Loudspeakers are part of the standard equipment of every classroom or seminar room. Despite of a physical power switch, the boxes are usually not switched off, which means they constantly consume electricity: 24 hours a day, 365 days a year.
It is not a surprise that the standby consumption quickly becomes of interest as it could gain energy costs, not only because of the recent explosion of electricity costs but also because of the fact that schools or trainingscenters typically have many rooms.
Here's an example calculation:
Let's assume that active speakers are used on 200 days a year for about 2 hours, or better to say the run in stand-by for 22 hours = 4.400 hours
Add the remaining days like weekends, holidays, etc. = 3960 hours
Total: 8.360 hours
We have tested an found that the stand-by consumption of a popular active speaker set is 7,9 watts higher than the consumption of the AktivboxSet² 50+*.
Multiply this with the standby time the additional consumption is 66 kw/h per year.
According to BDEW the average cost of a kwh 2021 in Germany was 32,16 Cents.
This results in a cost saving of around 21 € in 2021 and per room!
Not to mention the CO² emissions that can be saved over the years!
