What is an attenuator?
An attenuator (ATT) is a resistance attenuator. It is like a kind of volume, and by turning the knob to the right or left, the sound level (strength) changes to +/-. It can be continuously variable or stepped with a decibel scale.
The role of speakers
The speaker product page is here
The speaker's attenuators are used to fill in the level difference between the units such as the woofer, scooker, and tweeter, and flatten the characteristics.
Speakers are usually woofers, while scooters and tweeters are designed to be more efficient, so an attenuator is installed to adjust the level of scooters and tweeters. The levels between units can be adjusted to your preferred level, depending on the condition of the room where the audio is installed and the music genre you are watching.
It seems that the types of speakers that are used in recent years are limited, so I don't see them very often. As with the manufacturers we handle, the sound tuning is made with high precision inside the speakers along with the network circuit, making it unnecessary.

Another method of using attenuators is adopted as a volume circuit in amplifiers, or in devices that are particularly particular about sound quality and volume control functions, such as "passive attenuators," which have removed the amplifier circuit from the amplifier.
The amplifiers generally have a volume adjustment function, so you might think that the volume will change at a very high level, but the attenuator is a great item that changes the sound dramatically just by changing this.

By using an attenuator in the volume section of the amplifier, it is possible to reproduce sound with higher definition and precision than the volume circuits normally used, providing a wide and expressive music. The accuracy of the reproduced sound also changes depending on the accuracy of the resistor.Bakoon ProductsFrom standard volumes like the amplifier series, you can choose optionally a metal film type resistor with low current noise, high accuracy and excellent characteristics, and an induction-winding type resistor that significantly reduces the generation of parasitic inductance, which causes distortion (linking) of signal waveforms that occur on the amplifier internal circuits with magnetic flux. As the accuracy of resistance increases, the amount increases, but it is best to choose according to your preferred music genre.

The "passive attenuator" is a device with a volume control mechanism that is simply constructed, with no amplification elements or buffer circuits such as vacuum tubes and transistors that transmit sound signals to the speakers and power amplifiers installed in the amplifier, and is made up of passive elements and is made up of only passive elements. Since it does not require power and does not have an amplifier circuit, the low frequencies are often easily pushed side by side, but a passive attenuator that is compiled to the minimum necessary has the appeal that is hard to find with a preamp, such as the freshness and resolution of the sound, the vividness of the high frequencies, the amount of information, and good dislodging.
The thornless, unearthed high frequencies of wind instruments and the subtle changes in the piano player's touch are also expressed, and the details of each note of the strings of violins and classical guitars can be seen. The light tone and moderate low range make it comfortable to listen to, and the passive attenuator is a natural, delicate, with a large amount of sound information and freshness. This passive attenuator is especially recommended for those who listen to small or solo compositions, mainly classical music.
