A breakdown of the review per specifications

Design

Volume

Harman Kardon Onyx Studio 4 11,528.66cm³

Volume is the quantity of three-dimensional space taken up by the product's chassis or, in simpler terms, the space the product fills. Harman Kardon Onyx Studio 4 takes up 11,528.66cm³, it is important to know the space that the speaker occupies just so as to ensure that it will easily fit in the available space next to your other gadgets.

Xiaomi Sound Pro's volume is 4,012.12cm³ meaning it occupies more space than the Harman Kardon Onyx Studio 4 by cm³

Weight

Harman Kardon Onyx Studio 4 2,060g
Xiaomi Sound Pro

We prefer a lower weight better because lighter devices are more comfortable to transport. A lower weight is also an advantage for home appliances, as it makes transportation easier, and for many other types of products.

Height

Harman Kardon Onyx Studio 4 260mm
Xiaomi Sound Pro 204.7mm

The height represents the vertical dimension of a device, Harman Kardon Onyx Studio 4 has a height of 260mm.

Xiaomi Sound Pro, at 204.7mm is shorter than the Harman Kardon Onyx Studio 4 with a difference -55.3mm

Width

Harman Kardon Onyx Studio 4 278mm
Xiaomi Sound Pro 140mm

This represents the horizontal dimension of a device, Harman Kardon Onyx Studio 4 has a width of 278mm.

Xiaomi Sound Pro, at 140mm is smaller in width than the Harman Kardon Onyx Studio 4 by -138mm

Thickness

Harman Kardon Onyx Studio 4 159.5mm
Xiaomi Sound Pro 140mm

The thickness (or depth) of Harman Kardon Onyx Studio 4 is 159.5mm, to know the thickness of the speaker you divide its volume(space occupied) by the surface area( length by width)

Xiaomi Sound Pro has a thickness of 140mm, hence less thicker than the Harman Kardon Onyx Studio 4 by -19.5mm

Sound Quality

Has A Subwoofer

Harman Kardon Onyx Studio 4
Xiaomi Sound Pro

A subwoofer is a speaker that delivers lower frequencies in the range of 20 -200Hz, the low frequencies are produced by instruments such as pipe organs, bass guitars, even the kick drums, and any explosive sound effects say in a movie. Devices that have a subwoofer inbuilt give a richer bass sound when listening to bass-heavy music like hip hop.

Both the Xiaomi Sound Pro and Harman Kardon Onyx Studio 4 have a subwoofer

Size Of Subwoofer

Harman Kardon Onyx Studio 4 75mm
Xiaomi Sound Pro

Bigger subwoofers are capable of producing deeper bass sounds. Harman Kardon Onyx Studio 4 has a 75 mm subwoofer

Has Stereo Speakers

Harman Kardon Onyx Studio 4
Xiaomi Sound Pro

Harman Kardon Onyx Studio 4 has stereo speakers, what this means is that Harman Kardon Onyx Studio 4's speakers deliver sound from separate channels on both left and right sides, this creates a richer sound and a better listening experience.

The Xiaomi Sound Pro also has stereo speakers

Driver Unit Size

Harman Kardon Onyx Studio 4 20mm
Xiaomi Sound Pro 38.1mm

The driver unit is the component that produces sound in the device, its size dictates the loudness of the headphone. Harman Kardon Onyx Studio 4 driver unit is 20mm in diameter, bigger drivers are more powerful and can produce better bass.

Xiaomi Sound Pro driver unit is 38.1mm in diameter, making them have a larger driver unit than that of Harman Kardon Onyx Studio 4 by 18.1mm , as many tend to believe that driver units of a bigger size automatically produce better sound quality.

However, large drivers usually have difficulty reproducing high frequencies so yeah, larger drivers are capable of generating louder sound, but this does not mean that they deliver better sound.

Drivers Count

Harman Kardon Onyx Studio 4 2only
Xiaomi Sound Pro

A speaker driver is an individual transducer that converts electrical energy to sound waves. Drivers come in different sizes and modes, but generally, you'll find three types: tweeter driver, which handles the high-frequency treble range (above 2,000 Hz), and midrange driver: which handles the midrange frequencies (200 Hz to 2,000 Hz). Woofer driver: handles the low-frequency bass range (below 200 Hz).

Based on the frequencies they handle more drivers may result in better sound quality, Harman Kardon Onyx Studio 4 has 2 only.

Has A Passive Radiator

Harman Kardon Onyx Studio 4
Xiaomi Sound Pro

A passive radiator is a type of driver in speakers that can get extra power and resonance from a speaker system, usually used in smaller speaker systems. This radiator is called passive because it is not powered by electricity but by air pressure found in speaker cones.

The sound vibrations produced by a passive radiator depend on its mass and the size of its enclosure. It is usually used in combination with a woofer to produce deep, resonant tones that would normally be produced by speakers in large boxes powered by AC.

The Xiaomi Sound Pro and Harman Kardon Onyx Studio 4 both have a passive radiator

Snr - Signal To Noise Ratio

Harman Kardon Onyx Studio 4 80db
Xiaomi Sound Pro

The signal-to-noise ratio is a measure that compares the meaningful sound a speaker produces to the level of noise produced by internal components of that speaker, the higher the number the less perceived noise. Harman Kardon Onyx Studio 4 has an audio signal level of 80 dB higher than the level of noise.

Audio Output Power

Harman Kardon Onyx Studio 4 4 x 15w
Xiaomi Sound Pro 40w

The audio output power of a device is based on the number of speakers and their power in watts Harman Kardon Onyx Studio 4 has 4 x 15W, this is the amount of power the speakers can be loaded with "comfortably".

A higher audio output power results in louder, clearer sounds though this is not the sole factor determining the device's loudness. To get a better understanding of how loud any speaker can get, there are other aspects to look at such as sensitivity, sound pressure, etc.

Xiaomi Sound Pro has an audio output power of 40W

Lowest Frequency

Harman Kardon Onyx Studio 4 50hz
Xiaomi Sound Pro 45hz

Low-frequency response measures if and how well an audio component reproduces low audible frequencies and if it makes any changes to the signal on the way through. Harman Kardon Onyx Studio 4's lowest frequency is at 50Hz, the lower the low-frequency response, the stronger and juicier the bass.

Xiaomi Sound Pro's lowest frequency is at 45Hz, this implies that Harman Kardon Onyx Studio 4 got a juicier bass than the Xiaomi Sound Pro

Highest Frequency

Harman Kardon Onyx Studio 4 20,000hz
Xiaomi Sound Pro 20,000hz

High frequency response measures if and how well a particular audio device reproduces high audible frequencies and if it makes any changes to the signal on the way through. Harman Kardon Onyx Studio 4's highest frequency is at 20,000Hz, the higher the high-frequency response, the clearer and crispier the treble.

Xiaomi Sound Pro's highest frequency is at 20,000Hz, this implies that both devices produce equal treble
