The illustration above shows a common use for the CR8S-XBT subwoofer and CR-XBT monitors. Perhaps a friend
created a playlist on their smartphone and wants to share it. With great hesitation, you finally oblige. Everyone
has that one friend with terrible taste in music. We know, it happens.
In this example, a smartphone is connected to the CR8S-XBT subwoofer via Bluetooth.
From here, the L/R outputs from the CR8S-XBT are connected to the inputs of a pair of CR-XBT monitors using
RCA connectors.
Now position the subwoofer and monitors where you would like them. Play audio through the computer, making
sure that the volume of the smartphone, subwoofer and monitors are above "0".
Last step: move the subwoofer and monitors around until the optimal sound has been achieved and adjust volume
to taste.
