Recommendations

For best sound and lighting performance, position the Aura Studio 4 in a central location with at least 20–30 cm of clearance around the dome to allow 360-degree sound dispersion. Keep the firmware updated when updates are available from the manufacturer and avoid exposing the speaker to prolonged direct sunlight or extreme humidity. For richer bass response, place the speaker on a solid surface rather than a soft or heavily damped substrate.
