I have 3 of these NICE Vifa 4" coax drivers. these do not have any sort of a crossover on them, you will need to make your own. somewhere i might still have a crossover schematic for them, not sure. otherwise would make nice drivers for an active DSP Bi-amp system.
I have three of them never used. 8ohm. rubber surrounds. sometype of polymer/plastic cone. cloth/silk softdome tweeter.
$25 for all 3 plus shipping
