Originally posted by jclyleJust got a used pair of 804S off Audiogon that I picked up from UPS today. The shipping cartons look to be in fine shape. One tweeter has a small dimple in it, and one of the tweeter grills was half way off when I unboxed them The tweeters in both speakers aren't working. I've swapped amps and cables with no change. The midrange and bass drivers are working fine. Has anyone had an experience like this? I am concerned that the cross-over may have been damaged in transit, but hopefully its just a tweeter issue that I can fix myself. I'll be calling B&W USA tomorrow to discuss the issue.
They were insured by UPS.Kal Rubinson

The tweeters are pretty easy to take out so you should do it and just make sure they are hooked up. The silver colored tube at the back of the tweeter just unscrews and the tweeter will come out of the front of the black enclosure. Take them out and make sure everything is connected OK. If it is, then you probably to replace them.
They do ship from Massachusetts by the way.

I believe you can just twist the front-3rd of tweeter 45 degrees counter-clockwise and then they just pull off forwards. This allows you to check the connectors.
Its best to leave the tweeter grills fully on when you do this to prevent further dents.
You're looking at atleast ~$400 to fix them and the crossovers if they're broken.
It seems unlikely that both connectors would come off at the same time though.- Bottom

BTW one simple way to test them once apart is to just contact them to the speaker wires. (This is with music at a "very" very-low volume without any filter.)
If sound comes out then they are fine and you have crossover problems.- Bottom

If the 804S is anything like the N803 I have then DON'T TWIST the "silver colored tube at the back" doing that may damage the wires inside- Bottom
