[제품설명]
컨트롤 Contractor Series는 컴팩트하고 견고한 2-웨이, 3-웨이 시스템으로서
고강성 폴리스티렌 재질이 도포된 인클로우저를 사용하고 있습니다.
광대역을 위하여 설계되어 있으며, 실내 및 실외에서 모두 사용이 가능합니다.
설치가 매우 쉽고 페인팅이 가능한 것이 특징이며 우수한 조작성 등 어떠한 업무용 스피커보다도
뛰어난 성능을 가지고 있습니다.
JBL의‘Invisiball’ 마운팅 기술은 가히 혁명적으로 설치를 쉽게 해주는데,
전면 패널을 통해 표준 육각 렌치를 사용하여 쉽게 최적의 상태로 고정할 수 있습니다.
설치에 필요한 렌치는 제품에 포함되어 있습니다.
색상은 Black, White 칼라가 있습니다.
