Cordless loudspeaker companies frequently publish the frequency response of their solutions which, however, doesn't always tell you a great deal concerning the sound quality. You may not fully grasp precisely how the frequency response is calculated. I'll clarify what precisely this specific expression means. I hope you will be able to make a much more well informed buying decision. Wireless loudspeakers are created to transmit and the reproduce a music signal to medium or high volume. Suppliers usually show the frequency range over which the cordless speakers work. This range is specified by listing 2 frequencies: a lower and also upper frequency. For example, the lower frequency might be 20 Hz and the higher frequency 20 kHz. From this specification it seems like the cordless speakers can function as a set of HIFI speakers. You may be lured to select a set ofcordless speakers that provides the largest frequency response. Yet, there's far more to comprehending a wireless loudspeakers's functionality than merely knowing this simple range.
A set of wireless speakers are transmit and the reproduce a sound signal that is within the frequency response range. If the frequency range is 20 Hz to 20 kHz for example, the wireless loudspeakers would be able to transmit any signals with a frequency higher than 20 Hz and lower than 20 kHz. It might seem the larger the frequency response the higher quality the wireless loudspeakers. That, however, might not necessarily be. You have to check out the specs far more meticulously in order to adequately interpret these.
A large frequency response doesn't imply the wireless loudspeakers provide great audio quality. For instance a set of cordless speakers having a frequency response between 30 Hz and 15 kHz might sound better than another set with a response between 10 Hz and 30 kHz. Also, every manufacturer, it seems, utilizes a different technique of specifying the lowest and maximum frequency of their cordless loudspeakers. The standard convention is to display the frequency range within which the sound pressure level of the speakers will decrease a maximum of 3 dB from the nominal level. Nevertheless, numerous companies overlook this particular established practice. They push the lower frequency and higher frequency to where the wireless loudspeakers hardly have any sound response. Furthermore, these numbers tell almost nothing about how linear the cordless loudspeakers are operating within this range. Subsequently it is ideal to have a complete frequency response chart. This kind of graph will show whether or not there are any significant peaks or valleys within the operating frequency range. You may even wish to request a phase response diagram which also provides vital hints in regards to the audio quality.
On the other hand, several companies push this standard to the limit and will show an upper frequency where the wireless speakers are going to hardly produce a beep any longer. Also, simply considering these 2 figures doesn't say a lot concerning the linearity of the frequency response. Consequently it is better to possess a full frequency response document. This sort of chart is going to show if there are any kind of substantial peaks and valleys inside the working frequency range. You may also want to demand a phase response chart that provides essential hints concerning the quality of sound.
The frequency response of Class-D amplifiers shows the largest change with various speaker loads due to the integrated lowpass filter that removes switching noise from the speaker amplifier's signal. However, the frequency response of the amplifier now will depend on the loudspeaker driver load since the behavior of this lowpass filter is influenced by the load impedance. Usually the lower the speaker driver load impedance the lower the upper cut-off frequency of the amp
Several of the latest digital amps feed back the audio signal after the lowpass filter so as to compensate for this tradeoff and to make the frequency response of the amp independent of the connected driver load. However, if the amplifier is not constructed well, this kind of feedback could cause instability and bring about loud noise being produced by the amplifier if certain speakers are connected. Another approach is to offer specific outputs for various speaker driver impedances that are connected to the amplifier power stage by using audio transformers.
