Description
The Optimal Audio Sub 6 Compact 6-Inch Passive Subwoofer is a highly compact, installation-focused low frequency solution engineered to enhance bass performance in commercial audio systems where space is at a premium. Designed as part of the Optimal Audio ecosystem, it delivers controlled, musical low frequency reinforcement to complement smaller full range loudspeakers such as ceiling or surface mounted models.
Developed specifically for discreet integration, the Sub 6 provides increased low frequency impact without requiring large enclosures, making it particularly effective in modern hospitality, retail and commercial environments.
Ultra Compact Design with Impressive Low Frequency Output
The Sub 6 features a custom designed 6 inch low frequency driver combined with a large ported enclosure to maximise efficiency and bass extension. Despite its compact form factor, it delivers 250W AES power handling and peak sound pressure levels of up to 118dB, producing a surprisingly punchy and musical low frequency response.
With low frequency extension reaching down to approximately 37Hz at -10dB, the Sub 6 ensures that systems gain depth and warmth without overwhelming the overall sound balance.
This makes it ideal for:
Retail stores and commercial spaces
Bars, cafés and restaurants
Corporate environments and meeting rooms
Background music systems requiring subtle low-end enhancement
Designed for Discreet and Flexible Installation
A key strength of the Sub 6 is its installation versatility. The enclosure is compact enough to fit through standard ceiling tiles, allowing for concealed placement where aesthetics are critical.
Flexible mounting options include:
Wall mounting using dedicated brackets
Ceiling installation for hidden integration
Floor placement with repositionable rubber feet
Suspension via integrated M8 fixing points
Recessed cable channels further support clean, professional installations by enabling discreet cable routing throughout the system.
Optimised for Use with Optimal Audio Loudspeaker Systems
The Sub 6 has been specifically designed to integrate seamlessly with Optimal Audio loudspeakers such as the Cuboid and Up series, enhancing system performance without introducing unnecessary complexity.
As a passive subwoofer, it requires external amplification and DSP control to operate effectively, ensuring system designers retain full flexibility over tuning and crossover configuration.
This enables:
Precise system tuning via external DSP
Scalable multi-zone audio system design
Consistent performance across distributed audio setups
Compact Build with Professional Durability
Constructed from robust MDF with a durable textured finish, the Sub 6 is built for long term reliability in commercial environments. An impact resistant perforated steel grille protects the driver, ensuring durability in high traffic or public facing installations.
Available in black or white, it can be visually integrated into a wide range of interior designs.
Engineered for Space-Conscious Commercial Applications
The Optimal Audio Sub 6 is purpose built for environments where traditional subwoofer sizes are impractical. Its ultra compact footprint allows it to be deployed in tight or hidden spaces such as under seating, within ceilings or mounted discreetly on walls, without compromising system performance.
Typical applications include:
Hospitality venues requiring balanced background music
Retail environments needing enhanced audio presence
Corporate AV systems and meeting spaces
Multi-zone commercial audio installations
