I acquired these two crossovers N809.8A along with two bass speakers units 418 -8H series ll (Musical Instruments) plus two compression drivers models 808-8A 8ohms . and 807 -8A, (with the metal horns ) i got all of these components in a box from an old theatre in Copenhagen , my question is if could built them as speakers to be use with my stereo system ? i would need the schematics how to connect the bass speakers along with the compression drivers ,(by the way does anyone know if these drivers can be use as tweeters ?) any helpful thoughts will be greatly appreciated ! cheers
