Cuboid 5TX is a full range, two way, passive 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 5TX 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 5TX features a 5.25” low frequency driver and a 0.75” silk dome high frequency driver mated to a shallow wave guide for consistent HF distribution.
Each Cuboid 5TX can be run on a series of 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 5TX 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 5TX FAQs
The Cuboid 5TX is a 5-inch, 2-way passive loudspeaker with a built-in transformer, designed for high-quality background music and speech reproduction in distributed audio systems. Here are its highlights:
- High-performance sound: Delivers clear and rich audio with a maximum SPL (Sound Pressure Level) of 105dB (continuous) and 111dB (peak) within a compact 5-inch design.
- Built-in transformer: The integrated transformer allows connection to constant voltage systems (70V or 100V), commonly used in commercial applications. This eliminates the need for individual amplifiers at each speaker location.
- Wide sound dispersion: Offers a 130° horizontal and 120° vertical coverage angle, ensuring good sound distribution throughout the intended listening area.
- Mounting options: Allows for both portrait and landscape mounting for flexible installation based on your space and needs.
- Weatherproof option: An optional weatherproof terminal cover (sold separately) makes the Cuboid 5TX suitable for outdoor use with an IP54 rating for dust and water resistance.
The Cuboid 5TX offers several advantages over the Cuboid 5:
- Constant voltage compatibility: Ideal for distributed audio systems using 70V or 100V lines, simplifying installation and reducing equipment needs.
- Eliminates individual speaker amplifiers: Reduces overall system cost and simplifies wiring by powering speakers from a central amplifier.
Due to its compact size, transformer integration, and weatherproof option, the Cuboid 5TX is suitable for various applications, including:
- Background music and paging in commercial spaces: Restaurants, bars, retail stores, offices, waiting rooms, etc.
- Background music and announcements in public areas: Airports, train stations, shopping centres, educational facilities, etc.
- Outdoor applications with weatherproof option: Patios, verandas, pool areas (with appropriate cover).
Yes, while the Cuboid 5TX eliminates the need for a separate amplifier at each speaker location, you will still need:
- A power amplifier: Compatible with 70V or 100V distributed speaker systems with enough power to drive the Cuboid 5TX speakers effectively, like the Optimal Audio SmartAmp series.
- Speaker cables: To connect the Cuboid 5TX speakers to the amplifier.
