Designed specifically for small to midsized venues and ideal for portable applications, the white RCF SUB 15-AX is a professional 15" high-powered active subwoofer well suited for bands, DJs, clubs, touring companies, and rental houses.

The subwoofer's integrated Class-D amplifier delivers 2200W of peak power to the 15" driver, which offers a frequency range of 35 to 120 Hz, with a maximum SPL of 133 dB, making it great for highly demanding applications. The rear panel features a centralized speaker management system providing dual crossovers, 8-band EQs, routing, delays, cardioid configurations, and recallable crossover presets. The polyurea-coated all-wood cabinet features sealed powerCON True1 TOP IP-rated mains power connectors.

• 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 a beat they can hear and a 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.

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 sub's crossover preset selection, system EQ, delay adjustments, and crossover individual settings are quickly accessible. When two subwoofer models are paired, they can be set up for 2.2 operation. LiveRemote App is available for Android and iOS phones and tablets.

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 setup and teardown. 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 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.

Lightweight and powerful, RCF woofers are a reference in high performance. RCF Precision Transducer engineers have developed new specific magnet sizes and molds to optimize magnetic flux while maintaining a low weight. The magnetic circuit topology is capable of delivering the highest balanced level of performance in three specific areas: maintenance of a consistent, high-integrity magnetic flux gap, exceptionally low distortion and efficiently integrating the magnetic circuit in a minimum weight design. The T-pole design optimization generates the minimum amount of flux modulation in the magnetic assembly during typical voice-coil movement within the gap.

With 2200W of power, RCF's Class-D amplifier can manage extreme sound-pressure levels with an ultrafast 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 switched-mode power-supply section combining high efficiency with minimum weight.

• When searching for extended bass with enhanced performance, RCF engineers found a way to remove the high-pass filter, replacing it with a forward-thinking approach. Introducing BMC (Bass Motion Control), the newly advanced woofer excursion-management feature. The speaker equipped with BMC can handle the lowest audible frequencies without affecting woofer stability, with extended linearity and better sound integrity.
• The BMC method works by creating a complete map of the dynamics behavior of the woofer, to generate a custom algorithm that only limits overexcursions. This gives total freedom of signal reproduction to the transducer. When high-pass filters normally protect the woofer motion from becoming destructive but change the phase behavior, the new BMC algorithm breaks conventional rules.

Q: 1. Will this work with Contryman B3 or B6?

A: I use B3's and yes they will.

Q: 2. Can it be used on Genaray Radiance? According to the picture, its mount looks different

A: The Godox 15° Reflector for ML60 uses the Godox mount connector; it is not compatible for use with the Genaray Radiance Daylight LED Monolight which uses the Bowens S-mount connector, not the Godox mount connector.

Q: 3. Does the Rayo include the mounting hardware and the PAD as other Mola reflectors?

A: It includes the mounting hardware for the pad, but depending on the strobe light you use, you will still need to purchase a speedring.

Q: 4. Would this be fairly safe as a wall spreader with just a camera and maybe small light attached?

A: Yes, no problem.

Q: 5. I am currently using Setti with opal defusion. I am now considering adding White Rayo, how does it feel with opal defusion?

A: The Mola Rayo Reflector (16") BH #MORW160 will have a longer more directional throw of light.

Q: 6. Would this fit the AD300pro ? I have a Godox mount reflector with an opening that won't fit around the bulb.

A: Yes the Godox 15° Reflector for ML60 fits direct onto the AD300pro.

Q: 7. Does the Rayo come with the pad perforated diffuser?

A: Yes, the PAD - perforated aluminum diffuser is shipped with every Mola reflector.

Q: 8. How do these shotguns do outside in heat and humidity? I do a lot of nature recordings and am interested in their low self noise

A: The Rycote HC-15 Short Shotgun Microphone is not IP-rated for moisture resistance, and Rycote has not specified a maximum ambient temperature for optimal operation. As such, and until further information is made available, it should be protected from moisture and caution should be taken when using the microphone in high temperatures.

Q: 9. Is there diffusion material already attached?

A: No, this is part of the two diffusion panels that are part of your softbox. Make sure you are getting the appropriate grid size.

Q: 10. Has anyone tried one of these Garfield Hush Lavs with a Countryman B6?

A: no but it work great with MKE1 and MKE2
