Hi, JBL experts
I did some study on 4365 recently,i found it may be a very nice choise!
To my surprise, it uses 4' 476Mg compression driver as HF!and more,it uses cotton surroud instead of rubber surrond as 4338/4348 9800 do.
I think rubber surrond is very hard to push and control,and its sound is not so nature as foam and cotton surrond,(BTW i don't like rubber surrond at all.)
I appriciate your review.
