I am going to look at the phrase "power efficiency" which tells you exactly how much cordless loudspeakers squander to help you choose a set of wireless loudspeakers.
The less efficient your cordless loudspeakers are, the more power is going to be wasted which leads to many difficulties: A great deal of squandered energy obviously means larger running cost which means that a more pricey set of cordless speakers might actually in the long term be less costly compared to a cheaper model with lower efficiency. Lower efficiency cordless loudspeakers will dissipate a lot of power as heat. Heat does not dissipate effectively through small surfaces. Consequently low-efficiency cordless speakers require to use heat sinks. These heat sinks consume a good amount of room and make the cordless speakers large and heavy. Further, they raise the expense of the cordless loudspeakers. To help dissipate heat, low-power-efficiency amps need to have adequate air movement. So they can't be placed in areas without circulation. Furthermore, they can't be mounted inside water resistant enclosures.
Wireless loudspeakers that have small efficiency require a bigger power source to output the identical level of audio power as high-efficiency types. Additionally, the thermal stress on the circuit board components as well as amplifier materials is more serious and may lessen the reliability.
Yet, there are a few things to note regarding power efficiency. For starters, this figure will depend on on the level of power that the amp is providing. Since each amplifier will demand a certain level of energy, regardless of the level of energy the amplifier delivers to the loudspeakers, the amplifier power efficiency is higher the more power the amplifier provides and is typically given for the highest power the amp can handle.
To be able to measure the power efficiency, normally a test tone of 1 kHz is fed into the amp and a power resistor connected to the amplifier output to imitate the loudspeaker load. Then the amp output signal is measured and the wattage calculated that the amplifier delivers to the load which is then divided by the total power the amp utilizes. Usually a complete power report is plotted to show the dependency of the efficiency on the output power. For this reason the output power is swept through several values. The efficiency at each value is tested and a efficiency graph created.
Wireless loudspeakers that employ switching-mode amps have a switching stage that causes some amount of non-linear behavior. Thus cordless speakers that use Class-D amps normally offer smaller audio fidelity than types using analog Class-A amplifiers. Therefore you are going to have to base your decision on whether you require small size and low energy consumption or greatest music fidelity. Nevertheless, the latest cordless loudspeakers that use switching-mode music amplifiers, including Class-T amplifiers, offer music fidelity that comes close to that of low-efficiency analog amps and can be built ultra small and lightweight.
