Need info on these JBL Drivers

One of my coworkers brought in some drivers from what he said were some old JBL cabinets that somebody had tossed out.

10" woofers and about 4" mids. He did not have the tweeters.

Numbers on the magnets are 65434 on the woofer and 65437 on the midrange.

Average looking woofer with a tan colored ridged paper cone, foam surround and about a 30oz magnet. Midrange has a black paper cone and about same size magnet.

Do these numbers seem familiar to anyone? I'd like to build boxes for them but I need to know at least some of the specs.
