ND4 AND ND8 NEODYMIUM TWEETERS
ing holes on either side of the enclosure.
The ND4 and ND8 Neodymium Tweeters are designed
for optimum smooth frequency response. This goal, as
with all other Rockford Fosgate products, is achieved by
utilizing "high quality, high-end" components.
The high ionic compound of neodymium enables a
smaller tweeter magnet assembly to be used as op-
posed to the much larger ferrite magnets that are com-
monly used in speaker manufacturing.
The tight tolerances of the neodymium tweeter call for
ferrofluid as the ideal cooling agent, thereby giving the
tweeters an increased efficiency and power handling.
The design of the ND4 and ND8 Neodymium Tweeter
enables you to incorporate the tweeters in either a flush
mount or surface mount installation.
The voice coil in the neodymium tweeter is replaceable
if it should ever fail. Instructions for replacing the dome
are found on page 7.
