REFERENC E® THANKYOU for choosing an Infinity® Reference® Series 1000s or 1200s subwoofer. These Reference subwoofers are designed to suit a broad range of car audio applications and can be used in a wide variety of enclosure types to produce extended, powerful bass in a limited amount of vehicle space. To get the most performance from your new subwoofer, it is strongly recommended that you have a qualified professional install your 1000s or 1200s subwoofer.
REFER ENCE ® VENTED ENCLOSURES Avented enclosure acts like a sealed enclosure at frequencies above its tuned (resonance) frequency, At resonance (which is defined by the vent), the vent produces the majority of sound- the subwoofer cone is nearly stationary while the air inside the vent vibrates. This provides greater mechanical power handling at and above resonance, but reduced mechanical power handling below resonance.
REFERENCE® MOUNTING THE SUBWOOFER The 1000s and 1200s subwoofers can be mounted from the outside of the enclosure or from the inside of the enclosure. Which- ever way you mount the subwoofer, use the included foam mounting gasket to ensure a leak-free seal between the subwoofer frame and the enclosure. ~ = 20 I~ ~0 <{?
