    Of course it depends on the facilities one has, I am good at construction but have not got great facilities. Imporovising is Ok for a small design job but if the volume of work is high it becomes tedious.

    My situation is a same, I don't need many tools, this is my "copy center";
    P.S.
    There is no tedious work in the DIY!

    That is some serious dedication going on there.
    I hope they sound as good as they look.

    Do you assume, that you will get poor results with such speakers?

    I will show you one of my projects, which I had to change basically right at the very beginning - the back speakers , let's go;
    The loudspeakers are "SEAS"- Excel T25CF002 ", W18EX001- 6,5"
    Everything is handmade, no "CNC" machine is used.

    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 speakers. 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 .

    Another position of internal ribbing in the cabinets /p.-1/;
    For the next stage I made this "home matrix", with its help I bent 8 layers with 4 mm beech plywood;

    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/

    I have to make another post, sorry!

    My method of finding an internal volume of a complex construction was discovered long ago,
    the answer was given so many years ago,/about 2500/ of the Archimedes genius!
    The volume per liter of water is equal to the volume of 1 kg. and 1l. Water = 1 kg,
    -their specific resistances are the same, with very little error.
    I will say it in a more understandable way:
    - if we have 20 liters of water in a bucket, this bucket will weigh approximately -20 kg.
    - if we have another liquid in this bucket, we may have 20 liters, but we will not have 20 pounds.
    In my method of measurement, i do not immerse the inner construction in the water, just I measure the weight and deduct it from the total volume.
    There is no simpler and more accurate method for finding the volume of a complex body,
    Archimed's method is flawless!

    Any other material we use to fill, we need to know the "ro" of this material.
    On the second picture,the red line is the waterline, the vas of cabinet must be fill with water next to it / everything must be perfectly horizontally!/.
