The frequency response is the most often found parameter in order to characterize cordless loudspeakers. Nevertheless, it might regularly be deceptive and might possibly not give a good indication of the audio quality. I will clarify the meaning of this expression and also provide some recommendations on how to interpret it whilst searching for a set of cordless loudspeakers.
It seems like there are lots of methods which makers use whilst specifying the frequency response. Usually, the frequency response displays the normal operating range of the wireless loudspeakers. Inside this range, the sound pressure level is largely constant. At the lower and upper cutoff frequencies the gain will drop by no more than 3 decibels.
Apparently there are various ways that manufacturers use while specifying the frequency response. Generally, the frequency response shows the normal operating range of the wireless speakers. Within this range, the sound pressure level is largely constant. At the upper and lower cutoff frequencies the gain is going to decrease by at most 3 decibels. However, a lot of producers dismiss this convention. They push the lower frequency and higher frequency to where the wireless loudspeakers hardly provide any kind of sound response. Furthermore, these figures tell absolutely nothing about precisely how linear the cordless loudspeakers are operating within this range. If possible you should attempt to get a frequency response diagram from the producer. In this diagram, you will discover how the cordless loudspeakers behave within the frequency response range. It's also possible to discover any kind of peaks and valleys the cordless speakers might have. Peaks and valleys could cause colorization of the audio. If possible the cordless loudspeakers should have a constant sound pressure level within the entire frequency response excluding the drop off at the lower and upper limit. Aside from the frequency response, a phase response diagram will also tell a lot regarding the functionality as well as sound quality of the cordless speakers.
On the other hand, the frequency response commonly is utilized to deceive customers by way of stretching the frequency range a great deal past the range where the wireless loudspeakers still function properly and in addition covers up the fact that the cordless loudspeakers may not be linear. If possible you ought to make an effort to obtain a frequency response chart from the manufacturer. In this diagram, you will find the way the cordless loudspeakers behave inside the frequency response range. It's also possible to discover any kind of peaks and valleys the cordless speakers could have. Peaks in addition to valleys could cause colorization of the sound. If at all possible the sound pressure level of the cordless loudspeakers should be linear throughout the entire operating range.
The frequency response of Class-D amplifiers shows the biggest change with different speaker loads due to the built-in lowpass filter which removes switching noise from the speaker amplifier's signal. The lowpass filter characteristic, on the other hand, greatly depends on the connected speaker load.
Some amplifier topologies offer a method to compensate for variations in the amplifier gain with various speaker loads. One example of these approaches uses feedback. The amplifier output signal following the internal lowpass is input to the amplifier input for comparison. If not created properly, this method could potentially cause instability of the amp however. Another approach makes use of audio transformers between the power stage of the amplifier and several outputs. Each output is designed to connect a different loudspeaker load. This method makes certain that the amplifier is going to be loaded equally and in addition increases amplifier power efficiency.
