Wireless speaker companies normally present the frequency response of their products and solutions which, sad to say, will not automatically explain to you a great deal concerning the quality of sound. You may possibly not fully grasp the way in which the frequency response is calculated. I'll describe what precisely this specific expression means. Hopefully you'll be able to make a more informed buying decision. A set of cordless speakers are transmit and the reproduce a sound signal which is within the frequency response range. This range is specified by listing 2 frequencies: a lower in addition to upper frequency. For instance, the lower frequency may be 20 Hz and the higher frequency 20 kHz. Using this specification it seems like the cordless loudspeakers would be able to operate as a set of HIFI loudspeakers. It might seem the greater the frequency response the better the cordless loudspeakers. That, however, will not necessarily be. You should consider the specifications more carefully in order to properly understand all of them.
A set of wireless speakers are only able to function within a particular frequency range. Any kind of signals outside this range will be removed. As a result the frequency response gives a significant clue about whether a certain set of cordless speakers may be appropriate for a particular use. If the frequency range is 20 Hz to 20 kHz as an example, the cordless loudspeakers could transmit all signals with a frequency greater than 20 Hz and less than 20 kHz. You might be tempted to go with a set ofcordless loudspeakers that offers the greatest frequency response. However, there is certainly more to knowing a wireless loudspeakers's functionality than only knowing this simple range.
Then again, various makers push this standard to the limit and may show a maximum frequency where the wireless loudspeakers will barely generate a beep anymore. Also, simply examining these 2 numbers won't say a lot concerning the linearity of the frequency response. Hence it is better to possess a full frequency response graph. Such a chart will show whether there are any kind of considerable peaks and valleys within the operating frequency range. Peaks in addition to valleys might cause colorization of the audio. Ideally the sound pressure level of the cordless loudspeakers ought to be linear through the entire working range.
To better comprehend the frequency response behavior of a specific type, you should make an effort to figure out under which circumstances the response was measured. You might find this information in the data sheet of the cordless loudspeakers. Then again, a lot of manufacturers won't show these in which case you might need to get in touch with the manufacturer directly. In fact amplifiers may have different frequency responses depending on the loudspeaker driver element that is built in.
In order to better understand the frequency response behavior of a specific model, you should attempt to figure out under which circumstances the response was determined. You will probably find this info in the data sheet of the wireless speakers. However, many manufacturers won't show those in which case you may need to make contact with the producer directly. In fact amps might have different frequency responses depending on the loudspeaker driver element which is built in. This change is most obvious with a lot of cordless speakers that use digital amplifiers, also called Class-D amps. Class-D amps use a lowpass filter in their output as a way to reduce the switching components which are generated from the internal power FETs. Yet, the frequency response of the amplifier now varies according to the loudspeaker driver load considering that the behavior of this lowpass filter is influenced by the load impedance. Commonly the lower the speaker driver load impedance the lower the upper cut-off frequency of the amp
Various amp topologies offer a method to compensate for variations in the amplifier gain with different loudspeaker loads. One of those approaches uses feedback. The amplifier output signal after the interior lowpass is input to the amplifier input for comparison. If not designed correctly, this approach could cause instability of the amplifier though. Another technique makes use of audio transformers between the power stage of the amp and various outputs. Each output is designed to attach a different speaker load. This method ensures that the amplifier is going to be loaded equally and also improves amplifier power efficiency.
