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

Alpine X-W12D4 12-Inch Dual 4 Ohm 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 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. 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 ing screws and locking the optional grille into place.
