Dual-18 Authority for Chicago Dance Floors: RCF SUB 8006-AS
The RCF SUB 8006-AS is a high-output, active dual 18 inch subwoofer engineered for venues and mobile systems that demand deep impact and fast transients. Two 18 inch woofers with 4.0 inch inside/outside voice coils are powered by a 2500 W RMS (5000 W peak) Class-D amplifier to deliver up to 141 dB max SPL across a 30 Hz - 120 Hz range.
A DSP-controlled input section accelerates setup with selectable presets, delay control, Deep/Punch voicing, a phase switch, and a crossover section designed for quick integration. Convection cooling and an SMPS power supply keep performance stable while minimizing weight.
The Baltic birch tour-grade cabinet is stackable, pole-mountable (M20), and includes integrated mechanics for multiple configurations with HDL 20-A, making it a reliable backbone for rental inventories, club installs, and large mobile DJ rigs.

Power Platform: Class-D Efficiency, Real-World Headroom
The amplifier module delivers 5000 W peak / 2500 W RMS with an SMPS supply for high efficiency and reduced weight. Convection cooling maintains consistent output without fan noise in theaters, houses of worship, or corporate ballrooms.
Transducers: Dual 18 inch, 4.0 inch Voice Coils
Two long-excursion 18 inch woofers use 4.0 inch inside/outside voice coils and advanced materials to sustain punch and depth during long sets and high-demand program material.
Cabinet & Mechanics: Baltic Birch, Ready to Stack
Baltic birch plywood with a textured black finish, steel grille with internal foam, M20 pole mount, and integrated mechanics for multi-cab setups with HDL 20-A. Four side handles support fast, safe handling.
Workflow Speed: DSP, Delay, and Voicing on Board
The DSP-controlled input section provides selectable presets, output delay, Deep/Punch voicing, a phase switch, and crossover management to streamline tuning and repeatable day-to-day deployment.
How to Deploy the RCF SUB 8006-AS in the Field
Start by mapping coverage and audience distance, then select voicing and crossover settings that suit your tops and program. For punchy club mixes, a Punch voicing with appropriate crossover to tops tightens kick and bass lines. For larger rooms or open-air events, use Deep voicing and align delay to mains for coherent low-frequency energy.
- Stacking / HDL 20-A: Use integrated mechanics to stack HDL 20-A safely; follow hardware procedures and locking accessories as specified.
- Cardioid Groups: Build 3-box groups with the cardioid configuration option to reduce rear spill; match delay, polarity, and sensitivity across the group.
- Delay Alignment: Set output delay in meters to time-align subs to mains; measure physical offsets and fine-tune by ear for maximum summation.
- Crossover Strategy: Use the crossover section to hand off cleanly to tops; verify summation with the phase switch if needed.
- Power & Cabling: Use Powercon IN/OUT for secure mains; separate AC from signal lines to minimize noise.
Align delay, choose the right voicing, and the SUB 8006-AS delivers fast, musical impact that keeps Chicago dance floors moving.
