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


I have a set of Paradigm Speakers that make up my 7.1 set-up.  I had blown driver in one of the ADP 590s I'm using for a side speaker and replaced a driver in it ($300) 

I hear distortion in the other ADP and I'm pretty sure it's ANOTHER blown driver.  The price of the driver has gone up to $500.....same exact part.

Part ID # 2030800007 

I don't know that it's worth it....

Any thoughts?

Scott, pink or white noise might do the trick but a better test would be a set of frequency sweep tones.  Unhook the speaker that you think is ok and play the set of tones that should be covered by the driver in question (be careful of the volume).  A truly blown driver should be obvious.  I don't have a source for the tones right now as I'm at work but I'm sure others will chime in with a link.  Dick
@shweinhold
where do you live and do you still have 1 properly working driver?
I asked because I was willing to spec out this driver and help you find a suitable replacement
HI TIm,

I have 3 working drivers (each ADP speaker has 2 of these.  They way these are built, I doubt that it would be replaceable with anything else.

I can take a picture when I get home (traveling right now)

I live in the DC area.

No pictures necessary,  I would have taken full measurements of a driver.  With that, we could source a suitable replacement.  guessing on a driver like this just isn't the way to go. 
ok,  I understand wanting to keep the original,  good luck,  Tim
