Alpine ID is short for the new Alpine global sound culture with an evolutionary approach for solving what’s missing in most car audio systems these days: great spatial imaging and depth of sound stage. It centers on developing matched sound systems with core components that work together to achieve greater realism in the sound stage while maintaining great dynamic range and accuracy. The new X-Series subwoofers underpin Alpine ID sound philosophy.

A triple-stacked magnet and extended voice coil allow for a very long excursion resulting in huge air movement. A specialised CRC pole with integrated cooling fins and an aluminium shorting cap reduce the lag of the 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 causes distortion.

The 24mm X-max is the best in its class and allows close to 2 inches of full cone motion. In order to create a powerful yet accurate subwoofer, Alpine has implemented 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.

The powerful and efficient motor coupled with its highly-controlled suspension gives the X-Series subwoofer the ability to create loud and accurate bass in a very small, sealed box. Only requiring 15.6 l of air space, the 10” 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.

Taking design cues from tweeter development, Alpine has incorporated 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 X-Series amplifier X-A90M is the perfect amplifier for the job. Along with the 900W power-matched specifications of both components, each was built under the same sound philosophy. With a focus on musicality and sound imaging, the X-W10D4 is complimented by the amplifier’s clean, low distortion output and >1500 damping factor. Add the X-Series speakers to the system and prepare to experience a new level of in-car imaging.
