RCF SUB 8005-AS: 7 Powerful Features | For Sale

RCF SUB 8005-AS powered 21-inch subwoofers are available from AV Gear Experts. These professional active subwoofers are designed to deliver deep, powerful and controlled low-frequency reproduction for concerts, festivals, touring productions, houses of worship, nightclubs, theaters and professional rental companies.

Each unit has been professionally inspected, cleaned and fully tested to confirm proper operation. The integrated amplifier, woofer, input connections and onboard controls have all been checked. These subwoofers are ready to be added to a professional sound reinforcement system.

The SUB 8005-AS combines a high-powered 21-inch transducer with integrated digital amplification and onboard DSP processing. Because amplification is built into the cabinet, no external power amplifier is required. This simplifies system setup, reduces the amount of rack equipment needed and helps create a more efficient touring or installed sound system.

Powerful 21-Inch Low-Frequency Performance

The RCF SUB 8005-AS uses a high-power, hypervented 21-inch woofer equipped with a 4.5-inch voice coil. Its large transducer is engineered to reproduce extended low frequencies with the impact required for live music and large professional events.

With a frequency response extending from approximately 27 Hz to 120 Hz, the subwoofer can reproduce both deep bass information and the powerful upper-bass impact needed for kick drums, electronic music and other demanding program material.

The system produces a maximum sound pressure level of up to 137 dB at one meter. This high output makes it suitable for applications where strong, consistent bass coverage is essential.

Integrated Digital Amplification

Every RCF SUB 8005-AS features an integrated digital amplifier rated at 1,250 watts RMS and 2,500 watts peak. The onboard amplifier is designed to work specifically with the installed 21-inch woofer, creating a complete powered system inside one touring-grade cabinet.

A powered configuration offers several practical advantages. Users do not have to select and transport separate amplifiers, calculate amplifier-to-speaker power matching or install additional loudspeaker cables between an amplifier rack and the subwoofer.

The system only requires AC power and a compatible audio signal. This makes setup faster and can reduce the amount of equipment required for mobile productions.

DSP Processing and Professional Controls

The onboard DSP-controlled input section provides useful configuration options for different venues and system designs. Operators can select between Deep and Punch settings, depending on the desired low-frequency character.

The rear control panel also provides phase selection, high-pass settings, cardioid configuration and adjustable time delay. These controls help technicians align the subwoofers with the main loudspeaker system and manage low-frequency coverage.

Cardioid configurations can be especially helpful in professional live sound applications. When multiple compatible subwoofers are arranged and configured correctly, unwanted bass energy behind the system can be reduced. Proper cardioid setup should always be completed by an experienced system technician.

Rugged Touring-Grade Construction

The RCF SUB 8005-AS is housed in a rugged Baltic birch plywood cabinet built for professional touring and rental applications. The enclosure is designed to withstand regular transportation, setup and use at demanding live events.

Integrated handles help technicians move and position the cabinet. Optional protective covers and wheel kits may also make transportation and storage easier. Please confirm which accessories are included with the specific units before purchasing.

Because this is a large professional 21-inch powered subwoofer, buyers should verify cabinet dimensions, weight, available transportation and electrical requirements before completing an order.

Compatible RCF Sound-System Configurations

The SUB 8005-AS can be used with several professional RCF loudspeaker systems. It is particularly suitable for configurations featuring RCF HDL 10-A or HDL 20-A line-array speakers.

It can also be used in systems involving compatible RCF NXL-series loudspeakers when the correct hardware and configuration are selected. All stacked or flown configurations must use manufacturer-approved rigging accessories and follow official RCF safety instructions.

The correct number of subwoofers will depend on the venue, audience size, music style, desired sound-pressure level and number of main loudspeakers. Professional system-design assistance is recommended for large touring or installed systems.

Ideal Applications

The RCF SUB 8005-AS is suitable for a wide selection of professional audio applications, including:

* Live concerts and music festivals
* Touring sound-reinforcement systems
* Churches and houses of worship
* Nightclubs and entertainment venues
* Corporate productions and special events
* Theaters and performing arts centers
* Professional AV rental inventories
* Mobile DJs and production companies
* Permanent venue installations

Its combination of deep bass extension, high sound-pressure capability, onboard DSP and built-in amplification makes it a practical choice for professionals who require powerful low-frequency performance.

These are used professional subwoofers in excellent working condition. Each unit has been tested to ensure there are no known operational issues.
