About the Alpine X-W12D4

Built to take it

Alpine redesigns their X-Series subwoofers to deliver even more impressive performance. The X-W12D4 12" subwoofer handles up to 900 watts RMS, so don't hesitate to give it plenty of juice. This rugged sub features a pulp/mica cone with a parabolic shape that maintains its rigidity and strength for outstanding response and accuracy. The big rubber surround supports the cone in the sub's cast aluminum frame, while Alpine's latest technology allows this sub to move an amazing amount of air (28mm Xmax, for you bass geeks out there) at very high levels while staying cool.

Versatility

You can wire the dual 4-ohm voice coils to get the optimum performance from your amp, or to configure a custom setup with multiple subwoofers. The X-W12D4 works well in sealed and ported enclosures so you can choose what kind of bass you want to hear and feel.

Note: If you are wiring this DVC sub for lower impedance, make sure that your amp is compatible.

Features

Dual Voice Coils: For system flexibility, the woofer has two 4Ω voice coils. When the voice coils are wired in parallel, the woofer presents a 2Ω load; when wired in series, the woofer presents an 8Ω load.

HAMR: The woofer features a High Amplitude Multi Roll (HAMR) Surround, made of rubber, that allows a large linear excursion and greater SPL. The HAMR design allows extreme excursions without sacrificing valuable cone area.

Dual Progressive Spider: The dual progressive spiders have integrated 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 pole geometry ensures a symmetrical magnetic field, while optimizing flux density to reduce distortion and further improve power handling and output.

Oversized Voice Coil: The oversized (65mm) dual voice coils are wound on an aluminum former.

Terminals: The set screw terminals are all located on one side of the woofer. The terminals will accept bare wire up to 8 gauge.

Jumper Plug: A jumper plug on the terminal block allows you to easily wire the voice coils in parallel (for a 2Ω load) or series (for an 8Ω load).

Enclosure Compatibility

Sealed Box Volume: The recommended sealed box volume ranges from 0.52 ft³ to 1.37 ft³, with 0.97 ft³ being the ideal size. (Most volumes in the manual are given as net, before accounting for the displacement of the subwoofer when installed.)

Ported Box Volume: The recommended ported box volume ranges from 1.12 ft³ to 2.12 ft³. The ideal size is 1.77 ft³, using a slot port measuring 3.75" (Width) x 4" (Height) x 18" (Length). (Most volumes in the manual are given as net, before accounting for the displacement of the subwoofer and slot port.)

Alpine! Stay thirsty my freinds! [ Tim  May 23, 2018 ]
A
It's the top of the line in Alpine subs and the next size down couldn't handle the wattage (amp is 1200W RMS and this sub is 900W RMS). [ John  Mar 04, 2018 ]

Hi Arthur, This is a Dual coil 4ohm sub. This sub can be wired to become 2ohm, there is an instructions on how to wire a Dual 4ohm into 2ohm. I have purchased this sub and I am running it in 2ohms. It sounds great and bumps pretty hard...
[ herbert  Mar 02, 2019 ]
