Alpine SBS-S15D4 Type-S

Type-S 15″ Subwoofer Enclosure

The Alpine SBS-S15D4 combines the new Alpine 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 Alpine SBS-S15D4 subs play louder and lower than ever before.

  • 500W RMS Power Handling

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 Alpine SBS-S15D4 subwoofer in this enclosure looks as good as it sounds.
