Phase Technology CS-6R 6.5" Coaxial In-Ceiling Speaker

The Phase Technology CS-6R is a 6.5-inch coaxial in-ceiling speaker designed for home theater, whole-house audio, and distributed sound applications. Its coaxial driver design combines a 6.5-inch polypropylene woofer with a 0.75-inch variable-axis soft dome tweeter, providing balanced full-range audio from a single ceiling location.

The variable-axis tweeter can be aimed toward the listening area, allowing the CS-6R to maintain more consistent high-frequency performance when the speaker cannot be installed directly in front of the primary listening position.

The CS-6R uses a 6.5-inch polypropylene woofer with an NBR surround for smooth low- and mid-frequency reproduction. Phase Technology's Absolute Phase™ crossover network helps maintain consistent response between the woofer and tweeter, while built-in auto-reset overload protection helps protect the speaker during higher-output operation.

A thin, magnetic, paintable grille is included for a clean installation that can blend with the surrounding ceiling.

Adjustable Tweeter for Flexible Ceiling Placement

One of the key advantages of the CS-6R is its variable-axis tweeter. The tweeter can be directed toward the listening area to help optimize high-frequency response when the speaker must be installed away from the ideal listening axis.

This makes the CS-6R particularly useful in rooms where ceiling joists, lighting, furniture, or other construction limitations prevent perfect speaker placement.

Full-Range Coaxial Audio

The CS-6R combines its woofer and tweeter into a single coaxial speaker assembly, providing full-range audio from one ceiling cutout.

The 6.5-inch polypropylene woofer handles low and mid frequencies, while the 0.75-inch soft dome tweeter provides high-frequency detail. The result is a practical in-ceiling speaker solution for music, television, presentations, and distributed audio.

Clean, Low-Profile Installation

The CS-6R includes a thin magnetic grille designed to sit cleanly against the ceiling. Its white finish can be painted to better match the surrounding décor.

The speaker requires an 8.06-inch cutout and has a 2.87-inch mounting depth, making it suitable for many residential and commercial ceiling installations.

A pre-construction bracket is also available for installations where the speaker location needs to be planned before drywall or ceiling material is installed.

Typical Applications

The Phase Technology CS-6R is well suited for:

• Home theater systems
• Whole-house audio
• Multi-room music systems
• Distributed audio
• Living rooms and media rooms
• Bedrooms and kitchens
• Offices
• Commercial AV installations
• Background music systems

Why Choose the Phase Technology CS-6R?

The CS-6R is a strong choice when you want a compact in-ceiling speaker with coaxial full-range performance and an adjustable tweeter. Its 6.5-inch woofer, variable-axis tweeter, paintable magnetic grille, and relatively shallow mounting depth make it flexible for both new construction and finished-room installations.
