Frequently Asked Questions
Is the CMX CSK-613HT suitable for commercial background music and voice announcements?
Yes. The 2-way coaxial design (6.5″ woofer + 1″ silk dome tweeter) delivers wide 80Hz–20kHz frequency response and 103dB max SPL, making it ideal for high-fidelity background music and clear voice evacuation paging in retail, corporate, and hospitality spaces.
What power taps are available on the 100V line transformer?
The onboard 100V line transformer provides multi-tap selections of 30W, 15W, and 7.5W, allowing audio engineers to balance volume levels across different room sizes and ceiling heights on standard 100V/70V commercial audio lines.
What is the ceiling cutout diameter required for installation?
The CSK-613HT requires a standard ceiling cutout diameter of Ø205 mm. The overall speaker outer diameter is Ø235 mm with a mounting depth of 110 mm.
How does the magnetic frameless grille work?
The speaker features high-strength neodymium magnets embedded in the outer ABS rim. Once the speaker is clamped into the ceiling, the white metal grille snaps flush over the baffle with zero visible bezel or mounting screws.
Can the magnetic grille be painted to match ceiling colors?
Yes. The magnetic steel grille can be spray-painted with acoustically transparent paint to match custom interior ceiling aesthetics without impacting acoustic performance.
