CEILING PRO 4-A
Discreet 4-inch full-range ceiling loudspeaker
The CEILING PRO 4-A is a discreet 4-inch full-range ceiling loudspeaker designed for background music and clear speech reinforcement.
With wide 130° conical coverage, selectable 70/100V power taps and an 8Ω low-impedance option, it adapts easily to a wide range of installation requirements.
Its lightweight ABS construction, 4-pin Euroblock terminal, ultra-low profile design and bezel-free magnetic grille allow it to blend seamlessly into ceilings, even where mounting depth is limited. This makes the CEILING PRO 4-A particularly well suited to restaurants, retail and commercial environments where reliable audio performance and a clean, unobtrusive appearance are essential.
