"Bjorn Idland, from Seas R&D, sent along an updated Seas CES 2007 PDF file. The one I posted a couple days ago had a few typos and errors, and notably there was a last minute change and they decided to use ferrofluid in the new Prestige tweeters. (something I'm glad they did) The PDF linked below has been removed, so have a look at this one instead."
