How Much Power Do My Stereo Speakers Really Need?

This is normally specified at full load and nominal input voltage.

Understanding Speaker Power Rating Specifications

In other words, don't turn up the amp so high that it clips. I-T, I-T, MAVZ With the tools and advice in this article, you should be able to purchase or recommend a power amplifier with the right amount of wattage for the style of music and venue. Total power both channels combined W: Load Regulation — The amount of variation of the output that occurs with variations of the load from minimum to maximum, stated in percent.

Current Limited — A circuit in which, if a maximum current value reached or approaches a short circuit , voltage source voltage will drop as power demand increases.


The bulb is intended to operate using a particular source voltage and frequency. In the calculator's Peak Headroom field, enter 6 dB for rock music that is compressed or limited, or enter 20 to 25 dB for uncompressed live music.

The input power consumption will evidently be greater. How many watts will we need? Other losses occur in the capacitors and inductors especially when cheap, high resistance components are used.

There are multiple variables to consider when seeking out the best solar panels on the market. We will usually find it listed alongside all the other speaker specifications - most of which we don't understand right? If the amplifier power specs are rated at 8 ohms, then the speaker power specs should be measured at 8 ohms if you are to compare them.

Showcase Share your renewable energy project with the entire altE community. However, if the watts value is a peak value sometimes called peak music power , the the average power it can handle would be more like 70 watts. Efficiency By July 1, 0. Simply count up from there: Suppose you need to supply watts for peaks, and your speaker's continuous power handling is watts.

This means buying a higher wattage supply which may be more expensive.

Power Ratings (typical) for Common Appliances altE

Howard W. Personal tools Create account Log in. Here's how to do it:. It can be argued that it is better to have an amplifier that is more powerful than the speaker ratings, rather than less. Connect two loudspeakers in parallel on each channel. It might be called IEC rating or Power capacity. No, that's just the maximum rated supply. If you are purchasing a separate power supply and looking for a more efficient one look for the 80 Plus logo on the power supply.
