We will begin with a few words about the position of the speakers in the listening room.
Room acoustic and speaker position in that very same room have a tremendous impact on the sound. To achieve high-quality and/or superior sound, the speakers should be moved from the walls. This primarily refers to the distance from the side walls and the general angle of the room. The speakers should also be moved from the rear wall to create a virtual stage in front of the listener, which is expressed in all three dimensions (width, depth and height of the sound stage). How many speakers will be moved away from the walls depends on the specific room, condition, speakers, etc. Make sure that the speakers are not spaced too much in relation to each other, or you will get a blurred and stretched sound image of a bad focus sound stage – a spacing of approximately 200-220 cm will in most cases be quite sufficient. Rotate the speakers toward the listener. It takes a lot of patience and experimentation to find the position where your speakers will give their maximum in this particular case.
Most of music lovers apply the theory developed by Joachim Gerhard, a former constructor in the Audio Physic firm. He says that speakers should be mounted on a wider wall. The wider wall should be divided into quarters, and the shorter wall is divided into half. The speakers are placed on a line dividing the shorter wall half, that is, the longer wall on the line between the first and second quarters and the line between the third and fourth quarters – this does not have to be so literally. Namely, set the boxes as described, play a record and move the left and right boxes on that line. In the moment when the center of the sound is distorted or too stretched you will know that you have to go back with the boxes. The chair in which the listener is sitting is in the middle of a long wall, and the head is practically leaning on the wall itself. If this is not clear, look at the above image. The question arises how will this position of the loudspeaker in the room impact to the bass area because we know that many loudspeakers will be thin on the bass by leaving the rear wall. Basically, the area will not be disturbed because the listener gets bass by reflecting on the wall behind his back.
If we have said that the speaker position in the room has a great impact on the overall sound of your hi-fi system, then we had to say that there is one more important factor than that. And that’s the hearing acoustics. The acoustic of the listening room is called the mother of good sound, because it is the most important factor in achieving good sound. Your listening room acoustic is the most influential and most important component in your hi-fi system. The hi-fi system of middle rank placed in a room with a good acoustic will sound better than the expensive system set in the bad room.
Bad listening room is the one with too much echo (bare walls, naked floors, windows without curtains, etc.) as well as those that is too damped (thick carpets, heavy furniture, thick curtains, walls wrapped in shelves, etc.). Ideally, you’d find somwehere in the middle. In the echoing room your hi-fi system will sound extremely open, irritating, your head will hurt you after listening to music in that room. In a too damped room expect vice versa: lack of detail, freshness in sound, speed, etc. If your room can not be ideal, then it is better to be more echoing than too damped – but this is just my personal attitude. In practice, it may happen that a slightly more echoing room will benefit from a hi-fi system that is (too) dark; Conversely, a somewhat duller room may occur in favor of a more open-minded hi-fi system.
And while the size and shape of the room can not be affected, it would be wrong to ignore the walls, ceilings and floors. Every object you have in the room behaves like an absorber or reflector. Concrete, glass and stone, as the materials from which your room is designed, have the most influential effect on the sound of your hi-fi system and create a great echo. The bare brick is a solid choice, the plaster brick something worse. Each of these materials at different frequencies has a different degree of absorption. Wood is an excellent absorbing material, so audiophiles having walls with wooden panels on it can be considered lucky. In addition, unlike other materials that give different degrees of absorption at different frequencies, wood has linear absorption at all frequencies.
But the highest degree of absorption has – the human body. By the time I was actively engaged in playing in one of the band’s then I remember our gigs on one island. We came to the afternoon tone test, there was nobody in the club – the sound on the rehearsal of was desperate: open, loud, impossible to listen. A few hours later, the club was full of people and the sound was great.
With simple and thoughtful room acoustic you can dramatically improve the sound of your hi-fi system. But as I said, you need to be thoughtful, clever and patient. Place the carpet between the loudspeakers and listening positions. But, for example, the excessively thick and/or excessively large carpet placed between the speakers and the listener can suppress the high-range area. Place the wall shelves on the side walls. It’s great to show, assuming the speakers are moving away from the rear wall and placing the thick plush curtains on the wall beneath the loudspeakers, which greatly diminishes the focus and three-dimensionality of the sound image. For all this, little love and patience are needed, and financial investments are minimal. Do not insert into new components (whether it’s a new cable or a speaker) if the material we are dealing with in this article has not led to the maximum, because without that any further investment in the hi-fi system components is useless.
This is the end of our ultimate speaker placement guide.
