ZR speakers seemed destined only for the contest in the top class. This is also done by Steven, the owner of an audio workshop AJM, who participated in the contest EMMA SQ-HIN in Solo, Central Java. Steven uses speakers from ZR Speaker Lab Saturn type, which participate in the unlimited class. As a result, the expertise of Steven outperform competitors that use other speakers, and get a champion in Unlimited class. Congratulations! HI
