RCF SUB9006-AS Active Dual 18" Subwoofer

High-Output Dual 18 Subwoofer for Touring and Installation
The RCF SUB 9006-AS is a high-performance active subwoofer engineered to deliver deep, powerful bass in live sound reinforcement environments. Featuring dual 18" neodymium woofers with 4.0" inside-out voice coils, this sub handles demanding audio applications with ease, offering 3600W RMS and 7200W peak Class-D amplification. Whether you're outfitting a touring rig or enhancing a fixed install, the SUB 9006-AS provides the low-end punch needed for full-range PA systems, all within a rugged, road-ready cabinet.

Serious Low-End with Precision and Control
With a frequency response extending from 30 Hz to 400 Hz and a maximum SPL of 142 dB, this subwoofer delivers extended bass suitable for electronic music, large-format theaters, concert halls, and touring systems. The DSP-controlled input section ensures consistent performance with built-in presets, adjustable delay, and phase controls—making it easy to dial in your sound for different acoustic environments or speaker configurations. The SUB 9006-AS pairs exceptionally well with line array systems like the HDL50-A or HDL10-A, forming a seamless low-frequency extension.

DSP-Managed Input and Remote RDNet Integration
The intelligent onboard DSP allows for precise signal management directly from the back panel, including gain, phase inversion, EQ curve selection, and output delay settings. For remote monitoring and system tuning, the SUB 9006-AS supports RDNet control via EtherCON ports. This integration gives system technicians the flexibility to fine-tune the subwoofer’s performance in real time across complex PA setups using RCF’s intuitive RDNet GUI software.

Built for the Road with Practical Design Features
Constructed from rugged Baltic birch plywood and coated with a weather-resistant finish, the SUB 9006-AS is ready for the rigors of live events and transport. A heavy-duty steel grille protects the front-facing woofers, while strategically placed internal bracing minimizes cabinet resonance. Eight ergonomic side handles offer easier maneuvering for load-ins and setups. Designed with portability in mind, the enclosure can be stacked or integrated into flying configurations for larger venue applications.

Tuned to Deliver Tight and Defined Bass
Each of the two 18" drivers uses RCF’s inside-out voice coil design, maximizing surface area for heat dissipation and ensuring consistent performance even under heavy loads. This translates to tight, punchy bass with minimal distortion, even at higher volumes. For audio engineers, DJs, and live performers looking for controlled sub-bass performance without sacrificing headroom, the SUB 9006-AS provides the reliability and output required for professional-grade systems.

Versatile Connectivity and Configurable Output
With both balanced and unbalanced XLR input and link outputs, the SUB 9006-AS integrates easily into existing setups. Its extensive range of DSP presets supports a variety of performance environments and system types, whether used in a standalone setup or as part of a flown or ground-stacked array. The selectable EQ settings adapt the unit to different source materials, ensuring flexible use across genres and venues.
