speaker drivers; where to purchase and which one's?

I own a pair of artemis-eos speakers, which are stand mounted; they are similar to the sonus-faber extremas. The company is no longer in production. I suspect I need new drivers for them, and since I have no experience in this realm, am wondering where to get them, and which are considered "the best". Any help would be appreciated, Thanks,Larry
Not sure what drivers you have but check out zalytron.com they have a large selection of high-end drivers and if they have it you will not find a better price anywhere.
The two choices they gave you are very good but you can also try Partsexpress.com they carry items from companies like Dynaudio, Audax, Morel, and Scan-Speak. From the two choices they gave you, you can get a free catalogue. Also from Parts Express but there internet site is actally better than the catalogue. Good luck on your project and building loudspeakers is much more fun to me than going out and buying them.
