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.

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 7 3only

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).

Harman Kardon Onyx Studio 4 has 2 only

Has A Passive Radiator

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 Harman Kardon Onyx Studio 7 both have a passive radiator
