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.
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.

Alpine X-W12D4 reviews
As an car audio fanatic and MECP certified installer. Big improvement compared to the old type X (from back when) and against other subs as well. I'm overall impressed with the sound quality, design, and price range. Very well rounded with all types of music, not muddy sounding, and definitely good SPL output with the right spec enclosure. Highly recommend
Pros: clean design, great sound quality, good price.
Cons: nothing at the moment.

These speakers will blow your mind, I have a buddy of mine that has 4 sundown spl subs that can compete with 2 of these alpines these are the best subs on the market right now. I'd get them when you have the money mine get to 136db of bass with just 2 of them.
Pros: Spl, beats competition alot of the time very proud owner to have these getting more soon

Probably the best subwoofer on the market under 1000$. I had previously Alpine SWR-12D2 in my car and loved that subwoofer! But the new Type-X is better on everything! It is mounted in a closed box of 28l, and I give it about 2000Wrms. And it's wonderful, it plays all sorts of music, rock, pop, does no matter how deep or how hard it's just rocking! It's a keeper :)
Pros: SQ meet SPL, Can play LOUD, still very accurate, plays all sorts of music. Handle a lot of power.
Cons: Nope, nada :)

These speakers sound amazing after pro install. Have pair in sealed box and they work beyond expectations. If your in the market for new subs these should be at the top of your list.
Pros: Great sound Fair price Excellent build quality

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).
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.)
