All systems in the pro.CLASSICS range have been established in the market for many years and stand for long-lasting quality. pro.CLASSICS speaker systems are proven sound solutions for both mobile use and also in installations. Whether as a special installation version with no handles or feet, in ‘outdoor mobile’ and ‘outdoor installation’ version with 100-volt toroidal transformers, or in a variety of RAL colours on request, numerous options provide almost unlimited possibilities. K&F pro.CLASSICS - proven innovation.

The optimally tuned passive systems are distinguished acoustically through their use of all-pass filters. Furthermore, the K&F Line 212 an the K&F ACCESS series gives us two impressive high-performance systems. A true alternative is offered in the K&F SP series (self-powered), which is based on the same passive concept, but has integrated control and amplifier technology. The pro.CLASSICS products offer a large choice of solutions for all sound amplification situations. All in all - K&F pro.CLASSICS are the ideal sound systems for the widest variety of uses and provide maximum flexibility.



Powerful drive

With this high-quality self-powered loudspeaker system, the best possible sound characteristics and the ideally tuned amplification power are already integrated. This product series is based on selected models from the passive K&F CA and Line series, which are equipped with state-of-the-art, innovative driver and power amplifier technology. The implemented active electronics are run by the system-specific controller functions and include one to two highly efficient digital and fanless 1 kW class D power amplifiers. The complete electronic system weighs only 2.5 kg (or 4.5 kg). Remarkably powerful!

Completely compatible

All full-range systems from the SP series also have a passive crossover, in addition to the controller and power amplification electronics functions, which ideally complement the known advantages of the K&F passive technology (all-pass filters, safety switches). In this way, the full-range systems and subwoofers of the SP series are completely acoustically compatible with the corresponding passive models from the CA and Line series. Can be flexibly combined at any time!

Conceivably simple

All active speakers are ready to be used immediately, since the full-range systems of the SP Series reproduce the complete frequency range. If necessary, SP subwoofers can provide additional support to the bass playback. An optional high-pass filter on the SP subwoofer then determines the ideal crossover frequency. All systems in the SP Series can be combined with one another using the integrated phase alignment. Easy going!
