PSB CS805 In-Ceiling 8" Speakers 3-Pack

PSB CS805 8" In-Ceiling Speaker (Bundle of 3)

The PSB CS805 8" in-ceiling speaker bundle of 3 is designed for discreet architectural installations where consistent PSB voicing and wide, room-filling sound are important. 

Neutral PSB Sound for Music and Home Theatre

The CS805 belongs to PSB’s CustomSound architectural family and is positioned as the entry-level 8" in-ceiling model that maintains PSB’s tonal character. It is intended for both music and home theatre use, including height and surround channels where a neutral, wide-response presentation is desirable.

• Two-way in-ceiling design with PSB voicing for neutral, music-friendly sound
• Suitable for whole-home audio and immersive home theatre, including height channels
• Consistent tonal balance with other PSB architectural and conventional speakers

8" Woofer for Extended Low-Frequency Output

Each CS805 uses an 8" (203 mm) carbon-filled polypropylene woofer that is engineered to extend low-frequency output for an in-ceiling design. This therefore adds more bass weight and impact, which helps the speakers fill larger spaces in distributed audio and home theatre systems.

• 8" carbon-filled polypropylene cone woofer for extended low-frequency output
• Design emphasis on better bass extension from an in-ceiling location
• Helps provide more room-filling sound in living rooms, kitchens, and larger areas

Textile Dome Tweeter for Smooth High Frequencies

The CS805 incorporates a 1" (25 mm) treated textile dome tweeter with ferrofluid cooling. This tweeter construction is intended to deliver smooth, controlled high frequencies, while ferrofluid cooling improves reliability and helps maintain low distortion during operation.

• 1" treated textile dome tweeter with ferrofluid cooling
• Design focus on smooth, controlled high-frequency reproduction
• Cooling and damping that support reliability and low distortion

Architectural Design and Installation Features

The CS805 is an open-back, flush-mount in-ceiling speaker with hardware and trim elements that support practical installation and a discreet appearance. Heavy-duty dogleg mounting hardware is used so the speaker can be clamped securely into the ceiling, which reduces installer time and helps ensure a stable fit.

• Open-back, flush-mount in-ceiling design for architectural installations
• Heavy-duty dogleg mounting system for fast, secure ceiling attachment
• Designed for both DIY home projects and professional custom installs

Discreet, Paintable Magnetic Grilles

Each speaker includes magnetic, frameless grilles. The grilles are paintable so they can be finished to match the ceiling, which allows the speakers to blend into a variety of interior styles.

• Magnetic frameless grilles for a clean, low-profile appearance
• Paintable finish to match ceiling color and décor

Use Cases and System Integration

The PSB CS805 is intended for whole-home and multi-room audio, as well as home theatre installations. Because the CS805 shares PSB voicing with other PSB models, integrators and homeowners can design systems that mix PSB architectural speakers with conventional PSB speakers while maintaining a consistent tonal character.

• Whole-home and distributed audio systems
• Home theatre applications including left/right, surround, and height channels
• Commercial and light-contractor projects where a value 8" in-ceiling speaker is desired
• Systems that require matching tonal balance with other PSB speakers
