Biamp Desono C-IC6 6.5-Inch Coaxial Ceiling Loudspeaker

 The Biamp Desono C-IC6 is a 6.5-inch two-way coaxial ceiling loudspeaker designed specifically for speech reinforcement and conferencing applications. With wide 130° conical coverage, a low-profile design, and compatibility with both traditional speaker wiring and category cable, the C-IC6 is well suited for conference rooms, meeting spaces, classrooms, and unified communications installations.

The C-IC6 combines a 6.5-inch treated-paper woofer with a bridge-mounted 1-inch soft dome tweeter. The tweeter is mechanically isolated from the low-frequency driver to help maintain consistent speech reproduction across the listening area.

Designed for integration with the Biamp Tesira AMP-450BP PoE+ amplifier, the C-IC6 can also be installed using conventional speaker wiring. This provides flexibility when upgrading an existing AV system or designing a new conferencing installation.

Important: The C-IC6 is priced individually but sold in pairs.

Designed for Conference Rooms and Speech-Focused Applications

The Desono C-IC6 is optimized for environments where speech intelligibility and consistent coverage are more important than high-output music reproduction.

Its 130° conical coverage helps distribute audio broadly throughout a conference or meeting space, while the coaxial driver arrangement keeps the high- and low-frequency sources aligned.

Typical applications include:

• Conference rooms
• Boardrooms
• Corporate meeting spaces
• Unified communications systems
• Government facilities
• Education and training rooms
• Microsoft Teams Rooms
• Zoom conferencing environments

Flexible Audio Connectivity

One of the key advantages of the C-IC6 is its ability to accommodate different installation methods.

The speaker supports:

• Category cable connectivity
• Traditional speaker wiring
• Two RJ-45 connectors
• 4-pole Euroblock connection
• Up to 16 AWG speaker wiring

This makes the C-IC6 practical for both new installations and upgrades where existing speaker cabling may already be in place.

Optimized for Biamp Tesira PoE+

The C-IC6 is specifically designed to integrate with the Tesira AMP-450BP PoE+ amplifier, allowing audio and power distribution to be handled through a network-based installation.

For projects using compatible Biamp Tesira systems, this can simplify the speaker installation by reducing traditional amplifier and speaker wiring requirements.

The C-IC6 can also be operated as a conventional 8-ohm passive loudspeaker with DSP, providing additional flexibility for system designers.

Low-Profile Ceiling Installation

The C-IC6 uses a blind-mount installation design, allowing the speaker to be installed from below the ceiling. Its magnetic grille can be removed easily for installation and can be painted to match the room.

The speaker has a total depth of approximately 5.9 inches, making it suitable for installations where ceiling space is limited.

Installation Features

• Blind-mount installation from below the ceiling
• Four mounting clamps
• Approximately 1.4-inch mounting grip range
• Magnetic, paintable grille
• Approximately 9.75-inch ceiling cutout
• Approximately 10.9-inch overall diameter

Wide 130° Coverage

The C-IC6 provides a 130° conical coverage pattern, helping deliver consistent sound throughout conference and meeting spaces.

Its 6.5-inch LF driver and 1-inch soft dome HF driver provide a frequency range of 60 Hz to 20 kHz (-10 dB), with approximately 87–88 dB sensitivity at 1W/1m.

For speech-focused conferencing systems, the combination of wide coverage and coaxial driver alignment makes it possible to distribute audio evenly without requiring excessive numbers of ceiling speakers.
