Special Features


The woofer cones are mica filled polypropylene, a strong, lightweight material with high internal damping to provide excellent sound reproduction.

The spider has the job of centering the voice coil and providing the rear suspension for the speaker. The Fanatic P Component system woofers use a cupped spider to ensure great sound with long life and durability.

A 1" Voice Coil with an anodized aluminum former  for more efficient heat dissipation helps ensure durability and high power handling.


A synthetic fluid (Ferrofluid) is placed in the magnetic gap of the tweeter to aid in the cooling of the voice coil; this results in higher power handling and greater reliability.

Neodymium magnets are used to produce a strong magnetic field, so that a small magnet may be used to enable a tweeter to have very high performance.

The 3/4" dome tweeters come installed in the flush mount sockets. To remove the tweeter from the socket, turn the backplate of the socket counter clockwise, then lift the backplate away from the socket to access the tweeter.

Tweeter Mounting Options: The tweeters may be flush, surface or "wedge" mounted. The tweeters swivel inside the flush and surface mount sockets, but do not swivel in the "wedge mount" socket.  The "wedge mount" sockets surface mount to the vehicle and hold the tweeters at a fixed angle (may be mounted to provide a 15 or 60 degree angle). The tweeters must be installed using one of the three sockets.

Special Features

Crossover Dimensions: 4.397"L x 1.687"W x 0.858"H

The crossovers contain an 18dB/octave, 6.3kHz high-pass network to prevent low frequencies from being sent to the tweeters; full range signals are sent to the woofers (extreme high and low frequencies are automatically rolled off by the woofer according to it's inherent high and low frequency limitations).

Optical Compression Tweeter Protection:This built-in protection circuit limits power to the tweeter when the "danger" threshold is exceeded. Because the circuit simply limits power and doesn't shut the tweeter off, this method of protection is inaudible.

The crossover input wires are bare ended, while the output wires are terminated with quick-slides.

There is one mounting tab on each end of the crossover.

Specifications Note: The manual lists separate sensitivity specs for the woofer (86.8dB) and tweeter (91dB). The sensitivity figure listed in the Crutchfield database is the average of the two individual sensitivity specifications. The average sensitivity (88.9dB) is given  because it more accurately represents the overall sensitivity of the system; this permits a better estimation of the power needed for clean, high volume output.
