Sound experience

Feels like · Like a premium cinema: precise sound everywhere, with deep, even bass at every seat.

Best for · Rooms about 15 ft deep or more, ceilings 8.5 ft+. Most speakers, so plan the architecture early.

Full immersive Atmos, with every channel engaged.

Drag any speaker to fine-tune.

Dispersion visibility40 %

Drag corners to reshape · tap a wall to add windows, doors, openings or a corner · double-tap a wall to add a corner · drag the copper seat.

A great living room does not need to be a reference cinema. These targets are a guide, not a requirement.

Everyday Surround

2 of 2 applicable checks in planning range

Wall setback 7.5 ft

In planning range · target >0.5 m (1.64 ft)

Main seat to nearest wall, glass or modeled bed-speaker baffle; open spans excluded. A little breathing room helps with nearby reflections.

Adjacent surround spacing 70° maximum gap

No level-specific target

Between neighboring surround speakers, excluding the front soundstage. This describes smoothness of movement, not whether your room sounds good.

Discrete channels 11 feeds

In planning range · target ≥5

Ear-level and overhead feeds; all subs excluded. Your selected layout meets this feed-count target.

Acoustic dampening No level-specific target

No level-specific early-reflection target

0–15 ms, 1–8 kHz. A rug is a useful start; curtains and well-placed absorption can help. Rug estimates cannot establish this score. Room decay also needs separate assessment, with no distinct decay-time limit for each level.

Professional acoustic measurement

Early reflection relative to direct sound (dB)

Use a professionally measured 0–15 ms, 1–8 kHz value, e.g. −10 dB. Leave blank if unknown. This is not a rug reduction percentage.

Partial planning score at the main seat, not an overall RP22 level or certification. Reference and adjacent seats, output, bass, noise isolation and all other applicable criteria need review. Higher levels may need a custom room design.

Bare floors can reflect dialogue and music. A rug between the screen and seating can soften these reflections. Illustrative estimate, not a measured room rating.

2 ft of doorway: keep speakers clear of door swings, and use solid-core doors to limit sound leaking out.
