Information On Picking Out Good-Quality Cordless Speakers

By Mike Hunter


I want to provide you with some information to assist you select a pair of wireless loudspeakers from the multitude of available products. Cordless loudspeakers are a great option for placing speakers in many rooms of your house with no need of placing cabling. Also, these types of speakers are great for adding surround sound to your TV without running lots of speaker cord across the room.

Wireless loudspeakers will be more challenging to pick than normal loudspeakers given that they encompass an amp and also a cordless receiver. Different products differ in quality of each of these components.

If you have a big area then you may wish to pick a speaker which has a large power as a way for the loudspeaker to get sufficiently loud.

The built-in amplifier as well as the transducers determines the level of power the speaker can handle. Speaker vendors are going to either provide maximum or RMS power ratings. RMS power is much more objective than maximum wattage given it gives much more clues regarding the actual amplifier power handling and also amp power supply. Maximum wattage is often exaggerated by loudspeaker producers since the speaker can only endure this level during brief bursts of time. Audio signals, however, have varying power. As a result preferably you should have both power ratings. The RMS spec allows you to evaluate loudspeakers a lot more objectively however the speaker must offer a maximum power handling that is considerably bigger than the RMS rating in order to avoid clipping of the music during peaks.

Another important spec is the frequency response that shows over which frequency range the loudspeaker may recreate audio although it is best to look at the complete frequency response graph when comparing speakers.

The total-harmonic-distortion phrase, also known as THD, will show exactly how much the sound will be altered by the internal audio amplifier in addition to drivers. Be sure you examine the output power at which the harmonic distortion is specified. If at all possible you can find harmonic distortion numbers for several power figures Once the output power approaches the highest specified wattage, harmonic distortion is going to dramatically grow.

In case you pick a type with a large speaker power, it's possible you'll favor a loudspeaker which has a digital amp due to the high amp efficiency compared to analogue amplifiers. Digital amps often have higher harmonic distortion than analog amplifiers. This distortion is in part a result of the switching FET stage of the amp. Wireless speakers with a number of drivers will require some form of cross-over. This crossover is usually realized with passive parts. Alternatively, some brands have independent amplifiers for each driver. In this case the gain of each amplifier usually can be modified individually.

The receiver which picks up the wireless music either from a transmitter or coming from a wireless network or Bluetooth signal also has a significant impact on sound quality. For best sound quality, you may want to refrain from 900 MHz analogue cordless transmission that naturally has a low signal-to-noise ratio and instead choose a receiver which uses a digital music signal.

It is recommended to pick a model that features a good-quality cordless receiver. Entry-level loudspeakers with 900 MHz analogue receivers will create plenty of noise as well as audio distortion during the wireless transmission. More modern brands use digital audio transmission and offer enhanced amounts of signal-to-noise ratio and fidelity compared to previous-generation products. Perhaps you may opt to choose a model which utilizes uncompressed music transmission for optimum results and also is capable of transmitting to several loudspeakers from a single transmitter to help you install loudspeakers in various rooms of your property.
