ADVANCED CROSSOVER ENGINE

FACTORY-TUNED PRESETS FOR PERFECT SUB-TOP PAIRING

Connect your speaker to the SUB.

Select the preset.

Confirm and you are ready to go.

As an industry first, RCF offers effortless alignment of subs and tops by quickly recalling dedicated presets. This approach reduces setup time while delivering precise, consistent performance in different venues and system configurations, making advanced calibration accessible to a broader range of users.

Sub-Top Synergy for Unmatched Low-End Power

ACE operates across a broader frequency range than the typical crossover range, allowing the speaker to extend its operation to the lowest frequency available, and gain all the advantages of FiRPHASE technology. ACE transforms a sub+top system into a factory-tuned 3-way system, ensuring increased bass impact, low distortion, and improving overall sound quality.

Sub-Top Pairing: Measurements before (Red line) and after alignment (Green line).

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.
