Price is certainly right, 6 or more is only $7.24. The pic at the site is not very good, looks like some kind of odd magnet cover. Xmax is only .138 inch, which is NOT enough. Looks like a stamped frame, hard to tell for sure. 200 watts? HArd to tell without much voice coil info.

Nice line array of 10 a side would be around $150

Heh. Thought that might be so. Thankfully there are a lot of smarter people than I here.

Looks like a nice big butyl surround for such a wimply xmax. At the price, I wonder how a guitar sounds thru 8 in a sealed box?

Would probably depend on the skill of the guitar player: very poorly if me, very nice if Mark Knopfler.
