Building a set of speakers from a collection of drivers one happens to have around, and without considerable knowledge, is not likely to have a good result I am sorry to say. My usual advice to the firsttime speaker builder is to do what I did, and to build your speakers from plans that were designed by a true expert. This includes using drivers (the raw speakers) that the designer recommends, not whatever you have handy.
However, if you are determined to proceed, you should do some research and learn about some basic concepts such as:
- Thiele-Small parameters: how to determine them for your drivers and how to use them to design your cabinets
- How to determine a good crossover frequency and slope
- The advantages and disadvantages of various crossover types
- Basic electronics. You should own and know how to use a volt-ohm meter, at least. It is also known as a "multimeter" or DMM (digital multimeter) In addition, an LC meter for measuring inductance (L) and capacitance (C) is very useful for testing crossover components.
With a bit of luck and the above knowledge, you will have speakers that do not sound too bad. With a bit more luck, they might sound O.K. The Websites and books that have already been suggested are good places to begin learning. Since they are in English, and English is not your main language, perhaps similar places for information exist in your language?
These are the simplest basics. True speaker design, whether by professionals or serious hobbyists, involves considerable knowledge in fields such as mathematics, filter theory, electronics, and acoustics, among others. That is why I did not design my own home-built speakers and probably never will design future ones.
This may seem discouraging. Alas, it is the simple truth.
