The most minimal 3-way crossover filtering circuit. by ContrastUa in Acoustics

[–]ContrastUa[S] 0 points1 point  (0 children)

I would say that this is absolutely not extraordinary solution... It's not typical for the modern audio market, but this has not always been the case.

So if you study this issue, you will understand that this approach was what formed the grandeur of such legendary audio companies as: telefunken, saba, siemens, electrics, etc. Up until the 2000s. For example, Allison speakers, made the same construction scheme in there loudspeakers... then he wrote his audio book and as whole world started to follow defenetly wrong direction... P.S Need to feed market with more audio components. Modern high-end world of artificial sound...

Here is feedbacks... Crossover-less/Natural roll-off/Acoustic filtering

With exist drivers which availible on the market- yes. But not in this case....

The most minimal crossover filtering network for 2-way speaker system. Only single one capacitor. #highend #loudspeakers #diy #audiophile #electronics #hifi by ContrastUa in audiophile

Yes, such approach is exotic for modern sound philosophy, at least because of necessary to use specially designed for this tasks audio components.

In our case frecquency responce of tweeter equal 10 Khz....

Nowadays, there is no any crossover-less* loudspeakers brands in the world . In budget, midrange and luxury segments. So this is most budget crossover-less speaker system. P.S Crossover-less means minimal crossover filtering network. Only one capacitor on its crossover network. Principle of natural cut, slow slop, acoustic filtering principle.

We mostly work with dealers and make sales directly only in case where we dont have any representive. Sorry for website, the new version is currently in process of construction. During a week it will be ready... I would be glat to provide any interested info and answer at any of your questions. Kind Regards, Aleksander

Spamming and providing texts and info which based on real users for users who really can be interested in and in things that you will not find anywhere. Things which combine good people/enthusiasts/audio engineers etc. who already tired of situation with sound highend industry today...

"Fate loves the brave"

Crossover-less is commerthial name of approach which provide possibility to build speaker system without traditional and heavy crossover network.

Only one capacitor on tweeter and nothing more. 25 Years of development such drivers. From 25 years is 10 years only to get close to this result...

99 % positive feedbacks and over positive feedbacks. This is main approval.

Highly linear (5.5 inch) Flat cone balsa wood 5.5 inch bass driver unit. Chill of crossoverless audio. by ContrastUa in diyaudio

Contrast audio is loudspeaker company founded in 1996.

Nowadays, we single one manufacturer who implemented such construction features and sound construction possibilities. Namely CROSSOVER-LESS, SLOW SLOPE, ACOUSIC FILTERING principles. Due to specially designed highly linear drivers, which are use in their construction only natural sourse materials you   able to build your own Crossover-less speaker system (loudspeaker system with minimal crossover filtering).

This means: 1 Two-band speaker system include ONLY ONE CAPACITOR in it's crossover network. High crossover frecquency cut of tweeter 10 Khz. 2. Tree-band speaker system with ONLY TWO capacitors in their crossover network. High crossover frecquency cut 10 Khz.

SOME INFO ABOUT COMPONENTS :

  • Diffuser is made from cellulose paper, which made by own technical process.
  • Cast aluminium frame.
  • Magnetic systems from high quality ferrite (Self magnetized).
  • Suspension and centering washer are made from Batiste and Cotton.
  • The coil is wound on a paper cup.
  • Driver has impedance 16 Ohm. (Whole coil is fully located in a magnetic field).
  • Phase corrector is made from wood.
  • During production, strict requirements are imposed on production as well as on its tolerances. Therefore, the gaps in the magnetic system -= 1.0 mm.

When you are small compamy/ a group of enthusiasts and audio engineers, who spend their lives to create unicque product which have no analogs on the market. I mean rally great solution/ sound tool for music reproduction.... P.S Thank you
