FEATURES  
SPL 6 Midrange / Woofer  
The SPL 6 is an excellent performer with a combination of high  
sensitivity, solid bass and smooth response throughout the audible  
range.  
· Lightweight Cone designed for good rigidity and high sensitivity  
· 2 Ohm Voice Coil for increased output  
SPL 1 Aluminum Dome Neodymium Tweeter  
The SPL 1 tweeter is a high performance 1” Neodymium tweeter  
designed to deliver outstanding high frequency reproduction.  
· Black Aluminum 1" dome for improved power handling and  
linear response  
· Ferrofluid-immersed Voice Coil enhances heat dissipation  
· Vented Aluminum Voice Coil Former for superb heat dissipation  
and high power handling  
SPL 6X Passive Crossover Network  
The SPL 6X crossover consists of high quality, multi-element  
components with a two position tweeter level control. This allows  
tailoring high frequency output to the installation and individual  
preferences.  
· 24 dB/octave Acoustic Summation Crossover Slopes  
· Variable tweeter control for added flexibility  
· Dynamic tweeter protection allows for improved power handling  
and continuous output  
· Ultra-low DCR Inductors for minimal signal loss (High power  
Ferrite in woofer path)  
2 Ohm Nominal System Impedance  
The 2 Ohm impedance design of the SPL 60 system provides an overall  
3 dB increase in output compared to a 4 Ohm design.  
· Effectively a doubling of Sound Pressure Level -- withthesame  
amplifier voltage output  
· More stable, phase coherent load than two 4 Ohm speakers  
operating in parallel

LOCATION  
AND  
MOUNTING  
The first step in a successful installation is thorough  
planning. Choose the location for your speaker  
components carefully. Follow these suggestions to  
ensure proper imaging and the best performance:  
· Select a location where each tweeter and  
midrange/woofer can be mounted close to each  
other. A good rule of thumb is a maximum of  
one foot from cone to tweeter.  
· Choose  
a
location that offers the least  
obstruction of sound to your ears.  
· Try to mount the components on the same plane.  
· Always check behind the chosen mounting  
locations to make sure that there are no  
obstructions (e.g., trunk springs, gas tank,  
window tracks) or wires in the way, as well as to  
make sure that there is ample support on which  
to mount the components.  
INSTALLING Flush Mounting:  
THE  
TWEETER  
1) Cut a 2 1/16” (52mm) diameter hole through the  
mounting surface. If the surface is covered with  
cloth or carpet, be careful not to tear or pull the  
material. Sometimes it is a good idea to peel the  
material away, and then trim it by hand.  
2) Secure the cup in the mounting cutout by using  
the spring clips and screw provided. Slip the  
spring clips through the bottom of the cup and  
tighten the screw until the cup is firmly seated.  
See Figure 1.  
3) Once the cup is secure, mount the tweeter into  
the cup making sure to first pass the tweeter  
wires through the openings in the cup. Turn the  
outer swivel ring, (not the tweeter) clockwise to  
lock it into place. See Figure 2. The tweeter  
may be tilted approximately 15 degrees to  
optimize dispersion and imaging.

Surface Mounting:  
1) Drill one 5/16" diameter hole for the tweeter lead wires and two pilot  
holes for the mounting screws.  
2) Attach the surface mount plate with two flat head screws.  
3) Pass the lead wires through the hole. See figure 3.  
4) Engage the locking holes on the back of the tweeter onto the tabs on  
the plate and rotate counter-clockwise until locked. See figure 4.

The SPL 6 Midrange/Woofer can be mounted on  
the front or rear of a panel; gaskets are provided  
for both options. The bolt hole configuration will fit  
a variety of American, European and Asian OEM  
patterns making it ideal for direct placement. Best  
performance is achieved when the speaker is  
securely mounted to a door panel or rear deck.  
There should be no gaps between the speaker and  
the mounting surface, as this will impair its low  
frequency performance. Be certain that both the  
panel and the speaker are securely mounted to  
prevent unwanted vibration.  
INSTALLING  
THESPL6  
MIDRANGE/  
WOOFER  
1) Mark the speaker location by using the  
template provided.  
2) Cut the opening and debur the edges with a  
file.  
3) Hold the speaker in place against the  
mounting surface and mark the mounting bolt  
holes.  
6) Drill the appropriate size hole for the screws  
provided.  
7) Place the SPL 6 into the trim ring, make the  
speaker wire connections, then install the  
speaker/trim ring assembly to the panel using  
The SPL 6X Passive Crossover can be mounted  
in virtually any location inside the vehicle. Be  
sure not to mount the SPL 6X outside the vehicle,  
or in a location where it may be exposed to dirt or  
moisture (e.g., the engine compartment, inside a  
wheel housing, at the bottom of a leaky trunk,  
inside a door).

LEVEL  
CONTROL  
The SPL 60 system has been designed to provide  
optimum sound in a variety of installation locations. The  
provided crossover allows for 2 positions of tweeter  
level control, 0dB and -3dB. A switch under the plastic  
crossover cover sets one of the two positions. The  
factory setting is 0 dB.

SPL 6 Wiring Diagram  
WIRING  
Figure 6 shows a diagram illustrating the wiring of the  
SPL 60 Component Speaker System. It is important to  
make sure that all connections are in phase; that is  
positive (+) is connected to positive (+), and negative (-)  
is connected to negative (-) since an out-of-phase  
connection will cause a dislocated image and low bass  
output.  
We suggest using premium cable.  
The  
connectors provided with this system will accommodate  
wire from 12 gauge to 16 gauge.
