Loudspeaker Raw Driver Measurements
In this page I will publish measurements of loudspeaker raw
drivers, that can be useful to anybody who wants to develop his own
loudspeaker system design.
The Thiele-Small parameters has averaged values for all units I have
(usually a pair). If the difference between the drivers or lots is
significant, it will be specially mentioned. For the response
graphics I choose an unit, that I found as a "representative"
for the particular model.
