FEATURES SPL 4 Midrange / Woofer The SPL 4 is an excellent performer with a combination of high sensitivity, solid bass and smooth response throughout the audible range.
LOCATION AND MOUNTING The first step in a successful installation is thorough planning. Choose the location for your speaker components carefully.

A good rule of thumb is a maximum of one foot from cone to tweeter. • Choose a location that offers obstruction of sound to your ears.

INSTALLING THE SPL 4 MIDRANGE/ WOOFER The SPL 4 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.
