Made To Crush The Competition

Both the TS-300D4 and TS-300S4 are in a league of their own, capable of handling a tremendous amount of power to achieve louder and punchier bass than anything out there. More importantly, this is achieved without the slightest hint of distortion, thanks to clever design features like double-stacked magnets.

Unparalleled Reliability

An innovative dust-protection construction helps shut out dust, one of the most common causes for accelerated wear and tear in a car environment. This not only greatly enhances these subwoofers’ long-term reliability, but also guarantees a more consistent performance over time.

Stylish And Easy To Install

The TS-300D4 and TS-300S4 are head-turners with their brushed-metal accent, clean lines, and symmetrical design. They are compatible with a variety of enclosures, ranging from 24.1 litres to 49.6 litres in capacity, for greater installation flexibility.
