Turtlebox Gen 2 Vs. Harman Kardon Onyx Studio 4 Review In Detail

Design

Ingress Protection (Ip) Rating

Harman Kardon Onyx Studio 4
Turtlebox Gen 2 IP67

Ingress protection ratings refer to the level of protection offered by an electrical enclosure, against solids and liquids. The letters 'IP' are followed by two numerals The first number of the IP rating refers to protection against solids say dust, while the second refers to protection against liquid.

Scoring IP67, the Turtlebox Gen 2's rating is read as, the first value of 6 denotes that they are completely dust proof, and the second number of 7 means that they are protected against temporary immersion in water under set conditions, say 1 metre for 30 minutes.

Volume

Harman Kardon Onyx Studio 4 11,528.66cm³
Turtlebox Gen 2

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

Weight

Sound Quality

Has A Subwoofer

Harman Kardon Onyx Studio 4
Turtlebox Gen 2

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 Harman Kardon Onyx Studio 4 and Turtlebox Gen 2 have a subwoofer

Size Of Subwoofer

Harman Kardon Onyx Studio 4 75mm
Turtlebox Gen 2 190.5mm

Bigger subwoofers are capable of producing deeper bass sounds. Turtlebox Gen 2 has a 190.5 mm subwoofer

Harman Kardon Onyx Studio 4 has a 75 mm subwoofer

Has Stereo Speakers

Harman Kardon Onyx Studio 4
Turtlebox Gen 2

Turtlebox Gen 2 has stereo speakers, devices with stereo speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better listening experience.

The Harman Kardon Onyx Studio 4 also has stereo speakers

Driver Unit Size

Harman Kardon Onyx Studio 4 20mm
Turtlebox Gen 2 63.5mm

The driver unit is basically a mini speaker that produces sound in the device, its size dictates the loudness of the headphone. Turtlebox Gen 2 driver unit is 63.5mm in diameter, bigger drivers are more powerful and can produce better bass.

Harman Kardon Onyx Studio 4 driver unit is 20mm in diameter, which means that they have a smaller driver unit than that of Turtlebox Gen 2 by 43.5mm , many people have a misconception 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 can generate louder sound, but this does not mean that they produce better sound.

Drivers Count

Harman Kardon Onyx Studio 4 2only
Turtlebox Gen 2 1only

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, Turtlebox Gen 2 has 1 only.

Harman Kardon Onyx Studio 4 has 2 only

Has A Passive Radiator

Harman Kardon Onyx Studio 4
Turtlebox Gen 2

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 Harman Kardon Onyx Studio 4 and Turtlebox Gen 2 both have a passive radiator

Snr - Signal To Noise Ratio

Harman Kardon Onyx Studio 4 80dB
Turtlebox Gen 2 80dB

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. Turtlebox Gen 2 has an audio signal level of 80 dB higher than the level of noise.

The Harman Kardon Onyx Studio 4, at 80dB has the same audio signal as the Turtlebox Gen 2.

Audio Output Power

Harman Kardon Onyx Studio 4 4 x 15W
Turtlebox Gen 2 120W

The audio output power of a device is based on the number of speakers and their power in watts Turtlebox Gen 2 has 120W, 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 better understand how loud any speaker can get, there are other aspects to look at such as sensitivity, sound pressure, etc.

Harman Kardon Onyx Studio 4 has an audio output power of 4 x 15W

Lowest Frequency

Harman Kardon Onyx Studio 4 50Hz
Turtlebox Gen 2 20Hz

Low-frequency response measures if and how well a particular audio component reproduces low audible frequencies and if it makes any changes to the signal while at it. Turtlebox Gen 2's lowest frequency is at 20Hz, the lower the low-frequency response, the stronger and juicier the bass.

Harman Kardon Onyx Studio 4's lowest frequency is at 50Hz, this implies that Harman Kardon Onyx Studio 4 got a juicier bass than the Turtlebox Gen 2

Highest Frequency

Harman Kardon Onyx Studio 4 20,000Hz
Turtlebox Gen 2 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. Turtlebox Gen 2's highest frequency is at 20,000Hz, the higher the high-frequency response, the clearer and crispier the treble.

Harman Kardon Onyx Studio 4's highest frequency is at 20,000Hz, this implies that both devices produce equal treble
