These sound systems are acoustic all-rounders. Passive and 'Self Powered' variants with integrated amplifier electronics. Durable, flexible and always reliable. Proven solutions for the highest requirements.



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!
