Owners of the Sonos Arc and Sub who experienced a lower Sub level on their Arc and Sub for months can heave a sigh of relief as Sonos has fixed the issues with a new software update.
According to a Sonos employee, “The Trueplay issue has been fixed. Customers who experienced a lower Sub level after performing Trueplay after updating to 14.12 will need to update their systems and then perform a new Trueplay tuning in order to address these improvements in their system. Customers will hear a more powerful low end response, meaning any Sub level adjustments made after 14.12 should no longer be required.”
