    The Optimal Audio OAPAK-16 is a high-capacity add-on speaker kit developed to extend existing Optimal Audio systems based on the ZONE series mixer-amplifiers. Designed for venues requiring greater sound coverage and increased audio presence, this kit provides a simple and scalable route to expanding background music performance using higher-output surface-mount loudspeakers. OAPAK-16 is powered by the Optimal Audio Smart Amp 10 (SAMP10) and features six CUBOID3-TX surface-mount loudspeakers, delivering enhanced coverage and discreet installation. The system is configured to operate exclusively as a 100V line system, making it well suited to distributed audio applications where speaker quantity, cable runs and future scalability are key considerations. The loudspeakers are avaibale in both black and hite making integration to any venue a simple task without having to worry about ruining aesthetics.  As with all add-on kits in the OAPAK range, OAPAK-16 is designed to integrate seamlessly with existing ZONE-based installations, adding dedicated amplification and loudspeaker coverage without impacting the core system. 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.

Audio expansion kits are designed to extend or upgrade existing sound systems by adding additional speakers, amplification, or coverage areas. Rather than replacing your current setup, these kits allow you to scale your system to suit changing requirements, whether that’s expanding into new rooms, increasing output, or improving overall coverage.

The AV Barn offers a range of audio expansion kits suitable for hospitality venues, retail spaces, education environments and commercial premises. Each kit includes commercial loudspeakers along with the essential components required to integrate seamlessly with an existing system, such as speaker cable and connection leads where required.

Expansion kits are commonly used to extend audio into new rooms, outdoor areas or additional zones while maintaining consistent sound quality across the entire venue. Many systems are designed to work with standard 100V line or low impedance installations, allowing installers to scale systems efficiently as business requirements grow.

These professionally matched kits provide a practical solution for expanding background music systems, paging systems or public address installations without the complexity of a full system redesign.

If you are unsure which expansion kit is compatible with your existing system, use our AV system design page to submit your requirements and our team will recommend a suitable solution.
