RCF has released the new ART 4 series of speakers which are equipped with a powerful DSP that manages crossover, EQ., soft limiter, compressor and dynamic bass boost functions.
Extended Frequency Response and Linear Frequency Response.
Extended Frequency Response slightly emphasizes the bass response for playback music and low volume applications.
Linear Frequency Response is for live music applications where even freqency dispersion across the entire spectrum is desired.
The use of neodymium magnets on all the transducers of the ART 4 Series speakers drastically reduce the weight of the final cabinet and deliver better performance. Woofers and Compression Drivers are precision built at RCF's factory in Reggio Emilia, Italy ensuring RCF's superior moulding, assembly technologies and wealth of professional knowledge are continued in the ART 4 series.
The look of the ART 4 Series mirrors the functionality and aggressive design of the ART 7 Series. The newly designed 400W digital amplifiers (300 W for the low frequencies and 100 for the compression driver) coupled with the unique RCF transducers technology, make the ART 4 Series a cutting edge product suitable for any portable sound reinforcement applications.
