Crest Audio CPL 4L+ Passive Column Array Loudspeaker

Compact, install‑friendly column array speaker — ideal for speech, music playback, or PA systems where space is limited.

The Crest Audio CPL 4L+ is a passive column‑array loudspeaker engineered for clear, balanced audio in tight or discreet spaces: perfect for public address, background music, or live‑sound reinforcement in venues such as houses of worship, restaurants, retail outlets, corporate facilities, or small clubs. Equipped with four 3″ full‑range Neodymium drivers (0.75″ voice coils) in a sealed 12 mm plywood enclosure, CPL 4L+ delivers smooth full‑range sound while maintaining a slender profile. The enclosure includes a heavy‑duty steel grille with acoustic‑foam backing and a textured polyurea finish — robust enough for permanent installations or portable rigs. Connectivity is available via dual 4‑pin twist‑lock connectors or a 4‑pin Euroblock (with 2+/2– loop‑through), and the unit includes 7 M8‑threaded suspension points for flexible mounting (top, bottom, sides, and rear).
