The SPL SHOW NITRO series subwoofer was designed to provide the perfect combination of SPL qualities in its power class. The N12-S1500 is capable of delivering deep, stunning and powerful bass sound. 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 140 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.

Dual voice coils
Dual 3-inch 4-layer BASV voice coil with round copper winding on an aluminum frame. The voice coil with higher performance characteristics, which increases the endurance and durability of the subwoofer in everyday use. The double voice coil means double power, double efficiency and excellent result.

Dual ferrite rings
The huge magnet in tandem with the competition-grade cone and triple spider "CONNEX", this component sets a new precedent in terms of sound quality and power.

Competition grade treated paper cone
The NITRO subwoofers range are the most advanced in low bass reproduction. The SPL Show brand subwoofers feature competition grade non-pressed cellulose cones to help prevent resonance, improve linearity and reduce distortion.

Push terminals
High-quality spring-loaded terminals make connecting the subwoofer quick and easy. Install a power cable in fast click of push terminals - then the clamps tightly and securely fix the connection.
