Buying guide for the latest Bluetooth speakers in 2022

At present, bluetooth speakers are basically designed with passive radiators, abbreviated as PR. PR can enhance the low frequency performance of speakers to a certain extent. But PR is not entirely without its drawbacks. The shortcomings of PR are easily reflected in the frequency response curve. The passive radiator design can play a similar effect to the inverted cabinet when the low frequency is attenuated at the beginning, and the low frequency will be attenuated later than the closed cabinet. However, at lower frequencies, the low-frequency energy of passive radiators decays dramatically, even faster than in an inverting design. But why almost all brands of bluetooth speakers use passive radiator design? Because of the small size of the speaker, if you don't even need PR, it won't even be cool for a while.
Since all the units of the Bluetooth speaker are all on one box, and usually the size of the Bluetooth speaker itself is not large. So even a stereo Bluetooth speaker, in fact, as long as you listen to the sound from a certain distance, it is actually a mono. (Unless there are some sound source width expansion algorithms, but it doesn't actually make much sense for the use of Bluetooth speakers)
The stereo design is more to avoid the trouble of monophonic remixing of stereo source output. And there are times when dual speakers have more power than a single speaker. In other words, a small speaker of the same size, with two small speakers installed on the structure, may generate a maximum sound pressure level that is greater than that of a single unit that can be plugged in the same box. However, this is not necessarily the case, for example, the JBL Flip5 is designed to be mono. Some people complained before that the cancellation of the stereo is shrinking. In fact, the stereo of such a small-sized speaker is not meaningful. If it is designed to be mono, it can increase the dynamic performance, it is more pragmatic.

The difference between Bluetooth speakers and traditional speakers such as HiFi speakers
The tuning and directivity of Bluetooth speakers are usually different from traditional HiFi speakers, mainly due to the different use environments and uses of the two.
If it is a HiFi speaker or monitor speaker, too much low frequency or high frequency is usually not good. But for Bluetooth speakers, more low frequency or high frequency can not be said to be bad, or sometimes there must be more low frequency. Because the low frequency mentioned here is usually tested in an anechoic room, a speaker with a flat frequency response will have a certain room gain in the low frequency of the room, and the sound we hear at this time is relatively balanced. However, if such a speaker is brought outdoors or in an open area, the low frequency may sound too low. It also makes a difference whether the speakers are placed on the table or not. This still ignores the background noise factor of a noisy environment. Some outdoor players, such as cycling enthusiasts, usually put the Bluetooth speaker in the position of the bicycle water cup. If there are other cars or environmental noise when riding outdoors, if the low frequency of the Bluetooth speaker remains flat, it may be affected by the ambient noise. mask out. For another example, the low frequency of the car audio is also higher in the room than the traditional speaker, preventing the low frequency from being masked by road noise and driving noise.

Battery life and speaker power/dynamic balance
We all know that the higher the power and dynamic range of the speaker under the same sound quality, the better. Unless the volume is loud enough, for small-sized speakers such as Bluetooth speakers, the maximum volume and dynamic performance are usually not as good as traditional speakers. That is to say, the power design of the Bluetooth speaker should be as large as possible. However, it is not. Because this premise does not consider battery life. However, as a portable Bluetooth speaker, it is usually equipped with a battery and has the need for mobile use.
