    Hi. I would like to go from active Econowaves to passive, and I want to try the standard HE crossover. Is there a BOM somewhere, maybe with links to the parts at PE?
    Have a look at the first page. Zilch was thoughtful enough to link the project to the first few posts, along with schematics.

      I might very well be blind Pete, but I cant see a BOM for the crossover for woofers with high sencivity (above 95db) there... I dont have any of the woofers in the list either. I use the Eminence Beta 12A.

        I believe that all the tweeters are coupled with L-pads so that they can be adjusted to various woofers.

          has anyone found a cheaper compression driver to replace the D220T? There have been a number of new and smaller drivers out there

            The D220T is pretty inexpensive but there is a new and cheaper version that takes the same diaphragm assembly the D202Ti, personally I would be looking toward the CDX1-1446 for $1 more.

              DIYSoundgroup has a Denovo DNA-150 CD that may work well, but will need a crossover redesign.

                I'll experiment some with new compression drivers, but the Selenium and B&C are working out very well. Anyone still printing PC boards? I can't stop building. lol
