Alpine SBS-S15D4

The SBS-S15D4 combines the new Type-S 15″ Subwoofer with a perfectly matched slot ported enclosure, precisely designed and engineered in the USA. Featuring Alpine’s HAMR (High Amplitude Multi Roll) surround previously only found on Type-R and Type-X subwoofers, the new Type-S subs play louder and lower than ever before. Plus, improved power handling and an advanced airflow system mean they can produce more bass non-stop. With an aluminium look cone and stylish carpeted box, this subwoofer in enclosure looks as good as it sounds.
