High-Power RCF 18-Inch Subwoofer
The RCF SUB 8004-AS features a high-power 18-inch low-frequency transducer designed to move a substantial amount of air while maintaining controlled and accurate bass reproduction. The 18-inch woofer incorporates a 4-inch voice coil and a hypervented design for high-output professional operation.
With its powerful integrated amplification and professional cabinet construction, the RCF SUB 8004-AS is designed for applications where strong and reliable low-frequency performance is essential.
2500 W Peak Power and 1250 W RMS
The RCF SUB 8004-AS features an integrated digital amplifier rated at 2500 W peak power and 1250 W RMS. The amplifier is specifically designed to drive the subwoofer’s low-frequency transducer, providing a complete powered subwoofer solution without requiring a separate external amplifier.
The integrated amplification makes the RCF SUB 8004-AS practical for professional sound companies, touring systems, event production and installation applications.
136 dB Maximum SPL
The RCF SUB 8004-AS can produce a maximum sound pressure level of 136 dB at 1 metre. This high output capability makes it suitable for professional applications that require substantial low-frequency energy.
The combination of an 18-inch woofer, high-power amplification and DSP processing allows the SUB 8004-AS to provide powerful bass performance for live music, events, touring and professional sound reinforcement.
DSP-Controlled Processing
The RCF SUB 8004-AS includes DSP-controlled processing designed to provide flexible system configuration. The integrated controls include crossover, phase, Deep/Punch, output delay and cardioid functions.
These controls allow sound engineers to configure the subwoofer according to the requirements of the complete PA system. Output delay can assist with system alignment, while phase and crossover controls provide additional flexibility when integrating the subwoofer with full-range loudspeakers.
Deep and Punch Low-Frequency Modes
The RCF SUB 8004-AS includes Deep and Punch operating modes that provide additional flexibility when configuring the low-frequency response.
Depending on the application, the appropriate mode can be selected to achieve the desired balance between low-frequency extension and impact.
Cardioid Subwoofer Configuration
The RCF SUB 8004-AS provides cardioid functionality for professional system configurations where greater control over low-frequency coverage is required.
Cardioid subwoofer configurations can help control the direction of low-frequency energy and reduce unwanted bass radiation behind the subwoofer system when properly configured.
This makes the SUB 8004-AS suitable for professional touring, live events and stage applications where controlled low-frequency coverage is important.
Professional Connectivity
The RCF SUB 8004-AS provides professional XLR input and output connections and supports balanced and unbalanced input signals.
The subwoofer also features PowerCON IN and OUT connections for professional power distribution and system deployment.
The input sensitivity can be configured for -2 dBu or +4 dBu, allowing the subwoofer to integrate into a variety of professional audio signal chains.
Tour-Grade Baltic Birch Cabinet
The RCF SUB 8004-AS is housed in a rugged Baltic birch plywood enclosure designed for professional use.
The cabinet includes handles on both sides and provisions for four-wheel mounting on the rear panel. An M20 pole mount is also provided for compatible system configurations.
The front of the enclosure features a protective steel grille, while the cabinet is finished in black for a professional appearance.
RCF SUB 8004-AS Dimensions and Weight
The RCF SUB 8004-AS measures 700 mm in height, 558 mm in width and 700 mm in depth.
The total weight of the subwoofer is approximately 56 kg.
These dimensions and weight should be considered when planning transportation, storage, installation and deployment.
