Drivers for Paragon Acounstic JEM

Are these woofers still available?

I've had the Paragons for 14 years and never dreamed of replacing them, but the woofers' surrounds are torn.

And Yes, they are 24W 100 with 3 ohm resistor in series.

I should add that the drivers themselves are 8 ohm, and 4 ohm version (new, with rubber surround) are available. The speaker designer must have added resistors to bring the impedence up or reduce woofer excursion. Maybe I should just buy the refoam kit and then experiment with removing the resistor?
