Peavey 1501-4dt kevlar cone?

[emil noothout]

Someone did post a question if the Peavey 1501-4dt speaker ever was made with a kevlar cone, and how it could be recognized. When trying to delete a double post of myself it seems i deleted the whole topic, my excuses.

Anyway: My Session 400 limited came with this speaker, and i asked Mike Brown from Peavey about it. He told me the 1501-4dt had a kevlar cone, and Peavey also made the 1501-4sb (shallow basket), which had a paper cone. My understanding always has been: dt=kevlar, sb=paper, but i've seen conflicting information on the web.
The sb-cone is less deep, other then that i see no difference.
