the jbl 4312e is entirely diferent then then 4312se.

the 4312e has the XO at 2khz and 5khz https://www.jblsynthesis.com/product.../id_4312e.html
the 4312se has the xo at 600hz and 5khz https://jblsynthesis.com/productdetail/id_4312se.html

the 4312e runs their 12 inch up to 2khz? wtf are they thinking?
is it a typo and they meant to say 200hz rather then 2khz?
