Redesigned for better sound

The S-W8D2 8" sub handles up to 300 watts RMS, so you can drive it hard without any worries. The redesigned cone combines carbon fiber and polypropylene for light weight and sturdiness, while its rubber High Amplitude Multi-Roll (HAMR) surround enables maximum excursion for impressive performance. Handy jumpers make it simple to switch from 1-ohm to 4-ohm impedance to adapt to your system. This sub is equally suited for ported or sealed boxes, so you can enjoy your bass big and boomy or tight and precise. A twist-lock mounting system makes it easy to add one of Alpine's specially-designed speaker grilles (sold separately).

Product Research

Features

Progressive Spider: The progressive spider has reinforced layer tinsel leads to ensure reliable and consistent control of the tinsel leads and eliminate any mechanical noise or interference often seen in high excursion cone designs.

Compound Radius Curve Pole Geometry: Alpine's Patented Compound Radius Curve extended pole geometry ensures a symmetrical magnetic field, while optimizing flux density to reduce distortion and further improve power handling and output.

Dual Voice Coils: For system flexibility, the woofer has two 2Ω voice coils. When the voice coils are wired in parallel, the woofer presents a 1Ω load. When the voice coils are wired in series, the woofer presents a 4Ω load.

Spring Terminals: The spring post terminals are all located on one side of the woofer. The terminals will accept pin connectors, single banana plugs, or bare wire up to 8-gauge.

Jumpers: Included with the woofer are two voice coil terminal jumpers. These jumpers allow you to easily wire the voice coils in parallel (for a 1Ω load) or series (for a 4Ω load).

Enclosure:

  • Sealed Box: Alpine recommends a sealed enclosure with an internal volume between 0.18 and 0.53 cubic feet, with an ideal volume of 0.3 cubic feet. Sealed enclosures provide the most control over a woofer, will handle a lot of power, and provide accurate sonic reproduction, making them suitable to all types of music.
  • Ported Box Volume: The recommended ported box volume ranges from 0.38 cubic feet to 0.73 cubic feet, with the ideal size being 0.61 cubic feet, using a slot port measuring 7" (W) x ¾" (H) x 15½" (L).
