For the 4315, id like to use a smooth cone, in a franken 2108. The 2108 did use a ribbed cone,
The availability of the cone is grey, & I wanted to use the white le8t cone widened for the
7.6cm vc.
Could anyone explain pros and cons of this. Would an aluminum dust help mid range frequency, on the 2108.

For what I've read the ribbed cone providers a clean higher frequency response. So why is it used on a 2235h for instance?

I'like the sound of the 2108 as is, my concoction is a le8t basket with a 7.6cm vc and hopefully a 2108 kit or as I have said a white widened le8t cone.
