what do i have?

I have some opder Polk EX 2 way crossovers and some Polk tweeters...I have 2 question if someone would be kind enough to help.

The tweeters have a sticker on the back of them saying db3800...i know about db1000 and 1001 series tweeters but i cant find anything on db3800...I recall reading something quite a while back about them being "Spider Silk "dome tweeters?..What are the tweeters i have?

Im also lookong for information on the EX crossovers...Does anyone know what they are set up to provide frequency wise for each speaker?
