KRK Systems uses state of the art tools to design and test its products. Additional technical information can be found in the product datasheets at www.krksys.com (Support/Product Documentation). Passion for audio is intrinsic in our culture and pushing the levels of performance each time we develop a new product is what drives our team. Some of the most advanced software applications are used to model, analyze and predict the performance of every component or assembly used in our loudspeaker system. Highly complex virtual models of mechanical, electrical and acoustic performance are evaluated, adapted and optimized. Prototypes are assembled and analyzers are used to evaluate the performance of the drivers, identify linear and non-linear parameters as well as distortion and thermal anomalies. Acoustic measurement tools are used to perform time, energy, frequency and wavelet analysis to allow visibility into the entire performance characteristics of the systems.

The most important tool however, is our ears! All the science in the world won’t replace the value of human hearing as an integrated phase in the voicing process. A panel of accomplished producers, engineers and artists are part of every product we develop. Each panelist has undergone rigorous testing of their hearing so that subjective perception is closely tied to objective analysis. Their combined expertise in the technology of acoustics and the art of music is what makes KRK products exceptional. Model KRK10s KRK12s KRK12sHO Model ERGO
