Type-R Technology

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.

More Bass, Less Space

The SBR-S8-4 is compact and very shallow (only 11.5" Wide x 19.35" long x 5..5" deep) allowing it to be mounted in virtually any vehicle. This compact subwoofer system works well under or behind the seat of a pickup truck, in a sedan trunk, or in the hatch of an SUV.

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.
