Rear volume control computer speakers

From the back side

— the knob mounted on the rear panel of the speaker is not very convenient for frequent volume changes — you usually have to find it by touch, and some free space around the speaker is required to access it. So on such speakers it is most convenient to initially select a certain optimal sound level, and then, if necessary, adjust the volume through the computer's software settings and not reach out to the regulator once again. Therefore, this option is quite rare. On the other hand, such invisibility has its advantages: acoustics acquires the most accurate appearance, without unnecessary small elements on the outside.
