The Pinnacle systems are the perfect combination of slim and sleek column loudspeakers with compact and powerfull subfoofers. The Pinnacle-KR102 II is composed of a self powered Thunder-KS1I subwoofer, driving both the Kobra-KK102 I on its top and a separate passive column system made with Thunder-KS1P I subwoofer and one Kobra-KK102 I. The self powered Thunder-KS1I 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.
