hey @Ceptorman - It was sold as new speaker. There was no mention of "B" Stock speaker. I will have the rest of system delivered by Tuesday so I will plug it in and will have a listen.
I have already reached out to the seller - I am waiting on their reply. If they take the defected tower back, I will be most happy. Else, I will try to use a soft brush to fix the adhesive issue.
Quite honestly, as long as this is just an aesthetic issue and not a sound quality issue, I am OK with it.
