Unlock Your System's True Potential

The key to optimizing your sound system is the precise adjustment of your subwoofer's time alignment. This not only elevates sound quality but also enhances bass response, giving your audience both the beat they can hear and the vibe they can feel.

With internal factory-tuned crossover presets for RCF speakers, your sound system is show-ready in a few easy steps. Simply connect your satellite speakers to the SUB AX, select the crossover preset from the user interface, and you are ready to go. FiRPHASE linear phase is extended to match the subwoofer phase down to the lowest frequencies.

A Live Experience that is Completely Mobile

With the RCF LiveRemote app, you can control up to 8 AX devices via Bluetooth® simultaneously from your smartphone or tablet. The app makes it easy to adjust internal parameters and save and recall presets. You can also use the app to control your entire sound system, with a fully featured 8-band EQ and advanced functions.

LiveRemote App

Whether you’re a musician, DJ, or pro sound engineer, the RCF LiveRemote App, the same app that is used with the ART 9 AX, is now available with the SUB AX models. On the subs, crossover preset selection, system EQ and delay adjustments and crossover individual settings are quickly accessible. When two subwoofer models are paired, they can be set up for 2.2 operation. Available for Android and iOS phones and tablets.

Gig-Ready Solution

RCF cabinets are made of high-quality multi-ply hardwood coated with a rugged black (or white) polyurea finish. Subs are stackable and lightweight, have ergonomic handles with rubber grips, and are designed for easy set-up and tear-down. The M20 threaded pole mount on the top of the cabinet supports RCF speakers of various sizes. The powder-coated front grille integrates a special transparent-to-sound foam backing on the inside to further protect transducers from dust. SUB AX Series subwoofers are built to last, with powerCON® TRUE1 TOP mains connectors, so you can be sure that they will stand up to the rigors of use and transport.

Les meilleurs subwoofers

Légers et puissants, les haut-parleurs grave RCF constituent une référence en termes de hautes performances. Les ingénieurs à l’origine des haut-parleurs RCF Precision ont développé de nouveaux moules et de nouvelles tailles d'aimants spécifiques, afin d’optimiser le flux magnétique tout en maintenant un poids réduit. La topologie du circuit magnétique allie performances élevées et équilibre parfait dans trois domaines spécifiques : flux magnétique cohérent et d’une grande intégrité dans l’entrefer, faible distorsion, conception intégrée efficace du circuit magnétique réduisant le poids. La conception optimisée de type T-pole réduit au maximum la modulation de flux dans l’assemblage magnétique lors du mouvement typique de la bobine mobile dans l’entrefer.

Drive the Rhythm of the Beat

With 2,200 Watts of power, our Class-D amplifier can manage extreme sound pressure levels with an ultra-fast attack, realistic transient response, and very low thermal loss. The stereo input circuit features a low distortion design with an advanced safety limiter, maintaining the true character of the input signal at all levels. RCF amplifiers are designed according to EN62368-1 for maximum safety and present a Switch Mode Power Supply section combining high efficiency with minimum weight.

Afin d’étendre la réponse dans les basses et d’améliorer les performances, les ingénieurs de RCF ont trouvé le moyen de supprimer le filtre passe-haut, en le remplaçant par une approche novatrice. Voici le BMC (Bass Motion Control), un nouveau traitement avancé de gestion de l'excursion du haut-parleur grave. L’enceinte équipée du traitement BMC peut gérer les plus basses fréquences audibles sans affecter la stabilité du haut-parleur grave, avec une linéarité étendue et un rendu plus fidèle.

L’approche du traitement BMC s’appuie sur la cartographie complète du comportement dynamique du haut-parleur grave, afin de générer un algorithme spécifique ne limitant que les excursions excessives. Il laisse donc une liberté totale de reproduction du signal au haut-parleur. Les filtres coupe-bas normalement utilisés réduisent le débattement susceptible d’endommager le haut-parleur grave, mais ils modifient aussi la réponse en phase. Le nouveau traitement BMC permet de s’affranchir de cette règle.
