Speaker Positioning Guide — Stereo / 5.1 / 7.1 / Atmos
Free interactive speaker placement guide for home cinema systems. Switch between stereo, 5.1, 7.1 and 7.1.4 (Atmos with 4 height speakers) — each renders a top-down room diagram with correct Dolby/THX angles, listener position, screen orientation, and per-speaker labels. Includes precise angle/distance recommendations from each official standard.
Placement principles
Each L/R pair must be the same distance and angle from the listener. Even 10 cm asymmetry is audible.
Aim tweeters at seated ear height (typically 110–120 cm). Center can sit just below or above the screen — angled toward listener.
Use the "subwoofer crawl" — place sub at the listening position, walk around the room until you find the spot with smoothest bass, put the sub there.
Real ceiling speakers are best. Up-firing modules sitting on top of front L/R reflect off ceiling — works ok with low textured ceilings, poorly with high vaulted ceilings.
