SL3 woofer replacement advice

One of my SL3 woofer started to make loud popping sounds all of a sudden last night when playing bass notes. I checked it out and it seems like the cone isn't moving at all when playing music while the other one is... Cone looks like it is in good shape. Not sure how this happened but the other day i was unplugging something and forgot to turn power off and had a very loud pop go through the system.

I assume I need to just replace the speaker driver, correct? I am not about to spend $500 for a pair of woofers for these old speakers so what cheaper alternative is everyone using? I have these crossed over at 80 hz with below going to 3 JL audio Fathom 113's

thanks

Get a pair of the aluminum cone Scanspeak Discovery 26W/4534G ($94 each). This has become ML's officially endorsed 10 inch, 4 Ohm woofer replacement, as ML is sold out of the $500/pair Vifa aluminum cone woofers.
