Sound Quality

Has A Subwoofer

Harman Kardon Onyx Studio 4
DemerBox DB2

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.

Size Of Subwoofer

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

The driver unit is basically a mini speaker 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.

Drivers Count

DemerBox DB2 2only

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, DemerBox DB2 has 2 only.

Harman Kardon Onyx Studio 4 has 2 only

Has A Passive Radiator

Harman Kardon Onyx Studio 4
DemerBox DB2

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 DemerBox DB2 both have a passive radiator

Snr - Signal To Noise Ratio

Harman Kardon Onyx Studio 4 80dB

DemerBox DB2 20W

The audio output power of a device is based on the number of speakers and their power in watts DemerBox DB2 has 20W, 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 features to factor in such as sensitivity, sound pressure, etc.
