1. step 1

     -Read our tutorial articles to get a detailed picture of what hifi


     speaker design is all about.

     -Browse the list of loudspeaker manufacturer websites and use


     our database of downloadable loudspeaker datasheets to select


     your drivers.

     -Choose the right design software that suits you best to


     calculate your enclosure dimensions and buy everything


     you need from a retail shop.

  2. step 2 v2

      -Assemble your crossover-less speaker and let your lab equipment


     (or measurement software) acquire the necessary response


      measurements. Use your crossover design software to decide a


      crossover network that fits your acoustical targets.

     -Browse the list of component manufacturer websites and buy all the


      necessary components.

     -Use a suitable pcb and your soldering equipment to conclude


      your crossover network implementation.



  3. step 3



     -If you get addicted to hifi speaker design you can try to


      broaden your technical background by consulting our


     book review section and -why not- browsing the


     journals of the existing audio societies.

     -You can also get closer to audio enthusiasts' community


     through our list of worldwide audio websites,


     web-magazines and discussion fora.
