Let me take a look at the phrase "power efficiency" that informs you of how much wireless speakers squander to guide you choose a pair of wireless speakers.
The less efficient your cordless loudspeakers are, the more power is going to be squandered which results in many issues: Wireless speakers that have small power efficiency are going to squander some power. It's smart to be aware of the added energy cost when choosing between a high- and low-efficiency product. The wasted energy is radiated by the wireless speakers as heat. Heat doesn't radiate well from small surfaces. For that reason low-efficiency wireless loudspeakers need to use heat sinks. These heat sinks consume a fair amount of space and make the cordless speakers large and heavy. Further, they increase the cost of the cordless loudspeakers. Low-efficiency cordless speakers additionally need a great deal of circulation around the wireless loudspeakers. So they can't be put in close spaces or inside air-tight enclosures.
Low-efficiency models need more overall energy to create the identical level of audio power as high-efficiency types. Thus they require a larger power source which makes the wireless loudspeakers costlier to build. Further, because of the large level of heat, there will be considerably higher thermal stress on the electrical elements and also interior materials that might cause reliability problems. In contrast, high-efficiency cordless loudspeakers can be produced small and lightweight.
Please be aware, however, that efficiency will depend on just how much energy the amp delivers at a given moment. Since each amplifier will require a specific amount of energy, regardless of the level of energy the amp delivers to the loudspeakers, the amp power efficiency is higher the more energy the amp provides and is typically specified for the maximum power the amplifier can handle.
To figure out the power efficiency, the audio energy that is consumed by a power resistor that is attached to the amplifier is divided by the overall power the amp utilizes whilst being fed a constant sine wave signal. Generally a complete power report is plotted to display the dependency of the efficiency on the output power. Because of this the output power is swept through different values. The efficiency at each value is tested and a efficiency plot created.
When selecting a set of wireless speakers you will have to weigh efficiency versus fidelity as wireless speakers which employ low-efficiency analog amps often provide the largest audio fidelity whilst digital products will have greater distortion. Then again, digital amps have come a long way and are providing better audio fidelity than ever before. Cordless loudspeakers which make use of Class-T amps come close to the audio fidelity of types that have analog amps. Subsequently picking a pair of wireless speakers which utilize switching amplifier with great audio fidelity is now feasible.
