Networked, Stadium-Class Bass for Chicago DJs — RCF SUB 9006-AS
RCF SUB 9006-AS is a dual 18" active subwoofer built for modern touring rigs that demand clean, controllable low end. Two hyper-vented 18" neodymium woofers with 4.0" inside/outside voice coils are driven by a high-efficiency platform delivering 7200 W peak / 3600 W RMS for authoritative headroom. Variable low-pass up to 400 Hz and selectable high-pass points give system techs precise handoff control, while maximum output reaches 142 dB without losing punch.
The brain is a low-noise 32-bit DSP with presets, delay, polarity, and limiting, managed locally via the rear encoder or across large systems with RDNet. A Baltic birch cabinet, heavy-duty grille with foam backing, and Powercon IN/OUT make daily load-ins reliable. The enclosure footprint and hardware match RCF arrays, so you can stack with HDL 50-A 4K or HDL 10-A for scalable coverage from clubs to outdoor stages.
- Real-World Applications and Sound Roles:
- Ballrooms and large dance floors needing deep 30–60 Hz foundation with tight 70–90 Hz punch
- Club takeovers and festivals where networked control and fast preset recalls matter
- Corporate and install systems requiring extended crossover options up to 400 Hz
- Outdoor stages deploying cardioid groups to keep LF off mics and backline

- Built for Chicago DJs: Fast load-ins, networked recall, and punch that translates on packed dance floors.
Control Modes for RCF SUB 9006-AS
- Rear Encoder: Push to select function; rotate to adjust Gain reduction, Delay, or Preset. Two-digit display confirms values.
- Input Sensitivity: Nominal +4 dBu line level; gain reduction adjustable via encoder.
- High-Pass and Low-Pass: HP 30/40 Hz selection; LP variable 50–400 Hz to match tops.
- Presets (groups): INFRA S1 50 Hz LP, S2 60 Hz LP; EXTENDED LOW L2 60 Hz, L3 70 Hz, L4 80 Hz, L5 90 Hz (HP typically 30 Hz); CARDIOID SC/LC for forward and reversed boxes; LOW PASS EXCLUDED SE/LE with 20 Hz HP and LP moved to 400 Hz.
- Delay: Set in meters with fine steps, up to 20 m total range for arrival alignment.
- Phase/Polarity: Switchable for quick summation checks with adjacent subs or tops.
- RDNet: Onboard network control via etherCON for presets, EQ, delay, amplitude, polarity, monitoring, and grouping; local vs RDNet bypass switch.
- Protections and Indication: Thermal and RMS protection with fast limiter; LEDs for power, signal, preset, delay, and limiting states.
- I/O and Power: XLR in/link, XLR crossover out, RDNet IN/OUT etherCON, Powercon IN/OUT; convection/forced cooling.
Dual 18" Neo System With Hyper Ventilation
Each 18" cone uses a composite formula and a 4.0" inside/outside voice coil on a reinforced former. The hyper-vented architecture keeps power compression low so impact stays consistent through long sets.
32-bit DSP and Regulated Power
A low-noise 32-bit DSP manages EQ, presets, delay, and protection. The regulated supply maintains output from 100 V to 260 V, and the amplifier mounts on a Vibrostop floating aluminum panel for transport resilience.
RDNet Networked Control
Discover, group, monitor, and tune subs and tops from a central interface. Load presets, align timing, and adjust polarity across zones to keep LF focused where it matters.
Cabinet and Mechanics for the Road
Baltic birch plywood with a heavy-duty powder-coated grille and internal foam backing. Eight side handles support safe moves; dual M20 mounts expand stacking and pole options.
Array Matching With HDL 50-A 4K and HDL 10-A
Horizontal stacking aligns with HDL 50-A 4K; vertical stacking suits HDL 10-A. Two separate woofer chambers and an isolated amp bay support efficiency and reliability.
How to Deploy RCF SUB 9006-AS in the Field
Choose placement and presets to match room geometry, coverage goals, and tops. Use RDNet for fast group control or the rear encoder for stand-alone setups.
- Single or Dual: Center cluster for coherent coupling or L/R for wider rooms. Verify polarity and adjust delay for maximum summation at crossover.
- Preset Strategy: Use EXTENDED LOW (L2–L5) for typical DJ systems; choose INFRA S1/S2 when subs provide only the lowest octave beneath large arrays; select SE/LE when tops require a higher handoff up to 400 Hz.
- Cardioid Groups: Build 3-box gradients: two forward (SC/LC released) and one reversed (SC/LC engaged). Match gain, delay, and preset across the trio.
- Stacks With Arrays: Horizontal stack to fit HDL 50-A 4K; vertical stack for HDL 10-A. Maintain stable bases and use approved hardware.
- Alignment: Set delay in meters (fine steps up to 20 m). Sweep phase to confirm clean crossover transitions and even audience coverage.
- Power and Linking: Use locking Powercon IN/OUT within rated current. Keep AC and signal separated; use XLR link and crossover out as required.
Correct presets, polarity, and distance-based delay turn massive headroom into tight, musical low end that translates across the room.

Frequently Asked Questions — RCF SUB 9006-AS
What output and bandwidth does the SUB 9006-AS deliver?
Maximum output is 142 dB with a 30–400 Hz operating window using variable low-pass and selectable high-pass filters, powered by 7200 W peak / 3600 W RMS.
How do the onboard presets work?
Use the encoder to select groups: INFRA S1/S2, EXTENDED LOW L2–L5, CARDIOID SC/LC, or LOW PASS EXCLUDED SE/LE. Each sets HP/LP behavior for specific roles.
Can I control the sub over a network?
Yes. RDNet provides discovery, grouping, EQ, delay, polarity, monitoring, and preset recall via etherCON, with a local/RDNet bypass switch on the panel.
Is it a good fit for mobile DJs and club installs?
Yes. Dual 18" output, RDNet control, and touring mechanics make it ideal for Chicago-style quick turns and scalable installs.
How should I stack it with RCF arrays?
Stack horizontally to align with HDL 50-A 4K or vertically with HDL 10-A. Maintain stable bases and use approved accessories for secure geometry.
