AUDAC CALI660II/W diffusore da incasso coassiale a 2 vie 6,5" per soffitto, 40W RMS, 100V/70V, bianco

The AUDAC CALI660II/W stands apart from typical ceiling speakers by combining a 6.5-inch 2-way coaxial driver with a built-in multi-tap transformer for both low-impedance and 100V/70V line operation. This dual-mode capability eliminates the need to choose between sound quality and installation flexibility, making it a versatile choice for distributed audio systems in retail, offices, and hospitality venues. Its robust ABS housing and paintable steel grille ensure durability and seamless integration into any décor.

Highlights

• 2-way coaxial design with 6.5" woofer and 1" tweeter for clear, detailed sound
• Selectable 100V taps (24W, 12W, 6W, 3W) and 70V taps (12W, 6W, 3W, 1.5W) for distributed audio systems
• 40W RMS power handling at 8 ohms, with peak power up to 160W
• Wide frequency response from 65 Hz to 20 kHz (±3 dB) and sensitivity of 88 dB
• Clean white finish (RAL9010) with paintable steel grille to match any décor
• Compact cut-out diameter of 186 mm and mounting depth of 80 mm for easy installation

In daily use

The CALI660II/W excels in environments where consistent, intelligible audio is required across multiple zones. Its 180° dispersion at 1 kHz ensures even coverage, while the 80° dispersion at 4 kHz maintains clarity for speech and music. The transformer taps allow you to connect multiple speakers to a single 100V or 70V amplifier channel without complex impedance calculations, simplifying system design and expansion. The ABS housing is lightweight yet durable, and the steel grille can be painted to blend seamlessly with the ceiling.
