RS-W12D2

For those looking to add powerful, hard-hitting bass performance to their vehicle but lack the space to add a subwoofer, 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. Don’t let the size fool you – the R-Series Shallow Subwoofers feature the same cone movement (20MM of 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 is controlled by a powerful neodymium magnet for 600W RMS of power handling.

I have had another set of these Alpine Type R in a different vehicle. Not the shallow ones like I am installing in my truck. I had the regular Type r 12" woofers. Man, these things pound hard We're going with them again. Boy these things rock. I am adding a new system to my drive to work truck. So, it's going to be stealth and great sound quality on this build Sundown 200.4 and a 1500.1 Salt amps and two sets of Sundown 2 way 6.5" components. AudioControl DM-608 DSP teamed to an Alpine ILX-409 Double din HU. This is going to be a monster system
