The Pinnacle systems are the perfect combination of slim and sleek column loudspeakers with compact and powerfull subfoofers. The Pinnacle-KR402 II is composed of a self powered Thunder-KS3 I subwoofer, driving both the couple of Python-KP102 I on its top and a separate passive column system made with Thunder-KS3P I subwoofer and two Python-KP102 I. The self powered Thunder-KS3 I subwoofer with DSP is designed to be the core device in the sound reinforcement system: the dedicated K-array Connect mobile app provides a user friendly interface for the remote control, the DSP parameters and to boost the system performance.
