The Optimal Audio Sub 15 is a high performance 15 inch passive subwoofer engineered to deliver powerful, extended low frequency reinforcement in commercial audio systems. Designed as part of the Optimal Audio loudspeaker range, it provides increased impact and depth where smaller subwoofer solutions are not sufficient.
With its combination of compact enclosure design and high output capability, the Sub 15 is particularly suited to venues requiring strong bass performance without excessive footprint.
High Output 15 Inch Low Frequency Performance
The Sub 15 features a high performance 15 inch driver housed within a bass reflex enclosure, engineered to maximise efficiency and low frequency extension. It delivers powerful sub bass support down to approximately 40Hz, providing significant depth and impact across commercial audio systems.
With peak sound pressure levels reaching up to 135dB, the Sub 15 is capable of delivering substantial low frequency energy, making it suitable for larger spaces and higher output requirements.
This ensures:
Deep and impactful bass response
High output capability for larger venues
Consistent performance under demanding conditions
Compact Design with Enhanced Acoustic Efficiency
Despite its powerful performance, the Sub 15 maintains a relatively compact footprint, allowing it to be deployed in installation environments where space efficiency is important. The bass reflex cabinet design improves airflow and efficiency, ensuring strong output without unnecessary enclosure size.
This makes it particularly effective in:
Bars, clubs and hospitality venues
Corporate and event spaces
Retail and commercial environments
Education and multi-purpose venues
Designed for Flexible Installation
The Sub 15 is built with installation versatility in mind, allowing it to be used in both fixed and semi-permanent setups. It can be floor mounted or flown using integrated mounting points, supporting a wide range of system configurations.
This enables:
Ground stacking for traditional deployments
Suspended installation for space optimisation
Integration into distributed audio systems
Optimised for System Integration
As a passive subwoofer, the Sub 15 requires external amplification and DSP, giving system designers full control over crossover, EQ and system tuning. This ensures it can be tailored to a wide range of commercial audio environments.
Designed to work seamlessly within the Optimal Audio ecosystem, it pairs effectively with loudspeaker ranges such as Cuboid and Up, delivering a cohesive and scalable system solution.
This enables:
Scalable multi-zone system design
Precise tuning for different environments
Seamless integration with full range loudspeakers
Robust Construction for Commercial Environments
The enclosure is constructed from durable plywood and finished with a hard wearing textured coating, ensuring long term reliability in demanding environments. A perforated steel grille protects the driver, while integrated rubber feet provide stability during installation.
This ensures consistent performance in high traffic commercial settings.
Engineered for High Impact Commercial Audio Applications
The Sub 15 is purpose built for applications requiring more substantial low frequency reinforcement than compact subwoofer models. It is particularly effective in systems where increased output and depth are required to fill larger spaces.
Typical applications include:
Bars and nightclubs
Live music venues and event spaces
Retail and commercial environments
Corporate AV and hospitality systems
A High Output Subwoofer for Professional Installations
The Optimal Audio Sub 15 delivers a strong balance of compact design, high output capability and installation flexibility. Its ability to produce deep, powerful bass while maintaining a manageable enclosure size makes it a dependable solution for commercial audio systems requiring enhanced low frequency performance.
