Alpine redesigns their X-Series subwoofers to deliver even more impressive performance. The X-W10D4 10″ subwoofer handles up to 900 watts RMS, so don’t hesitate to give it plenty of juice. This rugged sub features a pulp/mica cone with a parabolic shape that maintains its rigidity and strength for outstanding response and accuracy. The big rubber surround supports the cone in the sub’s cast aluminum frame, while Alpine’s latest technology allows this sub to move an amazing amount of air (28mm Xmax, for you bass geeks out there) at very high levels while staying cool.
