Hi All

Is anyone able to explain the differences in the 421 and sister models. Is there a website that does this rather than having to go through it here.

I know the 421A and 421-8H's are 15" and 16" frames respectivly, but are there differences in the 8H versions, or any other major differences between them. Where do drivers such as the varients of the 418 and 420 fit in to this?

Thanks

Nat
