The ND4 Neodymium Tweeter is designed for opti-
mum smooth frequency response.
The high ionic compound of neodymium enables a
smaller tweeter magnet assembly to be used as
opposed to the much larger ferrite magnets that are
commonly used in speaker manufacturing.
The tight tolerances of the neodymium tweeter call for
ferrofluid as the ideal cooling agent, thereby giving the
tweeters increased efficiency and power handling.
The design of the ND4 Neodymium Tweeter enables
you to incorporate the tweeter in either a flush mount
or surface mount installation.
The voice coil in the neodymium tweeter is replace-
able if it should ever fail. Please contact your Autho-
rized Rockford Fosgate Dealer for more information.
SPEAKER PLACEMENT FOR PROPER SOUND
STAGING
To create an accurate listening environment one must
first have a basic understanding of sound reproduction.
Rockford Fosgate recommends creating a FRONT
STAGE with ambiance or REAR FILL. The main goal is
to create a three dimensional sound stage that exhibits
width, height and depth. In the ideal listening environ-
ment the main source of sound is in the front of the
listener. This helps to create a front stage. A front stage
describes the systems ability to reproduce the presence
of a stage from in FRONT of the listener. Ambiance or
rear fill is the result of sound reflecting off the rear walls
and other surfaces before traveling back to the listener.
A solid front stage with a good image is one of the most
difficult tasks to achieve in an automobile. No car reflects
the optimum listening environment. This makes proper
