Well, if I may, did you ever heard of Fertin Full Range drivers ?
There is a thread on them.

The last serie is surroundless with a clever system of carbon rods to center the diaphragm.

Comparing these drivers to conventional suspension speakers reveals how that surround affects the sound. It is a very intresting experience.

To day the best full range Fertin seems to be the 20EX M7 driver.
One should give them a listening.

They were on the Da Vinci stand at the CES of Las VegaS.

Hello Cherel!

Yes I have heard of but, never actually heard Fertin Full Range drivers. I find their surroundless drivers to be quite interesting in concept and really wished I had a chance to hear them.

I'm sure you're correct that comparing these drivers to conventional suspension speakers would reveal how the surround affects the sound. I'm curious if the Fertins are possibly capable of going out of alignment and how difficult it would be to realign them if they did.

I did not mean to imply the Beta's have problems. I said they represent a problem, well actually quite a few.

How does that sound come out of those speakers?

How does a speakers sold to kit builders in the 70's, pound speakers that cost thousands today?

When something sounds bad through them, its because its bad.

Those kind of problems.

I have a friend that owns a pair and his friends won't buy a piece of gear before they hear them through the Corals.

spresto9. Those look great. I built the 208Sigma BLH cabs for my 206E's. Had them for about 2 years now and love them. I am in the mood to make another set of cabs.

What's the bass response like and how low do you reckon they go?

Scottmoose/Planet10. I have some Lowther PM6C's which I picked up at a bargain price. I have tried these in the 206Sigma cabs and IMO they don't really work. Not enough bass.

I really like the look of spresto9's changs. Would these work with the Lowthers? If not which cab is likely to give the best performance?

To an extent. They'd need to be fairly heavily modified for an appropriate alignment, which would depend on how your particular units spec. Lowthers are inherently rather characterful of course, which needs to be kept in mind.

Now those are really funky.

They are sorta like upside down Metronomes... did you model the quadratic taper?
