SEAS Full Range Single Driver

vizion · 4th November 2007, 08:11 PM

There's a new full range, single driver in town, the SEAS Exotic F8. It will be unveiled at the Venetian hotel for the Las Vegas CES 2008 show. Knowing Seas, the driver will pack some great low end bass. I wonder what magnets they use.

OLD NEWS, please delete.

I agree that this is old news, but maybe for a different reason. The whizzer cone is shown very clearly in the thumbnail. While whizzer cones may have been an acceptable solution for the lack of high frequency performance in the 1930s when there were no true tweeters, haven't we moved beyond them?

Whizzer cones reproduce nothing. They are only a source of spurious high frequency resonances.

There are limits to full range. If you must resort to a whizzer cone then you have gone beyond those limits.

Whizzers can be tamed. Put some foam or some other lightweight material between the back of the Whizzer and the area of the main cone behind it and it fixes alot of the whizzer issues.

SEAS are relatively cheap compared to the quality, but lately they have not had many drivers with high sensitivity. Hopefully we'll have a good alternative to the made in china Fostex.

I have a pair of these Seas full range drivers:

Just wondering if anyone had any info on them, because I can't find anything. What sort of cabinet design would work best?

I feel that whizzers are kinda fun. quirky.

can be highly refined. i feel that the one in the fe166es-r and 206es-r are state of the art. despite beaminess typical of any full ranger, there is simply no whizzer weirdness in these drivers.

no foam, damping, etc either..

My pair, designated X1's, just arrived. They have what look to
be the longest excursion yet in a full range driver. Here's
a couple pictures

Nelson Pass · 15th November 2007, 06:18 PM

Here's the back side, showing the Alnico magnet.

Impedance is 4 ohms, resonance is about 40 Hz, and sensitivity
around 93 dB or so.

I'll be loading them up this weekend and getting some initial
measurements and impressions...

Are X1's from Seas or Pass Labs ?

how do mere mortals get a hold of these and are complete specifications available?
