RCF has created a groundbreaking solution for offline/unpowered device configuration. With RDTap, users can inspect and configure devices without needing to power  the device. Sound engineers can design a system within the RDTap App on the move and configure each subwoofer by tapping the RDTap logo, with RCF [patent-pending] contactless technology. As an alternative, RDNet management software enables comprehensive real-time control and monitoring of compatible, network-connected devices.

INPUT – FEMALE XLR INPUTS (BALANCED)
The system is equipped with female XLR connectors for balanced audio signals. These inputs are designed to accept professional-grade audio sources, ensuring full compatibility with standard audio equipment.
Advanced Precision Transducers
SUB 9000 Series subwoofers incorporate the latest transducer technology from our labs. Employing lightweight aluminum core coils, high-damping cellulose cone material, composite spiders and a 4-layer inside-outside voice coil, the ultra-long excursion moving mass gains high power with fast acceleration. Despite their small and lightweight footprints, SUB 9000 Series subwoofers produce powerful yet articulate bass, remaining true to even the most subtle low-frequency variations.
High-Class Neodymium
Neodymium, a rare-earth material, enhances efficiency, power handling, and weight reduction. Using a 20% stronger magnetic field than typical neodymium grades, this new design enables precise control and higher force.

ADVANCED CROSSOVER ENGINE
FACTORY-TUNED PRESETS FOR PERFECT SUB-TOP PAIRING
Pair your full-range speaker with RCF ACE-enabled SUBs and unlock your system’s true potential.
RCF’s proprietary Advanced Crossover Engine (ACE) is engineered to precisely match the time delay and align the phase on a broader range than the usual crossover frequency range between RCF subwoofers and FiRPHASE-enabled full-range speakers. 
Breathe New Life Into Your Legacy Systems
When it’s time to upgrade, you don’t need to start over. Pair your HDL 20-A or HDL 6-A with our ACE-enabled RCF SUBs for a straightforward system update. You’ll benefit from factory-tuned presets and precise FiRPHASE filter tuning for enhanced sound performance; remote control via RDNet; simplified configuration with RDTap; system equalization; and delay alignment. And of course, all this is supported by the consistent low-end output of our latest RCF Precision Transducers.
