About the Infinity Kappa Perfect 12.1
The Infinity Kappa Perfect 12.1 12" subwoofer joins together a rugged aluminum cone and high-roll butyl-rubber surround to produce impressive bass all the way down to 18 Hz. The ultra-rigid woofer cone won't distort (even when you push it to the max), but it's light and responsive for remarkably high sensitivity. That means it'll squeeze the most volume out of the power you feed it.
The massive cast-aluminum basket and the pole-piece are vented, so the 4-layer voice coil stays cool when the music gets hot. Infinity subjects these subs to the most intensive testing in the industry 100 grueling hours of performance at their full RMS rating (350 watts).
The Perfect 12.1 bridges the gap between subs intended for SPL and those intended for sound quality, creating bass that hits hard and sounds great. Whether you're planning a competition system or just looking for powerful bass, this sub's ready for action.Details:

Curvilinear Aluminum Cone: The curvilinear aluminum cone is lightweight and extremely rigid for low distortion and superior bass response.
High-roll Butyl Surround: The high-roll butyl surround damps cone resonance and ensures longevity.
Cast-Aluminum Basket: The non-resonant cast aluminum basket ensures perfect alignment of the speaker's moving parts.
Flat Uniform-roll Spider: The spider design provides maximum control over cone motion at the limits of the speaker's excursion, and reduces even-order harmonic distortion compared to cupped spiders.
Vented Pole Piece: A flared, polished and vented pole piece is used to provide optimum cooling of the voice coil and minimize turbulence.
1.5" 4-layer Voice Coil and Stacked Magnets: The 1.5" 4-layer voice coil and stacked magnets provide high motor force and room for ultra-long excursion.
Gold-plated 5-way Binding Posts: The gold-plated 5-way binding posts will accept pin connectors, spade connectors, banana plugs, dual banana plugs, and bare wire.
Recommended Sealed Box Volume: Infinity recommends a sealed enclosure with an internal volume of 1.0 cu/ft.
Recommended Ported Box Volume: Infinity recommends a ported enclosure with an internal volume of 1.75 cu/ft. One 4" diameter x 12.33" long port should be used with a 1.75 cu/ft enclosure.
Recommended Sealed Bandpass Box Volume: Infinity recommends a bandpass enclosure with an internal volume of 3.45 cu/ft. The 3.4 cu/ft enclosure should have a sealed chamber volume of 2.2 cu/ft and a ported chamber volume of 1.25 cu/ft. One 4" diameter x 10.7" long port should be used in the ported chamber.
Free-air Mounting: In addition to being compatible with sealed, ported and bandpass enclosures, the woofer can be used in free-air applications. A free-air subwoofer is designed to be mounted on a baffle board, which separates two areas of the vehicle. For instance, you could mount this woofer to a board attached to the rear deck or placed in the trunk against the rear seat. The trunk acts as the enclosure housing the subwoofer.
I really think this is the best sub ever made. It can handle unbelievable amounts of power but doesn't need much. It has a remarkable build quality which allows it to sound very musical whyle still thumping in your chest. OUTSTANDING subwoofer wish they still built them to this quality!!!!!
