Product Description

Description:

With an ultra-shallow subwoofer design and powerful sound output, the R-Series Shallow Subwoofers give you the best of both worlds in size and sound.

Ultra-Shallow Design - Alpine's R-Series Shallow Subwoofer delivers the same fun and loud sound you've come to expect, now in a shallow subwoofer that's designed to fit in most vehicle applications.

Extreme Output - Don't let the size fool you - the enclosures feature the same motor movement (20MM of 1-way excursion) as the full-size R2-Series Subwoofers for extreme output in a shallow woofer design.

Reliable Performance - Integrated cooling fins located in the core of the subwoofer help dissipate the heat generated by the large 4-inch voil coil for enhanced cooling reliability and hours of uninterrupted playtime.
