Key Features

Alpine 12" XSeries Subwoofer Dual 4Ω 2700W - Alpine Car Audio X-W12D4

With Alpine X-Series subwoofers, you get the top of Alpine’s subwoofer technology for massive and accurate bass output. These flagship subs have been engineered and tuned with highest precision and use highest grade materials.

The New X-Series subwoofers were developed from a sound philosophy we call Alpine ID – a focus on highly accurate components built for superior imaging.

A triple stacked magnet surrounds an extended voice coil, which allows a very long excursion resulting in huge air movement. A specialized CRC pole with integrated cooling fins and an aluminum shorting cap reduce the lag of coil’s alternating movement while also providing cooling within the motor.

The cone structure is suspended by two spiders and our patented H.A.M.R. surround. The stability of the dual-spider along with the even unfolding of the multi-roll surround create incredibly linear cone travel, free of any unneeded movement that cause distortion.

  • Alpine ID Sound Quality

  • 900W RMS, making it a perfect match for the X-Series X-A90M 900W mono amplifier (when running at 2ohms)

  • 24mm linear Xmax (1 way), 48 mm peak to peak 

  • Dual spiders for precision control over the large dynamic range 

  • Dual shorting rings for strong motor control ensuring low THD and tight bass 

  • Centre pole radial heat sink which wicks heat away from the voice coil and transfers it outside the motor, for long term high output

  • The biggest HAMR surround yet, for linear cone movement throughout its large range of excursion, light but rigid pulp/mica cone which allows for highly accurate bass with great natural tone

  • Twist-lock Trim ring with full mesh grill included
