You want to feel your bass, but you want to hear it, too — and that's what Alpine's top-of-the-line
You want to feel your bass, but you want to hear it, too — and that's what Alpine's top-of-the-line 12" subwoofer is all about. The SWR-1221D 12" dual 2-ohm Type-R sub is designed to handle high power levels and provide the remarkable accuracy and crystal-clear sound that brings music to life.The motor structure and double-stacked magnets focus magnetic energy within the vented pole piece for up to 1,000 watts of mind-blowing peak output. The pulp cone has been reinforced with Kevlar® (the material used in bulletproof vests) for extra rigidity, so it can withstand that kind of hard play. For deep bass, a 1" Santoprene rubber surround aids in cone travel while guarding against decay that can mar speaker output. An extended spider landing area provides extra excursion for fuller sound.The dual 2-ohm, 2" voice coils are big enough to handle lots of power while offering system wiring flexibility. The tinsel leads are woven into the dual progressive Nomex spiders, so you don't have to worry about breakage that can devastate your sound. This design also helps you get nearly 3" of cone excursion for maximum output. An aluminum diecast frame provides a secure, non-resonant housing.The SWR-1221D is designed for use in sealed or ported enclosures.
