how about the new seas W15LY001

Top row, middle of the attached image below. Grayish cone. The phase plug is brushed aluminum. This is one of a bunch of 15cm drivers I'm about to test. Results will eventually be published.

LOL i was just about to reference zaph's upcoming minitest (but he beat me to it!).

The nextel coned drivers have been out for a while and i wish at least one or two established loudspeaker designs using the 7 incher were around. Zaph's and this test here: http://www.diymobileaudio.com/forum/showthread.php?t=1025 really make me stand up and take notice (price-performance issues aside). very close to the mag cone excels without the associated hideous resonant peak and resultant reduced usable freq range. maybe with the 5 inch some designs will pop up.
