Review on Portable Acoustics JBL Charge 4, 30W, grey by Gabriela Zawada ᠌

Superb sound quality. My assessment after listening to it a few times in various stores is that the lows and mids are pretty good, but the high frequencies are lacking. In actuality, the sound quality was excellent. The high frequencies are quite clear, the violin and guitar can both be heard, and everything sounds juicy and natural despite only having one speaker that covers the entire frequency spectrum (I added high ones on the equalizer for myself). The speaker has a huge magnet and a powerful coil (they consume these 30 W), the diffuser hangs on a large, very long-stroke suspension, shaking the air inside the speaker, and it also moves two side passive dynamics, which have silicone suspensions, are silicone suspensions, and are very easy to move and also have long travel. The conversation regarding bass and lows is unrelated to this one. 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 - this does not make much sense; however, if the speaker is placed against a wall, or even better on the floor of a small room, then an incredible resonance comes from its three emitters, the bass drops to 20Hz and below, and this sound no longer comes from the speaker, but rather from the walls, as this is a reflected sound; (this is what resonance is for). I was able to get a great subwoofer and hear all the subtleties in the music's low end by turning on the bass boost in jetaudio. It was simply incredible. I can hear the bottoms from the drama, a long, sluggish bass at a frequency of 30 hertz, even though I am at the other end of the flat. This crumb took me by surprise in a way I hadn't anticipated. According to my understanding, it also performs numerous tasks programmatically. If you experiment with the bass, you'll discover that once I prodded jetaudio, the column itself equalizes something. Even movie scenes can have depth and strong bottoms because the electronic brain is continually stirring something up. As the internal processing power is adequate to produce high-quality music, aptX is not included because it is not necessary. The monophonic sound was changed into something more akin to stereo by adding some echo to the mix. Throughout the full day, between 30 and 50 percent of the charge is adequate at volume.
