When you are about to purchase brand new cordless loudspeakers, you could be asking yourself how efficiently your wireless speakers function. I am going to show you exactly what the term „power efficiency“ stands for and why you need to take a closer look at this figure throughout your selection of brand new cordless speakers.
The less efficient your cordless speakers are, the more power is going to be wasted which results in a number of problems: Wireless speakers that have low efficiency will waste some power. It’s smart to bear in mind the additional power cost when choosing between a high- and low-efficiency type. The wasted energy is radiated by the cordless loudspeakers as heat. Cordless loudspeakers that have small efficiency normally have several heat sinks to help dissipate the wasted power. Heat sinks as well as fans are heavy, consume space and also generate noise. Low-efficiency cordless loudspeakers additionally need a good amount of circulation around the wireless speakers. Thus they can’t be placed in close spaces or inside air-tight enclosures.
Because low-efficiency wireless loudspeakers are going to deliver merely a small percentage of the energy consumed by the amplifier as useful audio power, the amplifier needs a bigger power supply than high-efficiency versions leading to more expensive. An increased amount of heat triggers extra stress on elements. The lifespan of the wireless loudspeakers could be decreased and reliability might be compromised. High-efficiency wireless loudspeakers in contrast don’t suffer from these issues and may be constructed small.
When trying to find a set of cordless loudspeakers, you’ll find the efficiency in the data sheet. This figure is usually shown as a percentage. Analog Class-D amplifiers provide a power efficiency of close to 25% whilst switching-mode amps provide up to 98%. From the efficiency percentage you’ll be able to compute how much power the amplifier will squander. An amp which has a 50% efficiency will squander 50 % of the consumed power. An amp that has 90% efficiency will waste 10%.
What’s less well-known about efficiency is the fact that this value is not fixed. In reality it varies based on how much power the amplifier provides. For that reason occasionally you can find efficiency figures for various power levels within the data sheet. Each audio amplifier will consume a certain level of power regardless of whether or not it supplies any kind of power to the loudspeaker.

Because of this the lower the energy the amplifier delivers, the smaller the power efficiency. As a consequence audio manufacturers normally specify the efficiency for the highest audio power that the amplifier can deliver.
The measurement setup of amp efficiency utilizes a power resistor that is connected to the amp. The amplifier itself is being fed a constant-envelope sine-wave tone. Next the energy absorbed by the resistor is tested and divided by the energy the amplifier uses. Given that the efficiency is dependent upon the audio power, commonly the output power is varied and an efficiency curve created which will show the amplifier efficiency for every level of output power.
When picking a set of cordless loudspeakers you have got to weigh efficiency versus fidelity considering cordless speakers which utilize low-efficiency analog amplifiers often provide the highest music fidelity while digital types will have bigger distortion. A number of more sophisticated wireless speakers, like products that include Class-T amps, are able to lessen music distortion to levels close to those of types utilizing analog music amplifiers and also are able to accomplish high signal-to-noise ratio. Picking one of these types of wireless loudspeakers will deliver high power efficiency and at the same time large audio fidelity.
