System Configurations
The versatile Bose® S1 Pro system operates in four unique modes. With Auto EQ, the system automatically
updates to maintain optimum tonal balance for each position. Use the examples below to quickly identify the
best mode for your application.

Elevated Surface
Position the S1 Pro on a surface. This projects sound clearly and evenly throughout the audience, and ensures that audience members enjoy the full frequency range of the system.

For performances where your audience is close to you, tilt the S1 Pro onto its back edge. For best results, the performer should stand or sit to one side of the loudspeaker to avoid blocking sound from the audience.


To use the S1 Pro as a personal floor monitor, place it on the ground horizontally, in front of and pointing toward the
performer. Tilt the loudspeaker onto its side edge.


Speaker Stand
Place one or two S1 Pro systems on speaker stands (sold separately) for general-purpose sound reinforcement.
