Description

The Optimal Audio OAPAK-20 is a high-performance low-frequency extension kit designed to enhance existing Optimal Audio background music systems with greater bass impact and headroom. Intended for venues with higher ambient noise levels or larger spaces, this kit builds on the OAPAK-19 concept by upgrading to a more powerful subwoofer solution, whilst keeping a compact form factor.

OAPAK-20 combines the Optimal Audio SUB10 subwoofer with the Smart Amp 10 to deliver controlled, authoritative low-frequency reinforcement. Designed as an add-on rather than a standalone system, the kit integrates seamlessly with existing Optimal Audio ZONE or Smart Amp installations, adding depth and warmth without disrupting the core audio architecture for small to medium sized applications.

The SUB10 offers higher power handling than smaller subwoofer formats, making it suitable for larger hospitality venues and spaces where greater audio presence is required. Flexible installation is supported through the included wall-mount bracket, while rack ears allow neat amplifier integration in equipment racks or back-of-house locations.

To complete installation, only balanced twin-conductor audio cable (microphone cable) is required to feed audio to the Smart Amp 10. This is available by the metre in black, allowing precise specification for each project.
