JBL IVX‑577136 – Intellivox H‑90 MKII Column Loudspeaker

The JBL IVX‑577136 is part of the Intellivox ADC (Analogue Directivity Control) Mark II series — a high‑performance column loudspeaker array engineered for 70 V/100 V public address and voice alarm (PA/VA) systems. It is optimized to deliver clear, highly intelligible speech reinforcement in acoustically challenging environments such as railway platforms, long corridors, and large indoor spaces. The array’s controlled directivity and column design help reduce sound spill outside the intended coverage area while maintaining consistent coverage across distance.
