Can you? Yes. Will it behave like a closed, rectangular room? No. And that is fine, as long as the layout is planned around what the room actually has.
Most Indian living rooms are not shoeboxes. One side opens into the dining area, a wall is mostly glass, there is a door exactly where the left surround wants to be, and the sofa sits in the middle because that is where the family decided it goes.
None of this rules out surround. It changes where the speakers go and what you should expect from the bass.
What surround speakers actually need
For a 5.1 layout, Dolby's guidance places the surround speakers to the side of the main seat and slightly behind, at roughly 90 to 110 degrees from the screen direction. For 7.1, the rear surrounds sit further back, around 135 to 150 degrees.
Notice what that guidance does not say. It does not say the speaker must be on a wall. It needs the right angle, roughly the right height, and a clear path to your ears.
That distinction solves most open plan problems.
When one side has no wall
If one side opens into a dining area or a passage, the usual answers are:
- Speaker stands, placed at the correct angle, even if the nearest wall is far away.
- In-ceiling surrounds, a little outside the seating and aimed toward the listeners.
- A divider or furniture that can carry a speaker, if it is solid enough not to rattle.
What I would avoid is mounting the surround on whatever wall exists, even if it is 4 metres away on one side and 1 metre away on the other. Calibration can correct level and timing. It cannot move the speaker. Software is clever, but it has not yet learned carpentry.
I would also avoid dipole or bipole surrounds as a fix for odd rooms. In an open space they spray sound in every direction, and much of it bounces off glass and stone before reaching you. A normal direct radiating speaker, placed properly, is far easier to control.
When the back wall is open
If the seating has nothing behind it, or a bookshelf rather than a wall, 5.1 is often a better answer than 7.1. Two well placed surrounds beat four badly placed ones.
If you do want rear surrounds, stands behind the sofa or ceiling speakers slightly behind the seat are the usual options. Ceiling speakers also stay out of the walkway, which the rest of the house will appreciate.
L-shaped rooms
In an L-shaped room, pick one leg of the L as the theatre and treat the other leg as a neighbouring space. Place the screen and seating so the main seats sit inside the theatre leg, with the opening to one side or behind.
If the screen faces into the open leg, the front speakers fire into a space that just keeps going. That does dialogue no favours.
The real cost of an open plan: bass
This is the part people underestimate. Bass does not stay in the living area. It fills the dining area, the passage and anything else open to it. A bigger connected volume means the subwoofer has more air to move for the same level at the seat.
In practice, that can mean a larger subwoofer than the room size alone suggests, or two subwoofers placed to smooth the response across the seats. Two subs are not only about more output. They are often about fewer seats with weak bass.
Also expect whoever is at the dining table to hear more of the film than they planned to.
Where calibration fits
Auto calibration, and measured calibration with a microphone, can set levels, distances and some correction. In an asymmetric room that matters a lot. But calibration refines a sound layout; it does not rescue a bad one. Design first, measurement second, correction third.
Calibration is a paid service, and in an open plan room it is usually worth doing.
So should you wait for a dedicated room?
Usually not. A well planned living room system with sensible expectations is a better use of money than a theatre that exists only on paper. Accept that the open plan will change the bass and the speaker positions, and plan for it instead of fighting it.
