Loudspeaker Audac CELO2 wired 10 W, 1 driver, 8 Ω, 100–20,000 Hz, white

Audac CELO2 is a wired, single-driver ceiling loudspeaker designed for compact installations where discreet appearance and reliable full-range sound are required. The speaker delivers 10 W RMS (maximum 20 W), with an 8 Ω impedance, 83 dB sensitivity and a frequency response from 100 to 20,000 Hz. Its ultra-compact outer diameter of 118 mm and 95 mm mounting depth allow flush installation in ceilings with minimal visible footprint. The driver is a 2" aluminium-cone unit housed in a ported, closed-back enclosure to improve low-frequency response while maintaining clear mid and high frequencies. A slim white grill and magnetic attachment ensure a neat finish that integrates smoothly into interiors.

Advantages

The CELO2 combines compact dimensions with engineered acoustic design to provide stable, natural sound in small spaces. Its ported enclosure and aluminium cone driver deliver a balanced tonal response that enhances speech intelligibility and background music. Installation features such as the quick-fix mechanism, Gold-Con™ spring clamp connectors and neodymium-magnet grill enable fast, secure mounting and simple service access. An internal self-resetting protection network increases reliability under varying load conditions.

Suitable for

• Background music in retail spaces, offices and cafés
• Public address and paging in small rooms and corridors
• Small meeting rooms, classrooms and waiting areas
• Locations requiring unobtrusive, white-finished ceiling speakers

How to use

Install the CELO2 into a compatible ceiling cut-out with at least 118 mm diameter and minimum 95 mm depth. Secure the speaker using the quick-fix mechanism and tighten the two mounting screws provided. Connect the amplifier output to the speaker using the Gold-Con™ spring clamp connectors, observing correct polarity. For consistent coverage, position speakers evenly across the listening area and avoid placing the unit directly adjacent to large reflective surfaces that can affect tonal balance. After connection, gradually apply signal and check sound quality at low levels before increasing to normal operating volume.

Usage recommendations

Use the Audac CELO2 for low- to medium-level background audio and speech reinforcement in small rooms. Match amplifier output to the speaker’s 10 W RMS rating and 8 Ω impedance, and allow headroom below the 20 W maximum to prevent thermal protection from engaging. For improved low-frequency presence in larger spaces, consider adding additional speakers or complementary bass reinforcement where needed.
