Sub is in excellent working condition. I am an audiophile, I take care of my equipment. This sub hits HARD. One of the alpine classics! I may ship depending on the location.
Big and bad and built for heavy-duty sound, Alpine's SWR-1522D 15" 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 standing up to the decay that can destroy a speaker. Air vents help the sub shed heat quickly for efficient operation and better power handling.
The two voice coils handle lots of power while offering system wiring flexibility. The tinsel leads are virtually unbreakable — they're woven into the spiders. An aluminum diecast frame provides a secure, non-resonant housing. The SWR-1522D is designed for use in sealed or ported enclosures.
