Higgh h SEAS

I may be the only reporter to take pictures of raw loudspeaker drivers at this year's CES. But I've always been fascinated not only by the products we buy, but by the parts that go into them. And SEAS of Norway is one the biggest suppliers of high quality loudspeaker drivers. These new DXT tweeters offer controlled wide dispersion. Note the rings molded into the front plates of both versions. These rings produce diffraction, thereby widening the radiation pattern above 7kHz—the first time to my knowledge that this audiophile boogie-man has been deliberately generated to enhance speaker performance!

If these new aluminum-magnesium dome tweeters run true to form, we can expect to see them in commercial speaker designs in a year or two.
