Wireless speaker vendors frequently release the frequency response of their items that, sad to say, doesn't automatically show you a lot about the quality of sound. To help you make a more intelligent buying decision, I am going to make clear what this spec means and how to understand it. This ideally is going to guarantee you're going to get the perfect wireless loudspeakers for your project. A set of cordless loudspeakers are transmit and the reproduce a sound signal which is inside the frequency response range. If the frequency range is 20 Hz to 20 kHz for example, the wireless speakers would be able to transmit any signals with a frequency higher than 20 Hz and lower than 20 kHz. Yet, there is certainly more to understanding the wireless loudspeakers's functionality than just considering these numbers.
Seems like there are lots of techniques that suppliers make use of whilst specifying the frequency response. The standard convention is to display the frequency range inside which the sound pressure level of the loudspeakers is going to decrease no more than 3 dB from the nominal level.
It seems there are various approaches which producers use whilst specifying the frequency response. Typically, the frequency response shows the standard operating range of the wireless loudspeakers. Within this range, the sound pressure level is essentially constant. At the upper and lower cutoff frequencies the gain is going to decrease by at most 3 decibels.
The circumstances under which the frequency response was determined may also be important to understand. The fact is amps might have different frequency responses depending on the speaker driver element which is built in.
The frequency response of Class-D amplifiers shows the largest change with different speaker loads because of the built-in lowpass filter that eliminates switching noise from the speaker amplifier's signal. The lowpass filter characteristic, however, heavily is dependent upon the attached speaker load.
A number of amps incorporate feedback to be able to compensate for changes in gain caused by different attached loads. Different amps make use of transformers and provide outputs for different loudspeaker loads. Apart from improving upon the frequency response of the amp, this approach usually furthermore enhances the amplifier efficiency.
