Review on Portable Acoustics JBL Charge 4, 30W, grey by Anastazja Frelek (Ma ᠌

Amazing sound. I listened to it several times in stores, it seemed that the high frequencies were so-so, and the bottoms were booming. In fact, the sound was perfect. Despite one single full-range speaker, the high frequencies are very clear, you can listen to both the violin and the guitar, everything sounds juicy and natural (I added high ones on the equalizer for myself). Bass and lows are a separate conversation, this is not a speaker, but a real good subwoofer: the speaker has a huge magnet and a powerful coil (they eat these 30 W), the diffuser hangs on a large, very long-stroke suspension, shaking the air inside the speaker, it also moves two side passive dynamics, they have silicone suspensions and they are very easy to move and also long-travel. If the speaker is in an open space, then the bass is quite similar to the declared 60 Hz, the side diffusers twitch a lot - there is not much sense from this, but if it is placed against a wall, or even better on the floor of a small room, then an incredible resonance comes from its 3 emitters , the bass drops to 20Hz and below, and this sound no longer comes from the speaker, but from the walls, this is a reflected sound (this is what resonance is for). By turning on the bass boost in jetaudio, I got an incredible subwoofer and felt all the subtleties of the bottom in my music, just fantastic. At 30% volume, even at the other end of the apartment I hear the bottoms from the drama, a long slow bass at 30 hertz. I didn’t expect this from this crumb. As I understand it, it also does a lot programmatically, if you experiment with basses, it is noticeable that the column itself equalizes something after I poked jetaudio, the electronic brain constantly stirs up something, so even scenes in films acquire depth and powerful bottoms. aptX is not here, it is not needed, the built-in brains are enough to create high-quality sound. I fixed the mono sound by adding a little echo, the sound became spatial like from stereo. At volume, 30-50% of the charge is enough for the whole day.
