The integrated design also makes this product more integrated into the home decoration. The driver units are all concentrated in the circular cavity, and the buttons are laid out on the frame. In terms of color, there are five colors in black, white, red, blue, and gray.

The Driver

After removing the grille, let’s take a look at the internal layout. At the top is a white passive low-frequency radiator, and you can see the letters Harman/Kardon logo.

The two sides are equipped with tweeters, and the tweeter adopts a 20mm silk dome driver, which can see natural silk weaving.

There are two mid-woofer speakers below, using a 75mm rubber-edged composite basin unit. When the music is played, it will move linearly, generate airflow in the cabinet, and drive the bass radiator for long-stroke propulsion.

There is a small hole at the bottom, with a built-in microphone in the hole. Thus, hands-free calls can be made when mobile phone calls. To ensure the clarity of the call, noise reduction technology is also used.

Sound Performance

The Harman Kardon Onyx Studio 3 bluetooth speaker is a two-channel, two-way stereo system. It has an independent tweeter. As a result, the two domes have good treble quality. Its high-frequency characteristics are mainly expressed as delicate and soft, transparent. When listening to popular music, the energy of the tweeters is enough.

If you are a high-frequency enthusiast, remove the speaker’s grille, the treble details will be richer, the penetrating power will be more substantial.

The midrange has a thickness, and the vocals are full. The midrange performance of the 3-inch unit is satisfactory, without too many adjectives to describe it.

Besides, this pair of mid-woofers looks like a paper cone speaker at first, but if you carefully observe the surface of the driver, you can find many very tiny fiber filaments, which are more delicate than the wool. So it should be a new type of composite material.

The low-frequency characteristics of this speaker are powerful, sinking, and stable. Mainly due to the two low-frequency radiators. Generally speaking, a 3-inch mid-woofer speaker cannot have such an extensive dynamic range. Only through the designer’s ingenious design and passive speakers can the bass be enhanced in a closed cabinet.

The depth of the dive creates a sense of shock; even compared to the 4-inch 5-inch woofer, it is not inferior, and the transient response speed is also timely. Listening to Onyx Studio3 has the effect of a small subwoofer.

The sound of Onyx Studio 3 is bright and not excessive, and it can grasp the performance of one degree. It allows you to savor the rhythm of jazz music by yourself and will enable people in a room to hear every electronic item. The drums are blooming in the chest.
