Identify this woofer?

Pulled a pair of these from a franken-speaker which was in the end not what it was supposed to be.

10 inch baskets, 8 holes, cloth surrounds. No identifying name on them. Any ideas?

The 137 on the back of the speaker indicates CTS, other than that I'm clueless!

Similar one used in a Heath AS-10 according to this.

Thanks, that helps! Plenty of image hits that have a similar basket and rounded square magnet shape, but nothing exactly similar.

I'm hoping to figure out if I can recoup some of the cost with them, or figure out a project speaker I can build myself.

Best chance of successful DIY is to get some T/S parameters. Maybe someone up there has a driver tester?
