With the performer's needs always at the forefront of RCF's design policy, they're easily one of the best out there when it comes to sound-system design. The new premium quality Sub-Series range of active subwoofers has been meticulously crafted to offer musicians and live-sound professionals a more up to date alternative to the previous 4PRO series, giving them the perfect tool to amplify their performance, night after night.

Renewed features, improved sound clarity and definition in a lightweight system

Featuring high-powered transducers, a new generation of Digital Amplifiers and a solid mechanical aluminium structure, the excellent SUB 8003-AS MK II is perfect for the performers on-the-go, being solidly built and lightweight with an awesome amount of power at their disposal. They are also perfect for building your own subwoofer satellite systems for when there's the need of high output levels without taking up too much space.

Powerful Amplifier

The SUB8003-AS II comes complete with a powerful new generation 2200 Watt digital amplifier for high-output, low distortion and natural sounds. The solid mechanical alumimium structure benefits the SUB8003-AS II twofold: first it provides a solid frame, stabilising the amplifier during transportation; and secondly, the highly-conductive materal also assists in heat dissipation.

Innovative Input Board

The input board offers not only stereo XLR inputs and a stereo XLR link-crossover output, it also features a built-in DSP with pre-programmed settings allowing for perfect and easy adaptation to RCF's active two-way speakers.


The three main settings on the Encoder are as follows:

  • Input Sensitivity - this controls the overall signal level at the input to the power amp.
  • Xover Presets - offers up to 24 dB/octave low and high pass filters, witth two high pass choices and four low pass choices within eight preset combinations, and cardioid presets available for all 30 Hz high pass presets
  • Time Delay - the time delay option is determined using this setting, with the delay setting expressed in meters

Multiple X-Over Presets

With the rear encoder you can (should you wish) select two groups of low pass filter presets: a 30Hz high pass and a 40Hz high pass, allowing you to select the frequency needed for the speaker satellite specific model.

High-Powered Woofer

The SUB 8003-AS II is equipped with a high-powered RCF woofer with voice coils representing an unmatchable reference in power handling, and an ability to transfer all sound to the cone with great clarity and reliability. The SUB 8003-AS II also features a bass-reflex design for production of extremely high SPL and reduced distortion levels.
