Paper Based Speaker Cone Question

Paper remains one of the best materials for cones. The light mass contributes to efficiency and fast transients. The material also has inherent damping properties, so no ringing issues. Some of the most expensive drivers in the world are made of various paper compounds.

Yes, the stiffer cone materials tend to suffer from high frequency ring, and this temporal smear can be idealized by the brain as micro detail.

When in fact, it is just noise. It also masks signal, in that smear. false detail, and lost detail, as a pair. There are benefits via better tracing of details below those hf smearing bits, but a loss is a loss.


A paper cone suffers a different type of smear, a lossy wideband smear on the initial transient functions which kills motions toward transient resonant smear (the stiff exotic cone fault), in most cases... which can be combined with some of the problems that the stiffer exotic cone materials have (too stiff an impregnated paper, getting it back to the exotic cone problems). It depends on the cone design and implementation.

Basically, all materials in use have flaws, some more than others. It depends quite a bit on the driver designer and how mentally clear they are in what they re trying to do, and how good their hearing is. Of course, how intelligent they are in applying the given package of skills into driver design, is part of that....

I believe that paper is still the most life-like sounding cone material. No other material I've heard yet comes closer to creating the illusion of a natural tone. The vast majority of speaker cones still use it - from extreme budget to extreme high end. 

Implementation is critical of course, as usual. The only thing that would concern me is the durability of the cone surround. Rubber tends to last a lot longer than foam which tends to disintegrate after a number of years etc.

It's not obvious what material Walsh use 
in their surrounds from their website. Give them a call first if you're unsure.
