I've been trying to track down the difference, in effective, functional terms (cone mass, complance, voice coil dimensions, etc) between the 127H and 127H1... but haven't seen any hard info that could tell me anything solid, one way or another. Gut-level reaction, from seeing both in person, is that there really isn't any significant difference... but it'd be good to hear from a bona-fide source, what exactly is going on...

Anyone dealt with the two cone kits in question here?

Thanks!

Gordon.
