a coil. You would have to measure how and whether the current flow from an untreated to a treated coil changes. However, my focus is now to deal intensively with the new external crossover for the Rf7 MK II. The new, wider and deeper housings are already in the works, I think they will be completed in a good 14 days.

In this example you can see on the lower copper coil in the switch how it looks, at least visually, once before and once after wetting the contact fluid

While the cables look really nice, and I'm sure they also conduct electricity at least as well as needed, I'm still stuck on the use of the contact product on the drivers and crossover. How so and why? And what was the result, specifically?
The "Contact Enhancer" linked by me is used as follows. As a stopper on the bottle there is a small swab in the liquid line at the end of the stopper. All Cichkabel / XLR cables are wetted on the plugs and sockets, both inside and outside. The same is done with his electronics ... on all Chinch / XLR / Digital / KoAx / Terminla pole terminals on the speaker, the contacts of the speaker cables, i.e. bananas, spades, angled banana plugs, etc. Also the cold device sockets to network players, CDP / AMP / Phono / so everywhere. Then reassemble the system 😂
I do not give a sound rating, nor a guarantee that everyone will hear / perceive in his chain ... so I would like to know if someone of you tried it out, what happens there or not .....

I thank you very much for your appreciation for the cables. I get the raw material from one of the leading manufacturers of industrial cables. The specialty of the loudspeaker cables and jumpers is that they all have a copper cable cross section of 12mm2 per phase, including the jumpers. Therefore my MK II is fired with a total of 4 x 12mm2 = 48 mm2. These speaker cables have no inherent sound but only transpose "energy" due to their cross-sections

Phase 2 was room acoustics. What was done there?
In phase 2 of the project, the original insulation material was exchanged for one of the insulation materials currently available, which binds air and structure-borne noise. As a result, the crossover built into the rear of the housing is less of a structure-borne noise than the mid-low woofer. The chassis have more interior volume, the damping factor of the new material has made the inner housing "dust". I would almost like to describe the positive acoustic effects as "dramatic".

@MicroMara your cables look very nice! Where do you source your expandable sleeving?
t is a German company and is called ViaBlue. It is a subsidiary of the "Summer Cables". These are worldwide equipment suppliers for studio and stage technology acoustics

I also develop and manufacture power cables as well as speaker cables and jumpers in / for my friends. My RF 7 MK II is supplied with 12mm2 copper cross-section per phase at the bi-wire terminal ....

Dear Sir, it is a pity that the discussion here is still about the fluid. The modification of the RF 7 MK II consisted of 5 stages, the use of the fluid was, so to speak, only the point on the i. You only need to read the opening post again which expansion level had which weighting. Here is a link to a German HiFi online shop where you can buy it. It happens to be a good friend of mine.
Hope this link is working ......
😎
But don't order them all at once, if you want to try it out for yourself, I don't know the stocks .....
Keep in touch .........

Like fine wine, it takes time.
Abit of intrique whether called

If you mean the fluidum (?) You are right .... The fluidum works only through electricity. And of course .... a good wine always takes time and this thread too .... Thanks and regards

I was under the impression that it's made to be applied to contacts that open and close like a relay. That's why I'm confused. Well......one of the reasons I'm confused.
Hello CECAA850 🙂 what confuses exactly, I try to answer all ambiguities ... but I'm not a physicist. Everything I modify with the RF 7 MK II is based on my personal experience, well over 40 years in private use. I am not (yet) doing this professionally, but would be an option ...

Rather enjoying your thread here.
Welcome some more...
Hello Billybob 🙂 I've only been in the community for a good 30 hours. Actually I thought that my thread would hardly interest a person ..... I think I was probably wrong ... Thanks and regards

I'm a little more confused than that, for additional reasons, I suppose.
Hello Glens, what exactly makes you confused? Thanks and regards

he cleaned all the boards , the copper coils and the contacts of all the resistors and the capacitors with the NASA Contact Enhancer. that stuff is somewhat similar to DEOXIT , if I am not wrong here -
Hello Randyh 🙂 It is not a deoxite ... I do not know the chemical composition of the fluid, but my wife is a qualified chemist by profession and comes from physical chemistry, so the use of chemical fluids to optimize the flow of electrons in copper structures is not a voodoo for her. These fluids are used in many technical areas today ... Thanks and regards

There are a lot of us that started out there. Welcome
Thank you for your attention

The other day I did a sound check with "Berhard Allsison's" "Chills & Thrills" ". My music room has a ceiling height of 5.60 m from the second third of the 35 mm2 room. I use an analog sound level meter. .I reached 105 dB, without room modes and resonances. It was a life concert in my music room. It was an indescribable acute experience.

Finally, I also treated the RF 7 MK II crossover, so the boards copper coils and contacts of all resistors and capacitors, with the NASA Contact Enhancer. The result was impressive as you can see

The Horn Tweeter as well as the Mid/Bass Woofer tuning with physically chemical NASA Contact Enhancers which optimize the current flow and act in the copper structures.
All copper coils were treated with NASA Contact Enhancer.....This application has massively improved the step response and the pulse speed of the chassis.
Now you can perhaps understand why I am so enthusiastic about my RF 7 MK II in the opening post

Nice system and story!! I'm guessing I can't interest you in some used bose cube speakers I have.....?
(given that you don't know me, I'm being sarcastic)
Great speakers!!! (yours)
Thanx a lot 🙂

As I have already noticed, the entire housing construction is made wider and deeper so that the wax coils are not exposed to induction. They are also anchored to the housing base with polyamide threads and screws
Thank you for your attention, I feel very comfortable here despite the fact that I live on the European contingent....🙂

One last piece of information about the Contact Enhancer
Before: Is between the two contact surfaces Dirt and oxide layer embedded, there is only a few direct contact points......
After : The contact agent has removed the dirt and the missing parts with atoms refilled. Over the whole contact area is now a positive connection is established. The improvement in contact quality is considerable.
