I have in my home TV setup the Sonos Arc, Sub Gen 3, and two Era 100 as surrounds. The front speaker sound is abysmal in the lower mid frequencies. I know now that there is unfortunately no way to extend the system using a Sonos product as an additional front speaker. I am now desperately looking for creative solutions.
One idea that came to me early was to use the HDMI eARC output on the TV for the Arc, and then hook up a separate analog speaker using the optical audio out. This almost worked, but audio was too much out of sync.
Another solution would be to get a receiver hooked up to the TV that could forward output HDMI to the Arc and analog to the front speaker simultaneously. I’m not sure though if that kills off the eARC functionality, or if this also leads to sync issues.
What are your thoughts on this? Anyone with an Arc that solved the front speaker midrange problem? Any ideas welcomed.
