I see where Watkins Engineering is again selling the dual voice coil Watkins Woofer. They are $350 a pair and new. The site states they have vinyl cones, but the originals had polypropylene cones. So, I guess this means they aren't like the originals. Should they perform the same. I haven't seen a picture of the new ones so I don't know if they look different or not. Anybody know anything about these two woofers. Thanks.
