Can I add the sub mini to my existing system for extra bass? I have an Arc Ultra, Sub 4, two Era 300’s. Thanks

Not if they’re configured as a home theatre system. 
Yes if the Eras are individual or a stereo pair.

    Thank you for the information! That is what I needed to know. Bummer that is not an option.

    You can add another Sub though.

      The Arc Ultra already has more base than the Arc. Sonos probably thinks a Sub mini does not ad much extra.
