The Nettuno S182 is a high-performance active subwoofer designed to deliver solid low-frequency extension for professional sound reinforcement. Equipped with two 18-inch ferrite woofers, each featuring a double 4-inch voice coil, and driven by a 2000 W RMS amplifier module, the S182 provides substantial output with a usable bandwidth extending from 35 Hz up to the selected crossover point. Its architecture supports clean, controlled low end, making it suitable for both single-unit setups and larger, coupled arrays.

The integrated DSP enables fast deployment with presets that optimize the subwoofer’s behavior in different configurations, whether used in front-of-house systems, cardioid arrangements, or stacked clusters. The enclosure is engineered to ensure stable performance in both mobile and installed environments. With its straightforward connectivity and system-friendly tuning, the S182 is built to integrate smoothly with Nettuno L28 forming a coherent and scalable low-frequency foundation for a wide range of productions.
