The subwoofer has a rated power of 1500 watts, it has no equal when it comes to overall performance and wiring with other components. Special attention when developing the model was paid to the TS parameters and strict build quality to achieve the highest possible sound pressure. The NITRO subwoofer is quite versatile and will sound great in a wide range of music.

The high-temperature 3-inch 4-layer BASV dual voice coil, with round copper wound on an aluminum former, is combined with a massive 153 oz ferrite motor. This allows for deep, stunning bass at the highest SPL levels. The subwoofer has completely sealed T-Yoke, which increases the endurance and durability of the subwoofer in everyday use. The model integrates an ultra-wide double-stitched surround, in tandem with a competition-grade cone and triple "CONNEX" spider, it sets a new precedent in terms of sound quality and power.
