BUILT TO MOVE TONS OF AIR

The 24mm Xmax 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.

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.

THE PERFECT PAIR PERFECT POWER MATCHING

The X-Series amplifier, X-A90M, is the perfect amplifier for the job. Along with the 900w power matched specifications of both components, each were built under the same sound philosophy, Alpine ID. With a focus on musicality and sound imaging, the X-W10D4 is complimented by the amplifiers clean, low distortion output and >1500 damping factor. Add the X-Series speaker to the system and prepare to experience a new level of in-car imaging.

  • Handles up to 900 watts RMS (450 watts per coil)
