  • Designing crossovers

    I would like to be able to design and build my own crossovers. What all would I need to have to do this? What is a good basic plan for this. Thanks

      Unless it has been addressed; lot of dead links in that sticky.

      wogg An informative website pertaining to some design software. Adding to that would be Room EQ Wizard and ARTA as free or very low cost measurement software with the addition of a umik, or other usb measurement mic. Unibox and winisd for box volume calculators.

      Forgot the link to wogg's site

        Paul Carmody (look for "undefinition" website) was one of the early proliferators of speaker design by buying nothing, just using JB's "PCD" (or, NOW, one of 4 other workalike softwares that are out there - ALL FREE) along with mfr. plots of drivers' freq. (.FRD) and impedance (.ZMA). Almost all Dayton drivers have a .zip file that contains this data. For other mfrs' (usually PDF) graphs of the data, you can use a tracing program (like Fprawn's "FPTrace") to convert the plot to appropriate F/Z files.

        I THINK there's a tutorial on how to do all this on Paul's site (I think it USED to be in the stickies (liked in the earlier post), but a lot of those links are now dead).

        Have fun.

          I built a well regarded pair of speakers designed by someone else first ( Jon Marsh's ModulaMTM, from htguide forum). Many of these completed designs, have associated build threads where the author describes their process. Look through the gallery here.
          Forums like TechTalk, DiyAudio, Htguide have answers for everything, most of it buried by time in the back pages but available to those who search or browse.
          There is a thread called "Introduction to designing crossovers without measurement" in the multi way section of Loudspeakers on the DiyAudio forum that describes software tools and process. I know there are similar threads here, with a little searching (question has come up before).
          The alternative methods involve measuring drivers and boxes. Both methods can work very well.
          Crossovers are a large subject. They are the brains and heart of a speaker.
          It is worth reading until you understand what you don't know, before jumping in too deep, then take it a step at a time.
          it is very satisfying to design and build a pair of speakers, and have someone(else), say, hey, those sound terrific - but it takes care and time.
          The upside is that diy speakers have a good shot at being competitive with the spendy stuff at the local hifi audio shop - we can build better boxes and crossovers than the manufacturers can afford to build and ship.
