- Single Sound Bar Configuration: Connect the two speaker units by aligning the rotary connectors and twisting until they lock securely. This configuration is ideal for placement directly below a TV or monitor.
- Two Tower Speaker Configuration: Separate the two speaker units. Each unit can be placed vertically on its base, positioned on either side of a TV, monitor, or PC for a wider stereo soundstage.
