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

I heard something wrong in my left Vandersteen 5A...  I  ran the Ayre break in disc which has a slow glide tone from 20 - 20,000 hz, which revealed that the midrange was the culprit.  I took out 4 screws, cut the wires to the driver and sent it back to Vandersteen who rebuilt the speaker for 150.00.  It now plays as when I first bought the speaker.

I ordered my PA7 and AV60 today, as well as a power conditioner.

Anyone have a recommended app or sound source for testing the speaker with pink or white noise?

I want to make sure it's blown before I get the new driver.  It may have just been (I'm hoping) a distortion from the amp at that frequency (wishful thinking, I know)

Thanks for all the advice,

Scott

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
