Detailed Description Column 8
Column 8 arranges eight 2.2-inch full-range drivers in a slim ABS enclosure. Its wide 150° horizontal pattern covers the listening area, while the narrow 7° vertical pattern helps direct sound away from ceilings and other reflective surfaces. The format supports speech and music in commercial interiors.
An integrated transformer provides selectable taps for 70 V and 100 V systems, alongside an 8 Ω operating mode. Power handling is 120 W AES. Speech and Music presets provide the corresponding system voicings; the manufacturer recommends an 80 Hz high-pass filter at 24 dB per octave.
The cabinet is available in black and white, with wall-bracket and safety-strap fixing points. Fit the appropriate terminal cover where the specified IP54 protection is required. Choose the amplifier and Sub options listed in the technical table to suit the installation.
