i tested one and it read .9 ohms and figured they are 1ohm. Tested second and the other tested 4ohm . well i atleast got one not blown. I hooked it up to my kac-x650d 300rms sub output and it sounded wonderful for free air. I leared ground zero is famous for making the loudest subs in the smallest enclosures. These subs are very compact stamped basket with single slug magnet. It would.help build an enclosure if i could find the parameters. I figure they are 500rms motors. I got one for the orginality other than and figure ill replace the second with updated coil or whole recone if i can.i see 10 inch subs with same dust cover but 4 spoke basket and cannot find anything .
