RCF SUB 8008-AS Dual 18 Powered Subwoofer for Touring DJs

RCF SUB 8008-AS Dual 18-Inch Powerhouse for Serious Low End

The RCF SUB 8008-AS is a professional, high-output powered dual 18-inch subwoofer engineered for live bands, DJs, clubs, and touring rental companies that need real low-frequency authority. With 4400W Class-D bi-amplification, a linear 30–120 Hz response, and sound pressure levels up to 137 dB, it delivers deep, controlled bass that keeps large rooms moving without losing definition.

At the heart of the cabinet are two 18-inch high-power woofers built around a 4.0-inch voice coil and advanced ceramic magnet topology to maintain strong, consistent flux in the gap. The result is high output with exceptionally low distortion, even when the system is driven hard during peak moments of a show. RCF’s amplifier platform is so efficient that it operates with silent, fan-less cooling, using a solid aluminum heat exchanger instead of moving parts.

On the rear panel, you get a full set of DSP tools: 8 crossover presets and 4 cardioid presets, Deep or Punch voicing, selectable crossover frequencies, polarity control, output delay, and safety limiters. IP-rated Powercon TRUE1 TOP IN/OUT power connectors support professional touring practice. A rugged, all-plywood cabinet with scratch-resistant polyurea coating, steel grille with acoustic foam, and dual M20 pole mounts makes the SUB 8008-AS equally at home in vertical or horizontal deployments.

Built as a tour-ready workhorse, this sub integrates naturally with RCF full-range systems—whether you are flying HDL 6-A line arrays, running NX 915-A or NX 985-A tops, or pairing with ART 945-A cabinets. For Chicago DJs, clubs, and production houses, it provides the kind of headroom and reliability you want in mid to big-sized venues and outdoor events.

Real-world applications and sound roles:

• High-output subwoofer foundation for touring live bands and production companies.
• Club and large bar systems where deep, punchy dance-floor bass is mandatory.
• Chicago mobile DJ rigs needing scalable dual 18-inch sub arrays for weddings and festivals.
• Cardioid ground stacks for tighter low-frequency control on stage and in reflective rooms.
• Rental inventory workhorse that pairs with RCF line arrays and point-source tops for flexible packages.

• Vertical or Horizontal Mounting: Two M20 pole mounts on the top and side support both vertical and horizontal configurations with compatible RCF tops.
• Chicago DJ and Rental Friendly: Compact footprint for a dual 18 makes truck space efficient while still delivering the output big city shows demand.

Control Modes for the RCF SUB 8008-AS

The rear panel DSP of the SUB 8008-AS is designed to give system techs and DJs fast, predictable control without needing an external processor. A bank of presets, filters, and timing tools helps you lock in low-frequency performance for a wide range of rigs and stage layouts.

• 12 Total Presets: Factory voicings optimized for typical RCF top combinations and deployment styles.
• 8 Crossover Presets: Selectable crossover points tailor the handoff between the SUB 8008-AS and full-range cabinets for smooth system response.
• 4 Cardioid Presets: Built-in cardioid options make it easier to configure multi-sub arrays that reduce stage and backstage LF buildup.
• Deep / Punch Selection: Choose Deep for extended low-end weight or Punch for tighter, more aggressive attack depending on music style and venue.
• Phase and Polarity Control: A phase switch lets you correct alignment with flown arrays or nearby subs without external processing.
• Output Delay Setting: Onboard delay aligns subwoofer arrival time with flown or pole-mounted tops and can help time-align distributed systems.
• Comprehensive Protections: Thermal, excursion, and RMS limiters, along with a soft limiter circuit, protect the transducers while maintaining the character of the input signal.

Combined with balanced XLR in/out and IP-rated Powercon TRUE1 TOP power connectors, these controls let you walk into a club, ballroom, or festival stage and quickly tune the sub section to the room.

Deep Bass Engineering, Smart Power, and Touring-Grade Design

Dual 18-Inch Transducers Built for Extreme SPL

RCF’s dual 18-inch woofers in the SUB 8008-AS use a 4.0-inch voice coil and a carefully optimized ceramic magnet circuit to maintain a strong, stable magnetic field across the gap. That engineering focus delivers high linear excursion, tight cone control, and very low distortion at the kind of SPL levels modern dance music and rock shows demand.

The magnet and T-pole design minimize flux modulation during heavy voice coil movement, so the sub stays clean and musical instead of smearing low frequencies when the system is pushed. For DJs and engineers, that translates into bass that feels big and impactful while still integrating smoothly with your tops.

4400W Class-D Amplifier with Fan-Less Reliability

The 2-channel Class-D amplifier in the SUB 8008-AS delivers up to 4400W peak power, combining high efficiency with a fast, realistic transient response. The stereo input section and crossover are designed for low distortion, and an advanced safety limiter maintains the true character of the input signal even at maximum level.

Because the amplifier is highly efficient, it is cooled by a solid aluminum heat exchanger rather than a fan. That means quieter operation, fewer moving parts to service, and consistent performance in hot rooms, outdoor festivals, and tight club installs. Compliance with EN62368-1 safety standards further supports professional touring and integration work.

Flexible System Building with RCF Tops and Line Arrays

The SUB 8008-AS slots naturally into a wide variety of RCF-based systems. It can anchor a vertical stack with HDL 6-A line arrays, sit at the center of a stereo rig with NX 915-A tops, or run in horizontal orientation with NX 985-A or ART 945-A cabinets. Cardioid ground stacks using three SUB 8008-AS units help control bass on stage while keeping the audience area energized.

This flexibility makes the cabinet especially attractive for rental companies and Chicago event providers who need to cover clubs one night, corporate ballrooms the next, and outdoor stages on the weekend—all while standardizing on a single dual 18-inch platform.

Tour-Ready Cabinetry for Demanding Schedules

The all-plywood cabinet is finished in a heavy-duty polyurea coating and defended by a powder-coated steel grille backed with acoustically transparent foam. This combination resists dings, dust, and humidity during transport and long-term installs. A dedicated housing for the amplifier helps thermal performance and protects electronics from impact and debris.

Ergonomic side handles with rubber grips make the 80 kg cabinet easier to manage with a crew, and two M20 threaded pole mounts on the top and side let you choose vertical or horizontal setups. Front-facing vented ports allow the sub to operate reliably even when pushed against walls or recessed into stages, keeping low-frequency performance consistent across different venues.

How to Deploy the RCF SUB 8008-AS in the Field

The SUB 8008-AS is built to drop into real-world rigs quickly, whether you are flying RCF arrays or running ground stacks for DJ and live sound work. A little planning around placement, presets, and cardioid options goes a long way toward getting clean, powerful bass.

• Choose your configuration: Decide if the sub will run as a single unit, in stacked pairs, or in a multi-cabinet cardioid array for tighter stage control.
• Place cabinets on solid ground: Use stable, level surfaces and keep the front vents clear, especially when the subs are recessed under stages or into platforms.
• Select the right crossover preset: Match the built-in crossover presets to your RCF tops—whether HDL 6-A, NX 915-A, NX 985-A, or ART 945-A—to ensure a smooth handoff between sub and mains.
• Set Deep or Punch mode: Use Deep for extended low-frequency weight in EDM, hip-hop, and organ-heavy material, or Punch for tight, fast bass in rock, pop, and speech-heavy events.
• Leverage cardioid presets: For multi-sub arrays, choose one of the cardioid presets and follow RCF’s recommended spacing and orientation to reduce rearward bass energy.
• Time-align with tops: Use the output delay to align sub arrival time with flown or pole-mounted tops, especially in larger rooms or when subs are set forward of the mains.
• Confirm limiter and gain staging: Feed a clean, appropriate level from your system processor or mixer to let the onboard soft limiter work transparently.

With these steps dialed in, the SUB 8008-AS becomes a reliable foundation for Chicago ballrooms, clubs, houses of worship, and outdoor stages where consistent, musical low end is a must.

Deploy the RCF SUB 8008-AS as the low-frequency anchor of your system and you will feel the difference in every kick drum, drop, and bass line across your busiest weekends.
