World's highest sound quality level car speaker!
Why do not you try incorporating sounds close to sound sources into your life?

World's highest sound quality level APM-SP1 car speaker becomes 16cm cone type speaker.

Why do you choose 16 cm, although there are 17 cm speakers that are popular for cars, there are reasons for that.

There is a way of thinking that is the basis of sound.

Those who are designed as speakers, even among sound mania, the speaker starts at 16 cm and ends at 16 cm.

The APM - SP1 car - speaker listens to the sound, but the sound comes in comfortably to the ear.

It strengthens the sound at the frequency where the person wants to hear the most.

If it is a small speaker it will not produce a bass, if it is too big a medium or high range will not come out, 16 cm is the size that matched the most full range speaker.

In recent years, the sound quality improvement has improved the sound quality wonderfully as a newly developed tweeter (treble) amplifier (amplifier).

After that, I think that if you can improve the sound quality of the full range (middle sound) woofer - (bass) speaker, you will achieve amazing high sound quality. One answer will be APM - SP1 car speaker.

The APM-SP1 car speaker's beating starts moving like a person's heart beating and leaves breathable bass and reverberation. Together with the movement, middle and high tone, middle tone will clear and high sound quality will be realized.

Singing voice and delicate performances of delicate artists will be reproduced.

It is wrapped in high-quality sound that has never experienced.


What is APM SOUND?
People listen to their ears with their ears. I will catch the sound waves coming out of the speaker with the eardrum and tell the vibrations to the brain.
At this time, even if a good sound comes out, it stimulates the eardrum strangely if noise is contained in it.
That makes a difference from natural sounds. We must make it sound easy for people's ears.
By realizing a structure and material that sound does not stress the eardrum, natural sound has been realized.
Finally, Autopromessumoto original speaker is finished.
