Details

Alpine’s specially engineered 10″ enclosed Subwoofer boasts a compact ultra-slim wedge-style design. The SBT-S10V is a perfect fit for all applications to fit in small spaces without sacrificing quality and big output. Perfect installation into vehicles with limited space such as utes SUV’s and Pick Ups.

Premium sound quality is achieved with four unique Alpine subwoofer technologies. Radial vented VC heat sink & airflow management system that actively manages voice coil temperatures, FEA optimised dual-sided machined CRC structure creating a symmetrical magnetic field which greatly reduces distortion, FEA optimised injection moulded TPE spider with pass through gap design providing mechanical clearance needed for over 50mm of peak-to-peak excursion and FEA optimised HAMR surround allowing the suspension system to create accurate, distortion-free control at extreme excursions.
