    Algseade Joror's DIY Audio projects

    Hello,
    My name is Georgi, I live in Sofia-Bulgaria, 58 years old,I have a happy family in 37 years and i am grandfather.
    I have been duer of the time, when I remember myself- such was the socialist system.
    A few days ago I made a registration in this forum and wrote a letter to the moderator, to tell me, which language to communicate with you - I have no answer and I decided to write in English/ I can also in Russian/, but I'm not sure,are this language is used in this forum .
    A model of my DIY loudspeakers i have served Ti6k- JBL. My first contact with
    them, was in distant 2005.
    I started working with them in 2009 and finished in 2012.
    The loudspeakers are "SEAS"- Excel / Tw-1”, Mw-5”for center 2? 5.5”,Bass-8,5”/ and cross-over parts- "Intertechnik".

    Nominal impedance- 8 OhFreguency Range 30Hz-20kHzCharacterstic Sensitivity(2,83V/1m)- 87db
    Long Term-110W.
    Have are some pictures, if there is interest, i will continue.
    Regards!
    Joro

    In fact, this is a very old project and I do not have detailed materials for the filter measurements. They took place in a DIY Laboratory "Pas Bg" in 2009 yer and this firm not exist from а long time.
    I've registered in more than 30 "DIY- Audio" forums and the history of these columns, is popular in this "duer" circles.
    And another explanation, why i do this post on this site? I wanted to buy an integrated amplifier from Estonia and there I accidentally came to you.


    Naturally, I will tell you about the history of these speakers, but before that I will present you another project that is up to date.
    Thank you for your attention!

    I will show you one of my projects, which I had to change basically right at the very beginning - the back loudspeakers ;
    The speakers are "SEAS"- Excel T25CF002 ", W18EX001- 6,5"




    First I paint the model as I like it / I do not like the standard prisms / I don't use 3D programs. I'm an electrical engineer and
    all I need is an idea, a pencil, mathematics, elementary geometry , a perspective view and that's it ...
    We all know, what is the ideal shape for the loudspeakers. For technological reasons, it is difficult to do, especially with three tape loudspeakers. I strive to make the second most effective form - the egg.
    To begin with, I schematically design this way;
    I calculate the approximate volume, how do I find the right volume, will show you later in my project ;
    P.S.
    In order to save your time, I will allow myself a clarification:
    -Everything in this project- idea, design the filters and the overall workmanship of the cabinets to the last detail was done by my hands. I not used "CNC" machine .

    I am approaching to the measurement of the internal volume:
    From waste material I made this gadget ,that takes part in the measurements and when assembling the cabinet:/p- 4; 5/:
