These are 10-in single voice coil subwoofer I'm not 100% certain on the RMS Watts or the peak power Watts. Given the age of these I'm guessing 250 to 400 watts RMS.
This is a Soundstream Granite series woofer. They are made in the United States and made in Folsom California.
These are in great condition for it's age. They are fully functional with light cosmetic issues. And the voice coils are in perfect condition. There is no spider sag to these woofers.
These are actually stamped with a number that looks to be the number of speakers that were made in the series.
