FEATURES  
SPL 55 Midrange / Woofer  
The SPL 55 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 voltage sensitivity and higher  
output  
Aluminum Dome Neodymium Tweeter  
The SPL 55's coaxially mounted 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  
Passive Crossover Network  
· The crossover consists of high quality, 2 pole design for improved  
power handling, lower distortion and better imaging.  
· Acoustic Summation design combines the crossover with the  
speaker's natural roll-off for a steeper slope and increased power  
· Dynamic tweeter protection allows for improved power handling  
and continuous output  
2 Ohm Nominal System Impedance  
The 2 Ohm impedance design of the SPL 55 system provides an overall  
3 dB increase in output compared to a 4 Ohm design.  
· Effectively a doubling of Sound Pressure Level -- with the same  
voltage input  
· More stable, phase coherent load than two 4 Ohm speakers

· The first step in a successful installation is  
LOCATION  
AND  
MOUNTING  
thorough planning. Choose the location for your  
speaker components carefully.  
Follow these  
suggestions to ensure proper imaging and the best  
performance:  
· Choose a location that offers the least obstruction  
of sound to your ears.  
· 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.

The SPL 55 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,  
Asian and European 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  
THESPL55  
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 55 into the trim ring, make the  
speaker wire connections, then install the  
speaker/trim ring assembly to the panel using

SPL 55 Wiring Diagram  
WIRING  
The figure below shows wiring for the SPL 55 speaker. 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.
