TECHNICAL DESIGN FEATURES Silk Dome The silk dome used in the AUDIOphile tweeter allows linear move- ment of the diaphragm and voice coil assembly. The linear movement or “symmetrical control” of the assembly provides smooth and well extended high frequency response. THE RESULT: Smooth response for “audiophile” sound quality. Neodymium Magnets 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 commo

Midrange Features Nitrile Rubber Surround The nitrile material is resilient to temperature variations and provides a consistent support necessary of the linear motion of the speaker cone, In addition, the inherent damping capabilities eliminates the transmission of sonic disturbances between the cone and the frame of the speaker. This greatly improves the clarity of the speaker's midrange frequency response. THE RESULT: Improves speaker's frequency response. Flat Spider The speaker's linea

Powder Coat Finish Powder coating has long been the industry standard for durability in protective metal finishes. A dry powder (non-aerosol) is electrostati- cally applied to the metal and “baked” on to provide a hard “shell- like” finish. As an additional benefit, powder coating is the only finishing process that releases no toxic chemicals into our ozone. THE RESULT: A durable and “earth friendly” metal finish.

Zobel Network The Zobel network compensate for the impedance rise presented by the driver (speaker). The network flattens out the gradual impedance rise produced by the voice coil which typically results in high frequency rolloff. The Zobel Network compensates for this natural rolloff which allows the driver to produce a more linear response up to the tweeter crossover point. THE RESULT: Compensates for natural high frequency rolloff of midrange. Adjustable Tweeter Level Matching The RFA-1

INSTALLATION CONSIDERATIONS Tools Needed The following is a list of some of the tools necessary for the installation of your speakers. Power Drill with assorted bits #2 Phillips Screwdriver Tape Measure Hole Saw (2") Voltmeter General 1. For safety, disconnect the negative lead from the battery prior to beginning the installation. 2. Never run wires underneath the vehicle. Running the wires inside the vehicle provides the best protection. 3. Avoid running wires over or through sharp edges. Use r

MOUNTING LOCATION A solid front stage with a good image is one of the most difficult tasks to achieve in a vehicle. No car has the optimum listening environment. This makes proper sound staging very difficult to accomplish. Most speakers tend to be placed where they will fit easily, as opposed to where they can perform the best. The mounting location of your speakers will have a great effect on the sound quality of your stereo system. The special care taken to place the speakers will yield many

• Sound radiated from a “point source” has the most optimum stereo imaging because the separation of the acoustical centers between the midrange and tweeter for each channel is at the optimum. Figure 2-A describes a horizontal speaker alignment. In a closed environ- ment such as an automobile, horizontal speaker alignment can cause severe amplitude and phase differences which will degrade not only the imaging, but also the frequency response. This is due to the path length differences between th
