This is a vintage Bozak B-199A woofer with the B-207 tweeter assembly ring/frame. No tweeters are included. I attempted to remove the ring but did felt like the sealing gasket would separate from the woofer, so I left it alone.

 To be a B-207A assembly, just add tweeters & the crossover.

Woofer has been tested with a 30Hz test tone & works fine. Sold as is with no returns.

Impedance is 8 ohms & DCR = 5.6.
