Quiet tweeter on Watt 5 unit--access 2 resistors?

I recently acquired a trio of Wilson Audio Watt 5 units.

One of the tweeters is silent. I'm hoping that it's just a resistor that needs to be replaced.

Can someone give me instructions to access so I can see if this is the case?

How difficult is it to replace the tweeter resistor on a Watt 5? I'm fairly handy with a soldering iron.

Thanks in advance.
Changing the tweet is a minor job, but ---- the tweet is a special focal unit. You will have to purchase it from Wilson Audio. You may want to consider a matched pair. Or they may want you to send in you other tweet to match it for you.

I doubt it's the resistors, they're a lot more robust than are the tweets.
