Guided Room Designer

Tell us your room.
We'll design the sound.

Enter your dimensions and how you'll use the space. The tool returns a technically-correct starting point — THX certification class, a Dolby Atmos speaker layout, subwoofer count, seating distance and screen size — calculated from Dolby and THX placement standards. It shows no pricing.

Convention used here: the screen sits on the shorter wall, and the longer dimension is your seating depth — the orientation reference cinemas are built around.

Your space

All dimensions in feet.

Depth = screen-to-back distance (the long axis). Screen wall = the shorter wall the screen sits on.

Leave on Auto for a room-matched layout, or pick a target configuration.

♪Enter your room and press Generate to see your THX class, Atmos layout, true-scale speaker plan and acoustic notes.

Speaker angles follow Dolby Atmos placement guidance and THX reference geometry; certification classes follow THX room-size limits (Select ≤ 2,000 cu ft · Ultra ≤ 3,000 cu ft · Dominus ≤ 6,500 cu ft, up to 20 ft viewing). Every recommendation is a starting point — your final system is specified by an eCloud engineer after an on-site acoustic assessment.
