If you want to set up wireless surround sound loudspeakers you might like to consider cordless loudspeakers to avoid rewiring your home.

Wireless speakers tend to be complex than standard loudspeakers. They incorporate an amp that may have an impact on speaker performance. The cordless receiver also has to be high quality and also there is a great number of diverse products in the marketplace.

Speakers come in various sizes and with different wattage. Usually the higher the power the louder the loudspeaker. High-wattage loudspeakers are important for outdoor uses or maybe if you do have a big area.

The highest loudspeaker wattage will depend on both just how much wattage the speaker components are designed for together with the power rating of the built-in amp. Really don’t be fooled by maximum wattage specs which are often exaggerated by vendors and rather look at the RMS wattage spec.

Both RMS as well as maximum power specs are crucial when you compare various products. The maximum wattage rating should be substantially higher than the RMS rating seeing that audio signals are of varying power and possess big peaks.

Another important spec is the speaker frequency response curve. A few manufacturers will publish the frequency response chart which is perfect for finding out how linear the speaker is going to reproduce music over frequency and presents an excellent clue regarding speaker audio quality.

Harmonic distortion, also known as THD, may also impact the sound quality of the loudspeaker. This phrase is either shown in dB as well as in % and tells just how much the sound is changed from the initial music signal. The cordless receiver, power amplifier in addition to the drivers contribute to distortion. Ensure you compare the output wattage at which the harmonic distortion is specified. If at all possible you will discover harmonic distortion specs for various wattage figures Once the output wattage approaches the maximum rated power, harmonic distortion is going to dramatically grow.

Loudspeakers with bigger wattage rating usually have digital amplifiers that provide greater power efficiency than conventional music amplifiers. Selecting a model with a higher-efficiency amp is generally lighter in weight as it does not need large cooling fans and saves you money on electricity. However, several digital amplifier products experience fairly high audio distortion as a result of nonlinearities of the internal switching stage. Thus pay close attention to the harmonic distortion figure.

Wireless speakers with multiple drivers will need some form of cross-over. This cross-over is often built with passive parts. Normal cross-overs demand relatively big and heavy components if the speaker offers a high wattage. Alternatively, a number of types have independent amps, one for every driver. The audio signal will then be separated into different areas by using tiny and low-cost components before the amp.

It is important to go with a product that features a good-quality cordless receiver. Entry-level speakers with 900 MHz analog receivers are going to introduce lots of noise in addition to audio distortion during the cordless transmission. More modern products make use of digital music transmission and offer better amounts of signal-to-noise ratio in addition to fidelity compared to previous-generation products.

Wireless speakers which use digital transmission either receive uncompressed audio or make use of a standard just like Bluetooth which compresses music to some degree. Bluetooth music transmitters make use of music compression and normally are not able to broadcast to more than one loudspeaker yet provide the benefit of not requiring a separate transmitter.
