Cuboid 6TX is a full range, two way, passive 6.5” loudspeaker designed to give exceptional sound quality in a very small form factor, for distributed applications with high quality background music and speech reproduction.
With its attractive design and included mounting hardware, Cuboid 6TX can be fixed in either portrait or landscape orientation for simple and flexible installation. A weatherproof terminal cover is available for outdoor use, bringing the rating to IP54.
Cuboid 6TX features a 6.5” low frequency driver and a 1” silk dome high frequency driver mated to a shallow wave guide for consistent HF distribution.
Each Cuboid 6TX has an improved 60w transformer which enables the delivery of premium sound when installed on 70 or 100V taps or at low impedance. Tap selection is via a rotary switch on the rear of the cabinet.
For enhanced bass performance, Cuboid 6TX can be teamed with Sub 10, and a SmartAmp or powered Zone will provide amplification, optimal sound settings as well as limiters to protect the drivers when playing at louder sound levels.
When coupled with Zone and WebApp, system set up and end user control is straight forward, and can be further supplemented by ZonePad wall controllers.

Optimal Audio Cuboid 6TX FAQs
There are notable features and benefits of Cuboid 6TX:
- Powerful sound: Delivers a maximum SPL (Sound Pressure Level) of 107dB (continuous) and 113dB (peak) for effective sound projection in medium to large-sized applications.
- Wide sound coverage: Offers a 130° horizontal and 120° vertical coverage angle, ensuring good sound dispersion throughout the intended listening area.
- Weatherproof (optional): An optional weatherproof terminal cover (sold separately) allows the Cuboid 6TX to be used outdoors with an IP54 rating for dust and water resistance.
- 70V/100V line operation: The built-in transformer enables connection to constant voltage distributed speaker systems (70V or 100V) commonly used in commercial applications. This eliminates the need for individual amplifiers at each speaker.
- Discreet design: The Cuboid 6TX maintains a professional look with a steel grille and a choice of portrait or landscape mounting options.
The Cuboid 6TX is a passive speaker and requires a separate amplifier to function. Optimal Audio offers compatible amplifiers like the SmartAmp series designed to work seamlessly with their Cuboid speaker range. The amplifier should have a compatible impedance rating (typically 8 ohms) and sufficient power output to drive the Cuboid 6TX speakers effectively.
Due to its powerful sound output, wide coverage angle, and optional weatherproofing, the Cuboid 6TX is suitable for various applications such as:
- Warehouses and factories (background music)
- Large retail stores (in-store music and announcements)
- Auditoriums and conference halls (speech reinforcement and music)
- Transportation hubs (public announcements and background music in stations or terminals)
- Outdoor applications (patios, sports facilities) with appropriate weatherproofing measures.
The Cuboid 6TX boasts a key advantage over the Cuboid 6: the built-in transformer for 70V/100V line operation. This makes the Cuboid 6TX ideal for larger installations where constant voltage distributed speaker systems are commonly used. The Cuboid 6, without the transformer, requires a separate low impedance amplifier for each speaker.
