Re: Does it really even have a metal cone?

I'm not so sure that it does have a metal cone. That would be a *huge* shift for Sonus Faber, who have always used polypropylene or paper cones for their woofers. In the main text, Ken Kessler talks about the woofer quite a lot but doesn't mention an aluminum cone. The only place it is mentioned is in Keith Howard's measurements sidebar.

But when you look at the picture of the driver, it looks more like the old poly cone Dynaudio drivers. You know, where the dust cap attaches to the cone there is a series of circumferential slots. So I'm thinking that KH just made a mistake and that it really is just a poly cone.

I could be wrong, though...
