Set the woofer in the installation hole. If you are mounting the woofer to a hard surface, such
as wood or metal, install a rubber gasket around the periphery of the mounting hole. Align
the screw holes and drive in the six mounting screws. Gradually, tighten each in turn until the
speaker is well seated. Take care to not over-tighten the screws. When the woofer is properly
mounted install the metal grille in the speaker frame.
The crossover installation location should be reasonably accessible to allow easy connection of
the wires and easy adjustment of the controls. If the crossover must be mounted in an
inaccessible location make the speaker wire connections and the control adjustments before
the final installation.
The current which flows through the inductors in the crossover creates a magnetic field
around each coil. If the two crossovers are mounted close to each other, the magnetic field
surrounding one crossover can be picked up by the other, affecting the sound quality of the
other channel. Also, ferrous metal adjacent to the crossover, such as the steel frame of the
vehicle, will negatively affect the operation of the inductors. While these effects occur with all
crossovers, the extreme transparency resolution of the 336PX system may allow these effects
to be heard more readily than with lesser loudspeakers. Therefore to deliver maximum
performance we recommend planning your installation so that the 336PX crossovers are
mounted as far apart from each other, and as far away from steel panels, as possible.
Mounting the 336PX crossover network requires four holes on a flat or nearly-flat surface. Set
the crossover in the installation location and use it as a template to mark the mounting screw
hole locations. Due to the size and weight of the crossover, #10 or 6mm hardware is
recommended.
As before, do not over-tighten the mounting screws; this is especially important if the
mounting surface is not perfectly flat.
Polarity
It is essential to maintain consistent phasing (polarity) for all amplifier-to-crossover and
crossover-to-speaker connections. The important thing is to be consistent in the way you make
every speaker, crossover and amplifier connection. Depending on the relative locations of the
woofer and tweeter to the listening position, the smoothest response may sometimes be
achieved with the tweeter polarity reversed. A switch is provided on the crossover for this. In
all cases, the left and right channels connections and adjustments should be identical.
