JBL Professional CBT 70J-1 Constant Bandwidth Technology 2-Way Line Array Column Speaker with Asymmetrical Vertical Cove, White

Deliver clear, predictable sound where intelligibility matters most. The JBL Professional CBT 70J-1 line array column speaker is engineered for professional PA, security and surveillance installations that require consistent vertical coverage and reliable outdoor performance. Using Constant Bandwidth Technology with analog delay beam-forming and amplitude tapering, the CBT 70J-1 minimizes narrow beaming and out-of-coverage lobing so voice paging, monitoring and alarm messages remain intelligible from front to back.

With 350W RMS power handling, 98 dB sensitivity and a usable frequency range from 60 Hz to 20 kHz, this 2-way 5" speaker delivers full-range output for speech and music without excessive distortion. The 8-ohm design maximizes amplifier compatibility, while the UV- and weather-resistant ABS, aluminum and fiberglass housing stands up to outdoor environments. Mount wall- or freestand for transport hubs, stadium concourses, retail complexes, houses of worship or integrated security systems.
