Anyone used Peerless SC165 in their project?

Hi. I'm kind of new in speakerdesign, but have built many things of wood during the years, so the . Just upgraded the drivers in my Carlsson OA-50 speakers, and was thinking of maybe building a new pair of speakers with the old drivers; two Peerless SC165. I couldn't find any designs with Google for a couple of speakers with these drivers, and neither any datasheets with details about them. Have any of you used these drivers in your speakers? And do someone have a copy of the datasheet I could have? Many thanks.
