Alpine ID: Solving what's missing in most car audio systems these days: great spatial imaging and depth of sound stage. 24mm Xmax is best in class and allows close to 2 inches of full cone motion. Dual spiders ensure a rigid moving assembly while the HAMR surround provides long linear travel. Alpine X-W10D4 10-Inch Dual 4 Ohm Subwoofer CTA-2031 Specifications: 900W RMS, 2700W Peak 4 Ohm 900W RMS makes it a perfect match for the new X-Series X-A90M 900W mono amplifier 28mm linear Xmax (1 way), 56 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 Frequency Response: 24Hz-200Hz Mounting Depth: 6-3/4 Inch 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. 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.
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. 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.
