Recommended Sealed Bandpass Box Volume: Infinity recommends a sealed bandpass enclosure with an internal volume of 2.5 cu/ft. The enclosure has a sealed chamber volume of 1.25 cu/ft and a ported chamber volume of 1.25 cu/ft with two 4" diameter x 8" long ports.

High-efficiency Polypropylene Woofer Cone: This lightweight and popular material is used to ensure maximum woofer efficiency. The benefit is high output with modest amplifier power.

Large-roll Rubber Surround: The large-roll rubber surround provides optimum cone-edge suspension and absorbs distortion that may travel up the cone edge, ensuring clean, tight bass.

Proprietary Deep-draw I-beam Basket: The deep-draw I-beam design allows room for a longer motor structure, which provides increased bass output. This basket is also more rigid and has a lower basket resonance.

Vented Polepiece: The vented polepiece provides additional cooling of the motor structure. The subwoofer's thermal capabilities are augmented, thus increasing power handling.

Progressive Spider: The subwoofer uses a progressive spider, which provides better control at excursion limits than more commonly used linear spiders. The result is reduced distortion at high output levels.

Gold-plated Binding Posts: The gold-plated binding posts will accept pin connectors, spade connectors, banana plugs, and bare wire.

Note: The binding posts are positioned too far apart to accept dual banana plugs.
