What speakers use SEAS or SEAS-sourced drivers?

I don't know whether you only want speakers that use SEAS drivers for both the woofer *and* tweeter, but the following speakers use the SEAS Excel soft-dome tweeter:
Harbeth Monitor 30 and 40
ATC models starting with (I think) SCM-20 and up

Both the Harbeth and ATC use their own, proprietary midrange units. FWIW, I have speakers that use both the SEAS Excel tweeter and midrange drivers. I think that the tweeter is amazing-- smooth, refined, and non-fatiguing--but the midrange unit I don't care for much.

One of the reasons that the Harbeth and ATCs intrigue me so much is that they use the excellent SEAS tweeter, but instead of the SEAS midrange they use their own midrange drivers which, from what I've read from many sources, are considered among the best in the industry.

Boulder looks as if they are using a type of SEAS driver. But there are lots more listed on this website:

Their plots always looked difficult to work with unless you are a pro.

Jamo concert/ D series speakers they use the excel

There out of business. But the Hales Trancendance 5 uses the Seas Magnesium midbase driver. Here's a pic of them. http://cgi.audiogon.com/cgi-bin/cl.pl?ddspkrfull&1075005205&demo&3&4&

Also my friend has these speakers called Fischer and Fischer. There high end speakers from Germany. They use the Seas Magnesium midbase along with the Dynaudio Esotar tweeter and Scanspeak woofers on the side. Here's a pic of his speakers. He's in NYC. http://www.fischer-fischer.de/start.html
When your on the site, click on Fischer and Fischer on the right side.
Then on the left side you'll see the model numbers of the speakers. He has the SL 550 speakers. Here's a really good pic of the SL 1000 speakers. When your on the site, there the 9th pic from the top. These speakers look incredible. http://shows.soundstagelive.com/shows/avtour2000/frk_03daily.shtm

The Seas 5" midranges are EXTREMELY smooth for the money, but have a rising response that's difficult to tame, so often have a nasal quality. I worked quite hard trying to eliminate this 600Hz to 1k lift in a 3 way design a few years ago, but never found as much success as with their 6.5" that sacrifice smoothness but sound more neutral and open. SEAS is famous for great value with very high QA. Nonetheless, at a certain point I just prefer the Scanspeak, custon Dynaudio, or of course exotic ART (Skaaning) drivers.
