About the Infinity Reference 1242w
Infinity Reference subwoofers add a strong jolt of bass to your system at an affordable price. Their solid construction and innovative basket design provide extended low-frequency response and excellent power handling.
The Reference 1242w 12" subwoofer features a polypropylene cone, suspended in a large-roll rubber surround that absorbs distorting vibrations for cleaner sound. A progressive spider design applies more force to the cone as it travels to its limit, for superb control in extreme conditions.
Integrated venting cools the sub's internal parts for increased reliability, while the aggressively-styled basket minimizes depth while allowing plenty of woofer excursion. The 1242w's dual voice coil design gives you plenty of options when wiring up your system.

Enclosure Compatibility
Dual Voice Coils: For increased system flexibility, the woofer has two 4 ohm voice coils. When the voice coils are wired in parallel the woofer presents a 2 ohm load. When the voice coils are wired in series the woofer presents an 8 ohm load. In addition, each coil may be connected to a different amplifier channel and each channel will see a 4 ohm load.
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 Basket: The unique in-board motor structure reduces the overall mounting depth, without limiting enclosure options.
Vented Polepiece: The vented polepiece provides additional cooling of the motor structure, 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 up to 10 gauge.
Note: The binding posts are positioned too far apart to accept dual banana plugs.
Sealed Box Volume: Infinity recommends a sealed enclosure with an internal volume of 1.25 cu/ft. Sealed enclosures provide the most control over a woofer, will handle more power, and provide more accurate sonic reproduction, making them suitable to all types of music.
Ported Box Volume: Infinity recommends a ported enclosure with an internal volume of 2.0 cu/ft with one 4" diameter x 12.25" long port. Ported (or vented) enclosures provide better efficiency in the 40-50Hz range, and are suitable for use with small amplifiers, giving you more bass output from less power. However, this efficiency comes at the expense of sound quality at low frequencies (40Hz and below), and control.
Bandpass Box Volume: Infinity recommends a 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. Bandpass enclosures often provide the most output available from any amplifier and subwoofer combination at the expense of sonic accuracy. If sheer SPL is desired most, a bandpass enclosure is recommended.

These subs are so clean its sick. I hooked them up to my Infinity 7541a amp and was floored when I heard em hit. They have the ability to make your ears bleed if you let em. If your looking for BIG, BIG bass at a really reasonable price then this is the sub for you.
