The Optimal Audio Cuboid 12 is a high-output 2-way passive loudspeaker designed to deliver powerful full-range audio performance in demanding commercial and professional environments. As part of the larger Cuboid series, it offers increased low-frequency extension, greater output capability, and enhanced projection, making it ideal for medium to large spaces where coverage and impact are critical.

Engineered for both installation and live applications, the Cuboid 12 combines robust construction with refined acoustic performance, providing a reliable solution for venues requiring strong and consistent sound reinforcement.

High-Output Design with Extended Low-Frequency Performance

The Cuboid 12 is built around a 12-inch low-frequency driver paired with a high-frequency compression driver, delivering a full-bodied sound profile with deep bass response, strong midrange presence, and clear high-frequency detail.

This makes it particularly suitable for:

• Foreground and background music systems
• Bars, clubs and hospitality venues
• Larger commercial environments requiring increased output

Its larger driver format ensures improved low-end performance compared to smaller models in the range.

8 Ohm Low Impedance Operation

Configured for low impedance operation, the Cuboid 12 is designed to be used with professional amplification, allowing flexible system design across a wide range of applications.

This enables:

• Integration into high-performance installed systems
• Flexible amplifier pairing based on project requirements
• Scalable multi-speaker system design

Controlled Dispersion for Targeted Coverage

Like other larger Cuboid models, the Cuboid 12 features a high-frequency compression driver with a rotatable horn, allowing consistent coverage whether installed vertically or horizontally.

This ensures:

• Controlled sound distribution across defined areas
• Reduced reflections in challenging acoustic environments
• Improved clarity and intelligibility

The controlled dispersion pattern makes it well suited to focused coverage in larger spaces.

Installation-Friendly and Versatile

The Cuboid 12 is designed for flexible installation, supporting both portrait and landscape mounting with compatible brackets and rigging hardware.

Its durable wooden cabinet construction and professional finish make it suitable for:

• Bars and restaurants
• Retail and showroom environments
• Leisure and fitness venues
• Corporate and event spaces

The enclosure design balances performance with clean visual integration.

Designed for Short to Medium Throw Applications

As part of the Cuboid range, the Cuboid 12 is optimised for short to medium throw distances, delivering rich, detailed sound with strong projection and precision.

This makes it particularly effective in:

• Medium to large commercial venues
• Open-plan spaces
• Areas requiring impactful yet controlled audio

Scalable System Integration

The Cuboid 12 can be used as a standalone full-range loudspeaker or combined with subwoofers to create a more powerful system for higher-impact applications. It integrates seamlessly with Optimal Audio amplification and control platforms, enabling efficient system setup and optimisation.

A High-Performance Solution for Commercial Audio

The Optimal Audio Cuboid 12 delivers powerful output, extended low-frequency performance, and controlled coverage in a robust and installation-ready design. Its combination of scale, clarity, and flexibility makes it a strong choice for commercial audio systems requiring high performance and reliable operation.
