If I add the Polycom Stereo Speaker Kit to my VSX 7000, do I use both subwoofers?
Yes. The VSX 7000s systems subwoofer provides both power and H.320 connectivity to the system and is required. The subwoofer in the Stereo Speaker Kit will provide the base for the video calls. Simply turn off the internal audio (speakers and subwoofer) on the VSX 7000s base unit when using the Stereo Speaker Kit.
