DESCRIPTION

−

Optimal Audio delivers serious low-frequency reinforcement with the SUB18, a high-power 18" sub bass loudspeaker engineered for demanding commercial installations and entertainment venues. Designed to extend the bass response of any Optimal Audio system, the SUB18 provides deep, controlled low-end that fills rooms without sacrificing clarity or definition.

At the heart of the SUB18 is a long-excursion 18" driver capable of delivering substantial SPL with low distortion, ensuring tight and articulate bass reproduction even at high output levels. The robust enclosure is constructed from durable birch plywood with a hard-wearing finish, built to withstand the rigours of permanent installation in bars, nightclubs, live music venues, and multi-use entertainment spaces.

  • High-power 18" long-excursion bass driver for deep, impactful low-frequency output
  • Rugged birch plywood cabinet designed for long-term reliability in demanding environments
  • Optimised port tuning for extended bass response with minimal distortion
  • Seamless integration with the wider Optimal Audio loudspeaker and amplification ecosystem
  • Versatile deployment options suitable for floor-standing or concealed installation
  • Professional-grade connectors for secure, reliable signal connection

Whether paired with Cuboid series loudspeakers or integrated into larger distributed audio systems, the SUB18 provides the foundational low-end energy that elevates any professional installation from ordinary to exceptional.
