Alpine SWR-1242D Subwoofer
Alpine’s SWR-1242D 12″ subwoofer delivers 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.
