As Nikki told me, they dont have any tweeters.
but i have serching for information about those speakers on the internet and have found an comment that they still are available.
But i realy dont know, that colud be the last tweeter i read about.

Hi Alex,

I just bought 780 Argonaut in Grey color; wished it's black like yours. Still waiting, probably next week , then I can compare with
Apogee C Minor.
You mentioned about crossover; have you upgraded the caps to MKP ?
Have you taken pictures of the crossover ?

Been looking low tolerance PP caps ( 5%) to replace the MKS you mentioned.
Check this out:
http://cgi.ebay.com/ws/eBayISAPI.dll...MEWA:IT&ih=012


http://cgi.ebay.com/ws/eBayISAPI.dll...MEWA:IT&ih=002

5 uF ( will be in ± 10% tolerance of 4.7 uF).

Will what do you think ?

Pls advise if you have done the mods; if you did - did it improve the sound ?

Cheers:
ricoh

Anybody able to do a diagram of the speaker cables to the cross-over. I unsoldered mine and gave the the diagram to a colleague who has lost it. Also need to replace the capacitors as mine have melted - seems previous owner must have enjoyed these speakers at full volume :-(

Thanks

Steve
