I have a blown driver and I'm not sure what to do

If run in the same cavity in parallel regarding shared back pressures (the most likely configuration), then one would have to replace with identical pairs, then the other speaker would have to be done the same way.

Obtaining a new or used woofer of OEM nature is the strongly preferable  way to go in this case.

Ie, a single driver replacement of a different woofer type, even one designed to be a perfect replacement... would very likely cause it or the remaining original to pop, when the playback levels get high enough.

The drivers on the side are each one unit (and are both the same)

@timlub - are you close to the DC area?  I'm curious about pursuing your solution.

@djohnson54 - did you think of a good test app?

I set up the new gear and it sounds great, minus the one driver.  It's only noticeable at a couple of frequencies.

Scott, a search for "download test tones" will turn up a bunch of sites.  http://www.testsounds.com/ is just one of many.  I'd start with a tone that is close to the middle of the range handled by the affected driver and see if I got any output.  Dick
