Rockford Fosgate FNX-1405, FNX-1406F, FNX-1404 manual Midrange

DESIGN FEATURES

Midrange

4.Rubber Surround – The durable rubber surround withstands the extremes of the automotive environment. It also improves sound quality by reducing 2nd and 3rd order harmonics and provides wider frequency response.

5.Mica Filled Polypropylene Cone – The ideal cone material would be infinitely strong, very light and would have very high damping to ensure great sound quality. The Fanatic X Series Component Systems use a mica filled polypropylene cone that is strong, light and has high internal damping to provide excellent reproduction of sound.

6.Cupped Spider – The spider has the job of centering the voice coil and providing the rear suspension for the speaker. The Fanatic X Component Systems use a durable cupped spider to ensure great sound with long life and durability.

7.Large 1" Voice Coil with Anodized Aluminum Former – Just like all Rockford Fosgate woofers, all Fanatic Component System midrange drivers use an aluminum voice coil former for more efficient dissipation of heat. Dissipating the heat is key to long life and high power handling, so go ahead and crank it up!

8.Vented Pole Piece – The pole piece extends from the back of the speaker into the voice coil area. The Fanatic X Component System uses a vented pole piece to allow cool air to circulate in the voice coil gap which allows greater power handling and increased reliability.

Crossover

9.2 Way Butterworth Crossover – Features an 18dB per octave high-pass crossover for the tweeter and a 6dB low-pass crossover for the midrange. The steeper slope of the tweeter crossover gives better power handling. The low-pass crossover provides a seamless transition between tweeter and midrange.

10.Optical Compression – This built-in protection circuit limits power to the tweeter when the “danger” threshold is exceeded. Because it simply limits power and doesn't shut the tweeter off, this circuit is completely inaudible.

11.Gold-Plated Screw Terminals – Terminals plated in gold for maximum resistance to corrosion to ensure great sound for years to come. These terminals accept bare wire or 1/4" spade lug connectors.

12.0dB/–3dB Tweeter Pad – In some installations, you may find that the tweeter location is much closer to your ears than the midrange. This pad allows you to match the tweeter level to the midrange for the best balance.
