Description

The Optimal Audio Cuboid 6 is a compact 2-way passive loudspeaker designed to deliver high-quality background music and clear speech reproduction in commercial audio systems. Featuring a larger driver format than smaller models in the range, it provides increased output, improved low-frequency performance, and enhanced overall coverage while maintaining a discreet and installation-friendly design.

Engineered for distributed audio applications, the Cuboid 6 is ideally suited to environments where consistent sound performance, scalability, and clean aesthetics are essential.

Compact Design with Increased Output

The Cuboid 6 is built around a 6.5-inch low-frequency driver and a 1-inch high-frequency driver, delivering a fuller and more powerful sound profile with greater low-end presence and improved projection.

This makes it particularly suitable for:

  • Background and light foreground music
  • Speech reinforcement in larger spaces
  • Commercial environments requiring higher output from compact speakers

8 Ohm Low Impedance Operation

Configured for 8 ohm operation, the Cuboid 6 is designed for use with standard low impedance amplifiers, making it ideal for:

  • Small to medium sized audio systems
  • High-quality stereo or zoned installations
  • Applications requiring greater control over system design

As a passive loudspeaker, it allows system designers to match amplification to specific project requirements.

Wide Dispersion for Even Coverage

The Cuboid 6 delivers wide dispersion, ensuring consistent sound coverage across listening areas.

This enables:

  • Fewer speakers required for effective coverage
  • Even audio levels throughout a space
  • Improved listener experience in distributed systems

Installation-Friendly and Discreet

Designed for seamless integration into commercial environments, the Cuboid 6 includes a wall mounting bracket and supports both portrait and landscape installation.

Its compact enclosure and clean design make it suitable for:

  • Bars and restaurants
  • Retail environments
  • Offices and reception areas
  • Hotels and leisure venues

Indoor and Outdoor Flexibility

With an optional weatherproof terminal cover, the Cuboid 6 can achieve an IP54 rating, allowing installation in sheltered outdoor environments such as terraces and covered walkways.

Designed for Scalable Commercial Audio Systems

The Cuboid 6 integrates seamlessly with Optimal Audio amplification and control solutions, enabling scalable and efficient system design. It can also be paired with subwoofers such as the Sub 10 to enhance low-frequency performance in more demanding applications.
