Big and bad and built for heavy-duty sound, Alpine's SWR-1242D 12" subwoofer delivers high-impact bass that you can hear and feel. Alpine has taken the best features from its previous SWR Series subs and added the hottest technology for ground-pounding power and superb accuracy.
The pulp cone has been reinforced with Kevlar® (the material used in bulletproof vests) for extra rigidity, so it won't buckle under hard play. A rubber surround helps to maximize cone travel for deep bass, while withstanding the decay that can destroy a speaker. A redesigned thermal management system and aluminum airflow motor cover shed heat quickly for efficient operation and better power handling.
The 2" dual 4-ohm voice coils are big enough to handle lots of power while offering system wiring flexibility. The tinsel leads are virtually unbreakable — they're woven into the dual progressive Nomex spiders. An aluminum diecast frame provides a secure, non-resonant housing. The SWR-1242D is designed for use in sealed or ported enclosures.
