  1. Hello Alexander!
    I just ordered the construction kit, but I am considering whether you could not build the Cinetor evo fully active with a fusion module (in the sense of a studio monitor or mini PA).
    Have you ever thought in this direction or maybe even already done something?

  2. Hi all,

    I have purchased the Cinetor Evo blueprint. I would like to build the speaker first, because I run a very high quality DIY subwoofer for each channel, which can also play easily up to 200Hz or higher. Do I have to pay attention to something or does the tonality change unintentionally?

    Best regards, Dominik

      1. Thanks for the feedback. I have now carried out the separation at 100Hz, fits very well.
        I have one more question. I still have a good amount of alubutyl lying around here. Would it make sense to use this to calm the inner walls even more?

  3. Hi Alexander,
    I'm thinking of building the Cinetor-Evo as 5.0 system. Can the Cinetor-Evo also be used horizontally for the center? For all boxes I would have to resort to a very close-to-the-wall setup (also on the side). I suspect that the HWG variant would be advisable here? The turnout is not ready to be purchased, but should always be built specifically, right?
    Thanks and Regards

      1. Hi Alexander,
        Thank you for your quick response. Is there an alternative construction proposal for a center box that can be placed and harmonizes with the sound of the Cinetor? Standing works unfortunately not in terms of space.

  4. Hi Alexander,
    I find the Cinetor-Evo very interesting, but I would like to place the speakers at about 20cm distance to the wall on stands.
    Do you see a problem with that?
    Best regards,

      1. Thank you for the info. What should be a sufficient distance to the side (wall) in your experience?

        Best regards,

        1. Cinetor-Evo is less susceptible to lateral reflections than other loudspeakers due to the directionality (WG). Nevertheless, I did not want to go under 50cm. More is usually better. If the walls are very close you can experiment with sound absorbing materials.

  5. Hello, very nice speaker!
    I'm actually making a similar design:
    same drivers with wg, slighly larger box, sealed!
    ... because there'll be a bass section:
    same enclosure, with dayton RSS210HF sealed.
    Mu question: why your xover point so low?
    I think LR2 at 2kHz, with hypex fusion.
    great job!

        1. Hi Enrico!
          No, because in terms of

          "Directivity (horizontal and vertical), distortions and power handling"

          LR4 gave the best results. I do not believe in audible phase shift due to LR4 filters. The other side filters may result in more audibly problems caused by operating drivers at their limits.
          Best regards

          1. thanks Alexander!
            WG148 and WG300 with this tweeter before choosing the big one?
            Thank you very much for all this information!
            Best regards

  6. A very interesting speaker for my next project.
    What is the situation near the wall? Will there be a HWG version like the "old" version?
