About The Product
Designed for Tight Spaces
Now you don’t have to choose between bass and space! Alpine’s R-Series Shallow Preloaded Subwoofer Enclosure measures at a minimal 5.25” deep to deliver a loud and fun sound in most vehicle applications. Rubber “feet” are adjustable in height to accommodate uneven vehicle floors.
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. At the heart of the R-Series Shallow Subwoofers is an oversized 4-inch voice coil that houses the lightweight and powerful neodymium magnet for 600W RMS of power handling.
