Features

Dual Voice Coils: This woofer features dual 4Ω voice coils, offering wiring flexibility. When the voice coils are wired in parallel, the woofer presents a 2Ω load. When the voice coils are wired in series, the woofer presents an 8Ω load.

Break-in Period: The high-performance suspension system makes the speaker very stiff out-of-the-box. Approximately 2 weeks of daily playing will allow the suspension to break-in and reach its optimum equilibrium. A broken-in subwoofer will exhibit stronger bass performance, smoother response, and greater low-bass extension.

Sealed Enclosure Applications: Kicker recommends sealed enclosure volumes from 1.8 ft³ to 5.2 ft³. Sealed enclosures provide the most control over a woofer, will handle a lot of power, and provide accurate sonic reproduction, making them suitable for all types of music.

Ported Enclosure Applications: Kicker recommends ported enclosure volumes from 3 ft³ to 5 ft³. Slot port dimensions are given in the manual for the minimum enclosure volume (15-1/2" x 2-3/4" x 25-3/4") and the maximum enclosure volume (15-1/2" x 3" x 22"). Ported (or vented) enclosures typically provide better overall efficiency than sealed, so they are suitable for use with smaller amplifiers, giving you more bass output from less power. However, this efficiency comes at the expense of very low frequency output.
