Design
1.volume
903.24cm³
Volume is the quantity of three-dimensional space enclosed by the product's chassis or, in simpler terms, the space the product occupies.
2.drivers count
2
A speaker driver is an individual transducer that converts electrical energy to sound waves. More drivers may result in better sound quality.
3.control panel placed on a device
Sony SRS-XB21
There is a control panel on the device body, so you can easily access the volume control or remote without having to interact with a cable or another device it's connected to.
4.driver unit size
