The overbuilt motor and high-controlled suspension in the X-W10D4 allows a small box requirement that can be either sealed or ported based on the desired bass experience. The X-W10D4 has a twist-lock trim ring for easy attachment to the included metal mesh grill. The locking trim ring features an Alpine logo and conceals the mounting screws for a premium fit and finish to your subwoofer enclosure.
The X-W10D4 was built to handle the loudest music and roughest ride. The subwoofer has a cast aluminum frame and HAMR rubber surround that supports and protects the pulp-mica cone so the subwoofer can move a large quantity of air yet maintain its accuracy.
Alpine took the guesswork out of complete sound system building with Alpine Image Defined (ID), an approach to creating sound system “families” that include matching core components that complement each other for the ultimate sound imaging.
The X-W10D4 can we wired in parallel for a 2Ω to get the most optimized performance from the X-A90M Mono Power Density Amplifier for the best results in your sound system. With 900-watts RMS of power performance, the X-W10D4 benefits from the clean output and low distortion of the X-A90M for the most accurate sound imaging.
