Wireless loudspeaker providers often release the frequency response of their products and solutions that, unfortunately, won't always show you a great deal concerning the sound quality. I am going to describe the meaning of this expression and even provide some suggestions on how to interpret it whilst looking for a set of cordless speakers. A set of wireless speakers are able to only function inside of a specific frequency range. Any kind of signals just outside of this range will be eliminated. Because of this the frequency response gives an essential hint with regards to whether a certain set of wireless loudspeakers could be well suited for a certain application. If the frequency range is 20 Hz to 20 kHz for instance, the cordless speakers could transmit all signals with a frequency greater than 20 Hz and lower than 20 kHz. You could be tempted to choose a set ofcordless speakers that gives the biggest frequency response. On the other hand, there is far more to understanding a cordless speakers's overall performance than simply understanding this simple range.
Seems like there are various methods which producers make use of while specifying the frequency response. Ordinarily, the frequency response displays the normal operating range of the cordless speakers. Within this range, the sound pressure level is basically constant. At the lower and upper cutoff frequencies the gain will drop by no more than 3 decibels.
A large frequency response does not always mean the cordless speakers provide excellent audio quality. As an example a set of wireless loudspeakers having a frequency response between 30 Hz and 15 kHz may sound better than another set having a response between 10 Hz and 30 kHz. Moreover, every supplier, it appears, implements a different procedure for specifying the lowest and highest frequency of their wireless loudspeakers. The normal convention is to display the frequency range within which the sound pressure level of the speakers is going to drop at most 3 dB from the nominal level.
To better comprehend the frequency response behavior of a particular model, you should try to determine under which circumstances the response was calculated. You may find these details in the data sheet of the cordless loudspeakers. Then again, a lot of producers are not going to publish those in which case you ought to get in touch with the manufacturer directly. One condition which may impact the frequency response is the impedance of the loudspeaker driver built into the cordless loudspeakers. Standard speaker driver impedances vary from 2 to 16 Ohms. The lower the speaker driver impedance the higher the burden for the internal amplifier.
To better comprehend the frequency response behavior of a specific model, you should try to find out under which conditions the response was calculated. You might find this info in the data sheet of the cordless speakers. However, a lot of makers will not publish those in which case you may need to get in touch with the maker directly. The fact is that lots of amps which are incorporated into the wireless loudspeakers are going to work differently with different speaker loads. This is because of the fact that different loudspeaker loads will result in changes to the behavior of the output power stage of the amplifier. This change is most obvious with many cordless speakers that use digital amplifiers, otherwise known as Class-D amps. Class-D amplifiers employ a lowpass filter inside their output to be able to suppress the switching components that are generated through the internal power FETs. The lowpass filter characteristic, however, heavily varies according to the connected speaker load.
A number of the newest digital amps feed back the music signal after the lowpass filter to be able to compensate for this tradeoff and also to make the frequency response of the amplifier independent of the attached driver load. However, if the amp is not designed well, this type of feedback may cause instability and also cause loud noise being generated by the amplifier if particular speakers are connected. An additional method uses audio transformers between the power stage of the amplifier and several outputs. Every output is designed to connect a different speaker load. This approach makes sure that the amplifier will be loaded equally and in addition increases amplifier efficiency.
