CBT 70J-1 + 70JE-1 System
JBL

Purpose-Designed Extension for CBT 70J-1 Line Array Column Speaker.
With stronger grille

CBT 70J-1 + 70JE-1 System는 저음대역의 보강을 위한 익스텐션 스피커로써, BeamWidth 기술이 적용되어 있는 스피커입니다. 본 스피커는 슬림형 디자인이 필요한 공간에 최적화된 스피커이며, 보이스에 대한 명료도를 한층 증대하였습니다.

• 확장된 패턴 컨트롤 (400Hz에서 ± 20°조절, 200Hz에서 대부분의 off-axis 캔슬레이션)
• 확장된 베이스 응답성 - 45 Hz.
• 특허 출원된 Constant Beamwidth Technology™ 로 고음역대까지 지속적인 지향성으로 커버리지를 벗어날 경우의 로빙현상 감쇄
• 수직패턴 범위를 45도(중간 거리용 커버리지)에서 25도(먼 거리용 커버리지)로 조절 가능
