Can anyone ID the JBL sub in this picture?

Judging from the appearance it looks like it may have been sold along with the L series in the 90's. (L1-L7) But I can't find any record of a sub that matches! And no sub is listed as part of that series. Weird.

This is the only picture I have for now.

Ahh, nevermind - I found it. It's just a PS100 or PS120. Was hoping it was something a little more special.
