12′′ (30 cm) X-Series Subwoofer (4Ω + 4Ω)

Alpine introduces the all-new X-Series of high-grade speakers, subwoofers and amplifiers. These products have been engineered and tuned to create a perfect match for extraordinarily dynamic, realistic sound reproduction and a spatial sound impression. 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.

Introducing the ultimate subwoofer

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.

Overview

  • Alpine ID Sound Quality
  • 900W RMS, making it a perfect match for the X-Series X-A90M 900W mono amplifier
  • 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
  • Center 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

Built to move tons of air

The 24mm X-max is best in class and allows close to 2 inches of full cone motion. In order to create a powerful yet accurate subwoofer, we had to implement several technologies that keep the cone under control. Dual spiders ensure a rigid moving assembly while the HAMR surround provides long linear travel. A shorting ring keeps the THD down while a custom heat sink integrated CRC pole and shorting cap keeps high magnetic force. These design aspects come together to produce incredibly precise, powerful bass.

All new motor design

The powerful and efficient motor coupled with its highly-controlled suspension give the X-Series subwoofer the ability to create loud and accurate bass in a very small, sealed box. Only requiring 28.3 l of air space (15.6 l for the 10”), the 12” X-Series subwoofer can reproduce frequencies down to 40 Hz before rolling off, leaving you with bass that digs deep and plenty of trunk space.

Easy grille and trim ring included

Taking design cues from tweeter development, we’re incorporating a twist-lock trim ring which allows easy attachment of the included metal mesh grill. With a simple twist, the trim ring locks into place, concealing the mounting screws and locking the optional grille into place. The trim can be installed with or without the grille.
