Wireless speaker companies typically show the frequency response of their solutions which, sadly, does not automatically show you a lot regarding the quality of sound. To help you make a smarter purchasing decision, I'll clarify what this spec means and the way to interpret it. This I hope will ensure you'll get the ideal wireless loudspeakers for your project. Wireless speakers are made to transmit and the reproduce a sound signal to moderate or high volume level. Suppliers usually show the frequency range over which the cordless loudspeakers operate. Generally a lower and upper frequency are provided, just like 20 Hz - 20 kHz. This specification shows that the cordless speakers can transmit and then reproduce music inside that frequency range. You may very well be tempted to pick a set ofcordless speakers that gives the largest frequency response. On the other hand, there is a lot more to understanding a cordless loudspeakers's overall performance than simply realizing this simple range.
It appears there are numerous ways that manufacturers utilize when specifying the frequency response. The most frequently used way is to describe the frequency response as the frequency range within which the wireless speakers will have quite constant sound pressure level with a maximum decrease of 3 decibel (dB). Ordinarily the drop in sound pressure level is highest at the lower and upper frequency.
A large frequency response doesn't imply the cordless loudspeakers offer excellent sound quality. For instance a set of wireless loudspeakers which has a frequency response between 30 Hz and 15 kHz may sound better than a different set with a response between 10 Hz and 30 kHz. Moreover, every producer, it appears, implements a different technique of specifying the minimum and maximum frequency of their cordless speakers. The normal convention is to display the frequency range inside of which the sound pressure level of the speakers is going to decrease no more than 3 dB from the nominal level. However, a lot of manufacturers disregard this convention. They push the lower frequency and upper frequency to where the cordless loudspeakers rarely provide any kind of sound response. On top of that, these figures say practically nothing about precisely how linear the wireless speakers are operating inside this range. Consequently it is better to have a complete frequency response chart. This sort of graph will show whether or not there are any significant peaks and / or valleys inside the operating frequency range. Peaks and valleys might cause colorization of the audio. If possible the cordless loudspeakers should have a constant sound pressure level within the whole 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 whole lot regarding the overall performance and also quality of sound of the cordless loudspeakers.
On the other hand, the frequency response often is used in order to misinform consumers by way of extending the frequency range far past the range where the wireless speakers still function correctly and also covers up the fact that the wireless speakers might not be linear. If possible you should really seek to get a frequency response diagram from the producer. In this diagram, you will discover the way the wireless speakers function inside the frequency response range. You can also discover any peaks and valleys the wireless speakers could possibly have. Peaks in addition to valleys can cause colorization of the sound. Ideally the sound pressure level of the wireless loudspeakers should be linear throughout the entire operating range.
The frequency response of Class-D amps shows the biggest change with various speaker loads because of the integrated lowpass filter which removes switching noise from the speaker amplifier's signal. The lowpass filter characteristic, on the other hand, greatly depends upon the attached speaker load.
Some amplifiers incorporate feedback to compensate for changes in gain because of different attached loads. Yet another approach utilizes audio transformers between the power stage of the amp and various outputs. Each output was designed to attach a different speaker load. This approach makes sure that the amplifier is going to be loaded equally and also increases amplifier power efficiency.
