When buying a brand new set of wireless speakers, it is likely you are going to take a look at the technical specs. An often found parameter is the frequency response. This parameter even though critical will not tell the entire story relating to how well the loudspeakers will sound. You will possibly not fully understand just how the frequency response is calculated. I am going to discuss what precisely this expression means. Ideally you'll be able to make a more educated purchasing decision.
A set of wireless speakers are going to transmit and the reproduce a sound signal which is inside the frequency response range. Typically a lower and upper frequency are listed, just like 20 Hz - 20 kHz. This kind of spec shows that the wireless loudspeakers have the capacity to transmit and then reproduce audio inside that frequency range. You could think the greater the frequency response the better the wireless loudspeakers. That, however, will not necessarily be the case. You should glance at the specs more closely so that you can adequately understand all of them.
Yet, the frequency response commonly is used to mislead shoppers by means of stretching out the frequency range far past the range in which the wireless speakers still work properly and also hides the fact that the wireless loudspeakers may not be linear. A complete frequency response chart, on the other hand, will show if there are any peaks or valleys and also show how the frequency response is to be understood. Also you can desire to request a phase response diagram that also provides vital clues in regards to the audio quality.
In order to better comprehend the frequency response behavior of a certain type, you should try to determine under which conditions the response was measured. You will probably find this info in the data sheet of the wireless speakers. However, the majority of makers won't publish these in which case you may need to make contact with the producer directly. One condition which can impact the frequency response is the impedance of the speaker driver built into the cordless speakers. Normal loudspeaker driver impedances vary from 2 to 16 Ohms. The lower the loudspeaker driver impedance the higher the strain for the internal amplifier.
This change is most apparent with many cordless loudspeakers that use digital amps, referred to as Class-D amplifiers. Class-D amplifiers use a lowpass filter within their output to be able to reduce the switching components that are generated through the internal power FETs. The lowpass filter characteristic, however, greatly depends on the attached speaker load.
Various amps incorporate feedback as a way to compensate for changes in gain due to different connected loads. Another approach utilizes audio transformers between the power stage of the amplifier and several outputs. Each output is designed to attach a different loudspeaker load. This approach makes sure that the amplifier will be loaded equally and also increases amplifier efficiency.
