May have bad driver on CS350

I picked this up used at a decent price, just started listening to it and the far right driver seems to have a slight scratching sound but only if I lightly push on the rubber surround at the 9 O'clock position. I heard it slightly when I first turned it on so I started investigating.
Sounds great, just an occasional scratch but not very audible unless you are right up on it. If I push on the rubber in the other 90 deg positions it's fine, only at 9 O'clock.
These MW4850's apparently are the same in the CS-250/150 as well? Also the LS/Fx surround? Just curious as if it is a bad driver maybe I can find another speaker somewhere for extra drivers.
This speaker does compliment the 2B's fairly well...I'm impressed... even on the stock caps.

Spin the driver so that the bad spot is on top. This doesn't always work, but gravity does have its affect on driver gaps. My guess is that it won't do much for such a small driver, but its worth the effort.HT Optoma HD25 LV on 80" DIY Screen, Anthem MRX 300 Receiver, Pioneer Elite BDP 51FD Polk CS350LS, Polk SDA1C, Polk FX300, Polk RT55, Dual EBS Adire Shiva 320watt tuned to 17hz, ICs-DIY Twisted Prs, Speaker-Raymond Cable
