Where to put your monitors in a small room

Speakers don’t get the last word in a small room; the room does. Two decent monitors set up with care will tell you more than an expensive pair shoved against a bookshelf. The good news is that placement costs nothing but an afternoon and a tape measure.

We will work through one real case the whole way: a spare room 3.1 m wide and 3.2 m long, about 10 m². Every number below for that room comes from our room planner, which applies the same rules. Make each decision in the order given, because each one fixes a number for the next.

1. Pick the wall you will face

Sit facing down the longer side of the room, with the speakers on a short wall. Peaks and dips in the bass get worse as you near the wall behind you, and this way that wall is as far off as the room allows (RealTraps). In our room the difference is only 10 cm, so the door or the window may decide it. In a 2.8 m by 4 m bedroom it matters a lot more.

Then find the line that splits the room into left and right halves, and put the desk on it. Both speakers should see the same side wall at the same distance, or the stereo image leans (Genelec). This is the real reason the desk never goes in a corner. The other reason is bass: a monitor in a corner gets a big lift in the low end (ADAM Audio).

2. Put the chair down before the speakers

Most people place the speakers and then sit wherever is left. Do it the other way round. Your ears sit in the room’s bass pattern, and some spots are much worse than others.

The worst seat is exactly halfway down the room. Every rectangular room has a deep bass dip at its halfway points (RealTraps), and Genelec also says to keep out of the exact middle (Genelec).

For where to start, the two best-known answers differ a little:

• 38% of the length from the front wall. That is acoustician Wes Lachot’s rule as RealTraps explains it, offered as a place to begin measuring, not a promise (RealTraps).
• Anywhere in the front third of the room, at least 1 m from every wall, for music work (Genelec).

They overlap more than they clash: 38% is just past the front third. In our 3.2 m room, 38% puts your head 1.22 m from the front wall, almost 2 m from the back wall and 1.55 m from each side. That clears Genelec’s 1 m everywhere, so we take it.

3. Size the triangle from the chair

The speakers and your head make an equilateral triangle, so the speakers sit 60° apart as you see them. On this point the sources agree: Genelec, ADAM and the EBU’s listening-room document all describe it the same way (Genelec, ADAM Audio, EBU Tech 3276).

How big? Two limits from ADAM are worth knowing. A pair can work as little as 1 m apart in a really small room. And to keep hearing mostly the speakers rather than the room, the spacing shouldn’t run past about a third of the room’s average length and width (ADAM Audio). In our room that ceiling is 1.05 m.

With the chair at 1.22 m and the speakers 0.35 m off the wall, the triangle comes out at 1.00 m a side. That fits between the floor and the ceiling of ADAM’s range, so nothing moves.

Ignore the 2 to 4 m speaker spacing you may see quoted from broadcast standards. The EBU figure is for reference listening rooms of 30 to 40 m² and more (EBU Tech 3276). It is the right answer to a different question.

In bigger rooms the ceiling starts to bite. Here is what the same rules give for our other example rooms:

When the triangle is held back, we keep the speakers near the wall and bring the chair forward rather than pulling the speakers out into the room. Why becomes clear in the next step. Notice that in both larger rooms the chair lands right where Genelec puts it, in the front third.

4. Decide how far from the wall

Sound from the back of the cabinet bounces off the wall behind it and comes back to cancel some of the bass. The distance sets which frequencies suffer. There are two ways out, and the mistake is the space between them.

• Close to the wall. Genelec wants the front of the monitor less than 0.6 m from the wall, with at least 5 cm behind a rear port (Genelec). ADAM says under about 0.5 m, with 10 cm as a practical minimum for heat and cables (ADAM Audio).
• Well away from it. More than 1.5 m, in ADAM’s figures. Few small rooms have that to spare.

So in a small room, close is the answer. Our plans put the centre of each speaker 35 cm from the wall, which keeps a typical small monitor inside both makers’ limits.

Close placement adds bass, and the makers disagree on how much. Genelec gives the textbook figures, 6 dB for one wall and up to 12 dB in a corner (Genelec). ADAM reports a smaller real-world lift, between 0 and 4 dB for each nearby wall, with brick giving more than plasterboard (ADAM Audio). Either way the fix is the same: most monitors have a boundary or room switch on the back, so use it.

5. Set the height and the aim

The tweeters go at the height of your ears in your working chair, pointed at your head. The figure for that height varies. The EBU assumes about 1.2 m for a seated listener (EBU Tech 3276), while Genelec suggests 1.2 to 1.4 m (Genelec). Measure your own: sit down, look straight ahead, and have someone hold a tape to the floor.

If the speakers have to sit higher, tilt them down toward you. The EBU allows 10° of tilt and Genelec 15°.

Don’t stand them flat on the desk. The desk top is a hard surface right in the path, so it sends an early reflection straight at you; stands lift the speakers and break that path (Dynaudio).

6. When the room is too small for the rules

Look at the 5 m² row in the table again. A 2.1 × 2.4 m box room can’t give you 1 m from every wall and a 1 m triangle at the same time. That is just the geometry.

In a room like that, mix on good headphones and treat a small pair of monitors as a second opinion, played quietly. If you do buy speakers for it, buy small ones. Makers match their models to listening distance more than to floor area: Neumann pairs its smallest monitor with short desk distances and its 5.25-inch model with small to medium rooms at 1 to 2 m (Neumann).

7. Check it, then move in small steps

Every number here is a starting point. Play a track you know with a steady bass line and slide the chair forward and back, 5 cm at a time. Listen for the spot where the low notes come through at even level. RealTraps goes further and says the only way to be sure is to measure the low end (RealTraps). A measurement microphone with analysis software such as Room EQ Wizard, which GIK Acoustics points readers to, does that job.

Once the speakers are placed, the side-wall reflection points are where the first panels go. Our next guide, treating a small room on a budget, starts there.
