The SBR-S8D4 features Alpine’s Type-R 8″ subwoofer in a custom slot ported enclosure. Ideal for installation in small spaces, its compact size means it can fit virtually anywhere.

The pre-installed subwoofer employs many features typically found in larger models, such as Alpine’s H.A.M.R (High Amplitude Multi Roll) suspension. This unique design allows greater linear excursion while improving control, to achieve maximum output and outstanding sound quality.

Designed to achieve optimal output, the carpeted enclosure features heavy duty MDF construction. Plus, stylish brushed aluminium laminate and a robust grill create the perfect balance of stunning aesthetics and practicality.
