When selecting a brand new set of cordless loudspeakers, you almost certainly are going to take a glimpse at the technical specs. One often found specification is the frequency response. This specification although vital doesn't tell the entire story regarding how good the speakers will sound. You will possibly not completely understand the way in which the frequency response is measured. I will discuss what specifically this specific expression means. Hopefully you will be able to make a much more well informed purchasing decision. A set of wireless loudspeakers are going to transmit and the reproduce an audio signal that is within the frequency response range. If the frequency range is 20 Hz to 20 kHz for example, the wireless loudspeakers could transmit any signals with a frequency higher than 20 Hz and lower than 20 kHz. It might seem the larger the frequency response the better the cordless speakers. That, however, might not always be the case. You should evaluate the specs far more meticulously so that you can properly interpret these.
A set of wireless loudspeakers are transmit and the reproduce a sound signal which is inside the frequency response range. This range is specified by listing 2 frequencies: a lower as well as upper frequency. For example, the lower frequency might be 20 Hz and the upper frequency 20 kHz. Using this spec it seems the cordless loudspeakers could function as a set of HIFI speakers. You could think the greater the frequency response the better the cordless loudspeakers. That, however, may not necessarily be. You should look at the specs a lot more meticulously to be able to adequately interpret them.
On the other hand, the frequency response often is used to deceive shoppers by means of extending the frequency range a great deal beyond the range where the wireless loudspeakers still operate properly and also conceals the reality that the wireless speakers might not be linear. Hence it is best to possess a complete frequency response chart. This type of chart will reveal whether or not there are any kind of major peaks and / or valleys inside the working frequency range. Peaks and valleys can result in colorization of the audio. If possible the cordless loudspeakers ought to have a constant sound pressure level within the complete frequency response apart from the drop off at the lower and upper limit. Aside from the frequency response, a phase response chart will also say a good deal in regards to the functionality as well as sound quality of the wireless loudspeakers.
The conditions under which the frequency response was measured are also necessary to comprehend. Actually amplifiers could have different frequency responses depending on the speaker driver element which is built in.
Mainly modern wireless loudspeakers which use digital or "Class-D" amps will show changes in the frequency response with different driver loads. The reason is the fact that Class-D amps employ switching FETs as the power stage that produce significant amounts of switching components. These components are removed by a filter which is part of the internal speaker amp. The lowpass filter characteristic, on the other hand, heavily varies according to the attached speaker load.
A few of the latest digital amps feed back the audio signal after the lowpass filter so as to compensate for this drawback and to make the frequency response of the amplifier independent of the connected driver load. However, if the amplifier is not designed properly, this type of feedback could potentially cause instability and lead to loud noise being created by the amp if particular speakers are attached. Different amps make use of transformers and provide outputs for various loudspeaker loads. In addition to improving upon the frequency response of the amp, this technique normally furthermore enhances the amplifier efficiency.
