The Renkus-Heinz DR18-2R is a high-output, powered dual 18-inch subwoofer engineered to deliver exceptional low-frequency extension and impact for large-scale sound reinforcement applications in touring, fixed installations, and high-performance venues. This subwoofer integrates two long-excursion 18-inch drivers into a precisely tuned bass-reflex enclosure, each driven by its own dedicated high-power Class-D amplifier module. This configuration is designed to produce massive acoustic output with tight control and minimal distortion, providing the foundational low-end necessary for modern music, live events, and cinematic experiences. The subwoofer's design focuses on maximizing efficiency and output in the sub-bass region, ensuring that kick drums, synthesizers, and sound effects are reproduced with both visceral physical impact and detailed articulation.

A key feature of the DR18-2R is its comprehensive onboard processing and system management capabilities. The integrated DSP (Digital Signal Processor) provides speaker-specific tuning, including precise crossover filtering, parametric equalization, phase alignment, and advanced limiter protection for both the amplifiers and the drivers. This built-in intelligence allows the subwoofer to be optimally integrated into a larger sound system without the immediate need for an external system processor, although it remains fully compatible with such units for ultimate system-wide control. The processing ensures the subwoofer operates within its safe thermal and mechanical limits, even under demanding operating conditions, enhancing both performance reliability and longevity.

Constructed for professional touring and installation durability, the cabinet is built from high-grade, void-free plywood with extensive internal bracing and finished in a rugged, textured coating. It features integrated handles and robust hardware for transportation, as well as integrated casters for easier mobility. The rear panel provides flexible connectivity with both analog and digital input options, often including line-level XLR inputs and outputs, as well as Dante digital audio networking for seamless integration into modern audio networks. With its formidable combination of dual high-output drivers, powerful dedicated amplification, and sophisticated onboard DSP, the Renkus-Heinz DR18-2R stands as a premium solution for audio professionals who require deep, powerful, and controlled low-frequency reproduction in the most demanding acoustic environments.
