If I were to pick just one article to recommend, I would like to introduce you to sound imaging tuning starting now.

If you don’t fully understand the content, be sure to read it several times.

**Main Text**

Dear audio enthusiasts who love music, welcome to the Apollon Audio website.

I hope you take the first step toward achieving the ultimate sound in your musical life, and I offer you a new philosophy to serve as your starting point.

When enjoying music through an audio system, how can you recreate the sound as if you were sitting in the best seat at a live concert?

You must take the following actions:

Adjust the toe-in angle of your left and right speakers as follows:

The listening position you are at is determined by taking the distance between the left and right tweeters as 100%, then calculating 70% of that distance, and setting your listening spot at that point centered between the two speakers.

Measure the distance between the left and right speakers based on the tweeters.

For example, if the distance between the left and right tweeters is 3 meters,

then the listening point is located 2.1 meters from the midpoint between the two speakers.

(Note: Measure the distance based on the tweeters, and be careful not to let a steel tape measure touch the tweeters, as this could cause damage.)

After setting the listening point at the 70% mark, adjust the toe-in angle of the speakers.

(The purpose of adjusting the speaker angle is to harmonize the two speakers so that the positions and images of the instruments are clearly formed.)

What happens if you set the listening point at less than 70% of the distance between the speakers and then adjust the toe-in angle?

No matter how carefully you adjust the toe-in angle, the harmonious sound image disappears and is replaced by a competing sound image between the left and right speakers.

I do not dispute the interpretation of this competing sound as a high-resolution 3D sound.

However, arguments only increase mental fatigue and leave wounds on both sides.

Therefore, I avoid arguments with others, clarify that the only subject of debate is audio issues within the development room, and will now proceed to the main point.

Sound, in short, varies depending on the space and position where you enjoy music.

The best position and the “anus position” coexist in the same space.

There may be slight differences depending on the room’s structure, but the vertex of an equilateral triangle is the “anus point.”

Sound that passes through the anus point is already mixed from left and right and appears out of phase.

Room tuning that minimizes reflection and refraction is not optional but essential.

From today on, just remembering that there is a point called the “anus point” when listening to music will allow you to experience the ultimate music.

To avoid the foolish act of listening to music at the sound’s “excretion point,”

the purpose of choosing audio equipment must be to achieve the ultimate sound reproduction.

Only then will the key points be revealed and clear sound heard.

What is the first reason why excreted sound is not heard?

If the purpose of choosing audio equipment is not to achieve ultimate sound but to make a sales compensation,

unfortunately, it will neither be heard nor seen.

Please look at this with a positive perspective rather than prejudice and empathize.

From today, please set the sound imaging point at 70% of the distance between the left and right tweeters.

Forming the golden acoustic point and completing speaker tuning does not solve all problems.

There is a task that must be carried out.

Sound that passes through the listener’s heart is like discarded food.

No matter how delicious the food is, if discarded, it rots and smells bad.

The same applies to music.

The space behind the listening point at the 70% mark is very important.

Distance between the left and right speakers and the listening point, and the rear space:

It is essential to secure 40% of the space and install sound-absorbing panels.

If securing more than 40% of the rear space in the listening room is difficult, please strengthen sound absorption treatment.

Trust this explanation, form a hypothesis, and test it.

You will surely feel that the experience has evolved to feel as if you are having a private session with the performer.

An audio system is not just a machine.

The reason ultimate audio is necessary is that it serves as a medium that brings the performer directly into your space.

In other words, the pathway is Apollon Audio.
