I'd like to see an intelligent discussion regarding Polk's older coated paper cones and their newer blue cones (used in the i-series speakers). To keep comparisons on the same level - lets limit the discussion to the 6-1/2"ers.
What are the differences? Which is better? Why the change?
The old coated paper ones seemed to be pretty good and reasonably durable. Both use rubber surrounds.
THe newer ones are - well - different.
Personally, I prefer the old glossy-looking black paper cones.
I may be wrong.... but, I think the older ones just simply sounded sweeeter - imo.
I suspect the newer cones are easier to mass-produce.
Is that the reason for the change?
Likewise, is there any significant difference between the old SL3000 tri-laminate tweeter and the new tweets used in the i-series speakers (RT55i)? Its my understanding that both are tri-laminate.... but, they look/appear different. Again, which is better? Why?
Thanks for commenting (in advance).
