The "One Wall Too Many" Rule: Navigating Physical Obstacles with the SoundSend

Because the WiSA SoundSend is incredibly compact, its internal broadcasting antennas are smaller than those found in standard, boxy AV equipment. While it easily blankets a standard living room with perfect wireless theater sound, the materials used to build your house can drastically shorten that 3-meter safety and performance bubble.

If you are experiencing single-speaker audio dropouts—especially on your rear iO1 speakers or your Lithe Audio WiSA Subwoofer—it’s time to check the physical path of the signal.

The Signal Blockers to Watch For

• Metal and Glass Furniture: If your SoundSend is placed on a shelf inside a heavy steel media console or directly behind a thick sheet of tempered glass, the 5GHz signal will bounce around inside the cabinet rather than escaping toward your ceiling speakers.

• Behind-the-Wall Obstacles: If you have an iO1 speaker mounted on a wall, or Pro Series speakers in the ceiling, check what's between them and the TV. Large metal structural beams (RSJs), internal metal piping, or heavy mirror backings will act as physical shields that a compact transmitter like the SoundSend struggles to pierce.

How to Guarantee a Strong Connection

• Give it an Elevation Boost: Don’t bury the SoundSend at the very bottom of an enclosed cabinet. Place it on the top surface of your entertainment unit, or mount it slightly higher up behind the top edge of the TV panel so it has a clear, angled trajectory up toward your Lithe Audio ceiling speakers.

• The Test Phase: Before permanently hiding the SoundSend or finalizing your furniture layout, turn your system on and check the WiSA SoundSend App. Look at the signal strength layout. If a speaker shows a weak connection, slightly shift the physical position or angle of the SoundSend puck on your stand until the connection signal goes solid.
