More bass, less space
The SBR-S8-4 uses the same 8” subwoofer available in the Type-R component subwoofer lineup, so you get high excursion combined with high power handling. This advanced Type-R motor structure converts your amplifier’s output to low bass you can feel.
Tuned to rock
In order to play low with minimal power input requirements, the SBR-S8-4 is ported. A low tuning frequency combined with an efficient, large cross-section port allows the system to play down to the lowest octaves while still maintaining excellent control and power handling characteristics.
Killer cosmetics
High-quality carpeting and sleek laminate combine to give the SBR-S8-4 great looks. A strong, attractive Type-R grille protects the woofer’s cone from damage, and the flush-mount spring-loaded terminals make connecting large-gauge wire a snap.
Durable construction
Unlike many low-cost enclosures, the SBR-S8-4 is constructed from the best materials. High-quality MDF is used for all structural components, and it is internally braced to add stiffness and durability.
Amp it up
350 watts of RMS power handling make the SBR-S8-4 compatible with a wide range of mono and multi-channel amplifiers. For example, hook it to the subwoofer channel on the 5-channel Alpine MRX-V60, or connect it to two bridged channels on an Alpine MRX-F30…either way you’ll get great low-bass performance.
