Usage recommendations

Position the speakers at ear height and keep some space from walls to reduce bass buildup. Use HDMI (ARC) or optical when connecting to a TV for the best digital audio quality; use Bluetooth for convenient mobile streaming. Start with neutral DSP and small manual adjustments to bass and treble to find a balanced sound for your listening environment.
