汽车配件｜RCF SUB702-AS MK3 12" 1400 WATT ACTIVE SUBWOOFER

SUB 702-AS II Active Subwoofer
Housing a 12” woofer, the SUB 702-AS II is a very compact active sub enclosure featuring a 1400W powerful digital amplifier. It is the ideal complement to 8” or 10” speakers, creating small but powerful satellite systems with outstanding performance. Thanks to its compact size, it can easily be carried and is very quick and easy to start using the built-in digital stereo crossover (DSP) with adjustable crossover frequency to connect the satellite.

12" Woofer, bass reflex housing
Stereo crossover
Switchable crossover frequencies
Phase-reverse switch
Electronic equalization, soft limiter, and protection
Stereo XLR input, Stereo XLR signal output

Powerful Lows
RCF subwoofers are the first choice of many sound engineers, thanks to the very high SPL levels at very low frequencies, smaller dimensions compared to competitors, self-powered design, and impressive size/weight to SPL output ratio. Your crowd will be able to live an engaging immersive musical experience.
Cabinet & Mechanics
The RCF cabinets are made of birch plywood coated with a textured black finish. The subs are stackable and lightweight, for easy setup and teardown, thanks to the ergonomic handles. A pole receptacle allows the use of the box in various configurations. The powder-coated front grille integrates a special transparent-to-sound foam backing on the inside to further protect the transducers from dust.
Powerful Class D Amplifiers
RCF's Class-D power amplifier technology packs huge performance operating with high efficiency into a lightweight solution. RCF amplifiers deliver an ultra-fast attack, realistic transient response, and impressive audio performance. The amplifier features a solid machined aluminum structure which not only stabilizes the amplifier during transportation but also helps the fan-less heat dissipation. All the amplifiers present SMPS power supply section to produce maximum output and minimum weight.

 



Bass Motion Control
When searching for an 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 the woofer stability, with extended linearity and better sound integrity.





The BMC method works by creating a complete map of the dynamic behavior of the woofer, to generate a custom algorithm that only limits over-excursions. 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.

 



Tour-Ready Workhorse
The subwoofer is suitable for a wide range of live sound applications. The rugged all-plywood cabinet is easy to carry and stack, due to its lightweight. All are equipped with ergonomic handles with rubber grips for easy setup and teardown. The M20 threaded pole mount on the top allows the cabinet to support speakers with a pole mount. The heavy-duty polyurea coating, the powder-coated metal grille, and the rugged structure of the cabinet withstand long-term use and transportation. Separate housing for the amplifier guarantees component efficiency and reliability. An acoustically transparent sound foam backing on the inside of the grille ensures protection from dust and humidity. With its frontal vented ports, the subwoofer can also be used in recessed spaces.
