Add more voice coverage to your VC520 PRO deployment without changing the core conferencing setup. The AVer COMEXPSPK expansion speakerphone is designed to complement the VC520 PRO system in rooms where a single audio point is not enough. It gives IT teams a straightforward way to improve speech pickup across larger tables, longer huddle rooms, and shared conference spaces where participants sit farther from the main unit. For organizations standardizing on AVer video conferencing, this expansion speakerphone helps preserve audio consistency as room size and seating density increase. It is a practical add-on for teams that need clearer participation from every seat, especially in meetings where remote attendees depend on accurate voice capture. The result is less repetition, fewer missed comments, and a more usable conference experience for everyone on the call. Because it is purpose-built for the VC520 PRO ecosystem, the speakerphone fits naturally into existing deployments and procurement plans. It is the kind of accessory that makes sense when audio quality matters enough to justify a more complete room design, but not enough to replace the entire system. For enterprise environments, that balance is often the difference between a functional room and one people trust for daily use.
