Fostex effectively replaced the FE127e with the FF125wk.
It gives up a bit of efficiency in exchange for smoother response and similar bass
extension in a smaller box. The ridged dustcap shape inherited from earlier eSR drivers
(but in aluminum vrs titainium) brings a more extended top.
To new to have a whole lot of enclosures developed as of yet, it works in the Frugel-Horn
Mk3 as well as a whole series of Fonkens we have designed for it.
