I really think the Iwata 300hz would make a killer system....why do I think that? Because I am working on same. Purple isn't bad, not really my cupa tea given the veneer I prefer, but not at all bad...can always paint (use some acid based wash first). The point is, these are super killer horns (both are). I am keen on getting horn loading lower and direct radiator lower in super hi-end systems
