JBL Professional Control 26-DT - 6.5″ Coaxial Ceiling Assembly for Standard 8″ Rear Speakers (2 Units)
The JBL Professional Control 26-DT is a compact ceiling speaker system designed to be mounted in standard 200mm (8″) backcans . It integrates a coaxial transducer (6.5″ woofer with butyl rubber surround and titanium-coated tweeter), a crossover network , and a 60W transformer for 70/100V distributed lines. Its design offers high fidelity , low distortion , and 90° conical coverage with tweeter diffraction loading, ideal for mid-to-high ceilings where projection and uniformity are required.
The 26-DT retains the standard 8″ mounting system (194 mm screw circle) to accommodate a wide variety of existing grilles and backcans, simplifying upgrades and expansions. With a frequency response of 95 Hz–18 kHz (±3 dB) , sensitivity of 89 dB (1 W/1 m) , and a maximum SPL of 106 dB at 1 m, it delivers clear, balanced sound for both vocals and background music in an extremely compact size. This item is a 2-pack .
