This manual provides information on the features and
installation of the ND4 and ND8 Neodymium Tweeters
and high pass crossovers.  We suggest you save this
manual for future reference.

We strongly recommend you have your Authorized
Rockford Fosgate Dealer install the ND4/ND8 Neody-
mium tweeters.  If you do choose to install the tweeters
yourself, please be sure to read the entire manual
before beginning.

This section describes the design and features of each
component in the ND4-XFM/ND8-XFM system.

The TX-184N/TX-188N High Pass Crossover is de-
signed to enhance the performance capabilities of the
ND4 and ND8 Neodymium Tweeters. This compact
crossover is designed to conform to the following crite-
ria:

High pass crossover network centered at 4kHz.

Straight forward 3rd order (18dB/octave) filter with a
Butterworth transfer function

Small size, accomplished by inductors wound on a
high temperature nylon bobbin with an air core.

Mounting the TX-184N and TX-188N is accomplished
with the use of .110" & .205" Faston connectors. These
connectors are gold-plated to eliminate the possibility of
corrosion that can cause signal deterioration.

The TX-184N/188N is mounted to relatively flat sur-
faces with sheetmetal screws inserted into the mount-
