Yup,
Just went downstairs to look, and I too have the solid driver w/ no black insert in my brand new 350.
Looks just like the driver in the 500, in the same chassis as the 350.
I wonder if this has something to do with why I am so confused about my reaction to this sub, which I think is just awesome, while so many other posters seem to think it is a bit under-powered compared to the 500 and other subs out there?
