Default Supravox 215-Exec or Fertin 20EX?

Any comments from Fertin and Supravox field coil owners on:

- Have you compared Fertin versus Supravox?
- What did you decide?
- Box design used?
- Favorite Amp?
- Purchase Source for drivers?
- Issues?
- Used full range or with sub/tweeter?
- What did you own before?
- What do you like about the sound?
- What do you dislike about the sound?
- Pics?
- Measurements?

I live in Southern California and fortunately, there is a Supravox dealer close by. I've heard that Fertin makes a formidable if not equal/superior driver as well. Thanks for any comments.

I just received a pair of Fertins 20EX shipped from France. I have not set them up or had the chance to listen to them. I too considered the Supravoxes, but in the end, I went with the Fertins for several reasons. As best i can tell, the Fertins are more techincally advanced. The Fertins have the following

- cryo treated silver voice coil
- carbon fiber spider
- wider frequency range. I am told it goes from 40Hz to 20Khz. No tweeter is necessary.
- Better quality. The Supravoxes had issues with the motor falling off during shipping. This has been corrected I am told.

There is very little info out there on both these drivers. The Fertin rep in Canada says his drivers are better, whereas the Supravox rep said his are better.

I did contact one individual who has listened to both. He liked the Fertins better. And from what I could gather from the various posts I came across, the Fertins seem to be a little better.

Cost wise, the Fertins are cheaper (sort of). After shipping and customs, the Fertins and the Supravoxes are about the same, give or take $100 or so.

One last comment, the build qualiy on the Fertins is amazing.

Hope this helps...
