Loudspeaker Audac CHA660 60 W — passive column speaker, model CHA660, 60 W nominal power

The Audac CHA660 is a passive column loudspeaker with 60 W nominal power designed for clear speech and background music reproduction in public spaces, conference rooms and retail environments. Its slender column form factor provides focused vertical coverage and wide horizontal dispersion, enabling intelligible sound across listening areas while minimizing reflections. The CHA660 connects to compatible amplifiers and PA systems and is intended for fixed installation where discreet, space-saving loudspeaker solutions are required.

Advantages

The column design offers controlled vertical directivity that reduces ceiling and floor reflections, improving speech intelligibility in reverberant rooms. Rated for 60 W nominal power, the unit can be driven by standard commercial amplifiers to deliver consistent background music levels and clear spoken announcements. Its passive configuration means simple integration into existing PA or amplifier setups without onboard amplification, and the mounting-friendly enclosure supports permanent, unobtrusive installation in venues where visual impact must be limited.

Suitable for

• Public address and paging in halls, stations and airports
• Conference rooms and meeting spaces requiring clear speech reproduction
• Retail environments and showrooms for background music
• Places of worship and community centers with fixed installations

Key specifications

• Nominal power handling: 60 W
• Passive (requires external amplifier)
• Column form factor for focused vertical coverage and wide horizontal dispersion
• Slim, wall- or pole-mountable enclosure suitable for permanent installation

How to use

Connect the CHA660 to a compatible external amplifier or mixer using appropriate speaker cable, observing correct polarity and matching nominal power and impedance requirements of the amplifier channel. Position the column to aim its main horizontal dispersion toward the listening area and mount at a height that provides clear line-of-sight audio to listeners. For speech-focused applications, orient the column vertically to take advantage of the controlled vertical dispersion; for distributed background music, install multiple units at regular intervals to ensure even coverage.

Usage recommendations

Match amplifier output and speaker impedance to prevent overload; avoid placing the column close to highly reflective surfaces that can cause comb filtering. Use multiple CHA660 units for larger or irregularly shaped spaces to achieve uniform SPL and consistent speech intelligibility.
