When purchasing a brand new set of wireless loudspeakers, you almost certainly are going to take a look at the technical specs. One often found specification is the frequency response. This spec whilst essential does not tell the full story pertaining to how good the speakers are going to sound. I will shed light on the meaning of this term and additionally provide some suggestions on how to interpret it while searching for a set of cordless loudspeakers. A set of cordless speakers are going to transmit and the reproduce an audio signal that is inside the frequency response range. This range is specified by listing 2 frequencies: a lower as well as upper frequency. As an example, the lower frequency could be 20 Hz and the upper frequency 20 kHz. Using this spec it seems the cordless speakers would be able to function as a set of HIFI loudspeakers. Then again, there is more to comprehending the wireless speakers's performance than just taking a look at these figures.
Cordless speakers are meant to transmit and the reproduce an audio signal to medium or large volume level. Manufacturers generally show the frequency range over which the cordless speakers work. Commonly a lower and upper frequency are provided, like 20 Hz - 20 kHz. This particular spec indicates that the cordless speakers are able to transmit and then reproduce audio within that frequency range. You may be thinking the greater the frequency response the better the wireless loudspeakers. That, on the other hand, will not always be the case. You have to consider the specifications a lot more meticulously to adequately understand them.
A large frequency response doesn't imply the cordless loudspeakers provide great audio quality. By way of example a set of cordless loudspeakers that has a frequency response between 30 Hz and 15 kHz may sound a lot better than a different set having a response between 10 Hz and 30 kHz. Also, every producer, it appears, uses a different way of specifying the minimum and maximum frequency of their wireless speakers. The normal convention is to present the frequency range within which the sound pressure level of the loudspeakers is going to drop a maximum of 3 dB from the nominal level.
In order to better understand the frequency response behavior of a specific model, you should attempt to determine under which circumstances the response was calculated. You might find these details in the data sheet of the cordless loudspeakers. Then again, many producers won't publish those in which case you may need to get in touch with the maker directly. One condition which can impact the frequency response is the impedance of the speaker driver built into the wireless speakers. Typical loudspeaker driver impedances vary from 2 to 16 Ohms. The lower the speaker driver impedance the greater the burden for the internal amplifier.
This change is most detectable with most cordless speakers that use digital amps, also referred to as Class-D amplifiers. Class-D amps use a lowpass filter within their output to reduce the switching components that are created by the internal power FETs. A varying speaker driver load will impact the filter response to some amount. Usually the lower the loudspeaker driver impedance the lower the highest frequency of the built-in amplifier. In addition, the linearity of the amplifier gain will be determined by the driver load.
A number of amps integrate feedback to be able to compensate for changes in gain caused by different connected loads. One more approach uses audio transformers between the power stage of the amp and several outputs. Each output was created to attach a different speaker load. This approach ensures that the amplifier will be loaded equally and also enhances amplifier power efficiency.
