Alpine X-W10D4 10′′ X-Series Subwoofer (4Ω + 4Ω)
Alpine’s all-new X-Series subwoofers bolster the X-Series Hi-RES amplifier and speaker line—to create the ultimate unified audiophile sound system. The X-Series subwoofers draw upon decades of Alpine engineering, expertise and precision manufacturing that culminates; to deliver a new of level build quality, design and finesse to produce a subwoofer with the highest calibre of bass fidelity and extreme output.
X-Series are like no other, harvesting bass performance beyond the limits and measures of their nearest rivals.
Alpine Image Defined
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 centres 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 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.
Built to move tons of air
The 24mm X-max is 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.
All new motor design
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.
