Description

The Optimal Audio Cuboid 6TX is a compact 2-way passive loudspeaker designed to deliver high-quality background music and clear speech reproduction in commercial audio systems. Featuring an integrated 70V/100V line transformer alongside low impedance operation, it provides a highly flexible solution for distributed audio installations across hospitality, retail, and corporate environments.

With its larger driver format and enhanced output capability, the Cuboid 6TX is ideal for applications requiring greater coverage and stronger low-frequency performance while maintaining a discreet installation profile.

Compact Design with Increased Output

The Cuboid 6TX 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 improved bass response and 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

100V Line and Low Impedance Flexibility

A key feature of the Cuboid 6TX is its integrated transformer, allowing operation on:

  • 70V or 100V line systems
  • 8 ohm low impedance systems

Selectable power taps via a rear rotary switch enable straightforward system configuration, making it ideal for:

  • Distributed multi-speaker systems
  • Zoned commercial audio installations
  • Flexible system design across different environments

Wide Dispersion for Even Coverage

The Cuboid 6TX delivers wide dispersion of approximately 130° horizontal by 120° vertical, ensuring consistent sound coverage across listening areas.

This enables:

  • Fewer speakers required for 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 6TX includes mounting hardware and supports both portrait and landscape installation.

Its compact enclosure and clean aesthetic make it suitable for:

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

Indoor and Outdoor Capability

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

Designed for Scalable Commercial Audio Systems

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