When selecting a new set of cordless speakers, you most likely will take a look at the technical specifications. An often found parameter is the frequency response. This parameter although crucial won't tell the full story with regards to how great the loudspeakers are going to sound. I am going to clarify the meaning of this expression and also offer some suggestions on how to interpret it while looking for a set of cordless loudspeakers.
A set of wireless speakers are able to only function inside of a particular frequency range. Any signals outside this range are going to be removed. As such the frequency response gives a crucial hint with regards to whether or not a specific set of wireless loudspeakers may be well suited for a specific application. This range is specified by showing two frequencies: a lower and upper frequency. By way of example, the lower frequency could be 20 Hz and the upper frequency 20 kHz. From this specification it seems like the cordless loudspeakers would be able to function as a set of HIFI loudspeakers. However, there's much more to comprehending the wireless loudspeakers's performance than just considering these figures.
In fact, a set of cordless loudspeakers with a frequency response from 10 Hz to 30 kHz can actually have much worse sound quality than a set that provides a frequency response from 20 Hz to 15 kHz. Different producers often utilize different methods in order to determine frequency response. The most widely used technique is to describe the frequency response as the frequency range within which the cordless loudspeakers will have fairly constant sound pressure level with a maximum drop of 3 decibel (dB). Typically the decline in sound pressure level is greatest at the upper and lower frequency.
You additionally may need to look at the conditions under which the frequency response was calculated. You typically are not going to find any kind of information about the measurement conditions, unfortunately, in the producer's data sheet. The fact is that a lot of amps which are incorporated into the wireless speakers are going to behave differently with different speaker loads. This is due to the fact that various speaker loads can cause changes to the behavior of the output power stage of the amp.
Mostly contemporary wireless speakers which use digital or "Class-D" amps will show changes in the frequency response with various driver loads. The main reason is the fact that Class-D amps employ switching FETs as the power phase which create a lot of switching components. These components are eliminated by using a filter that is part of the internal speaker amp. The lowpass filter characteristic, however, greatly depends on the attached speaker load.
A few amplifiers include feedback to compensate for changes in gain because of different connected loads. An additional strategy is to provide dedicated outputs for various loudspeaker driver impedances which are connected to the amp power stage via audio transformers.
