GB Ale from China. Portable speakers Jbl

JBL is a company that produces 139 products for car audio and home electronics. It enjoys well-deserved recognition among professionals and lovers of high-quality audio. Every year, the line of JBL subwoofers for cars is replenished with new models, they become better, louder, larger, to which the consumer sector is sensitively reacting.

History of the development of JBL subwoofers

Since the introduction of premium car audio systems in the 1970s, JBL has been actively involved in the development of transducers and amplifiers for the implementation of Hi-Fi systems in cars, making the most of its wealth of engineering experience. Cars have changed significantly since then. Music media and customer habits have changed even further. During this process, the need for high-quality speaker systems, subwoofers and amplifiers has also increased as a key element in reproducing high-quality sound.

JBL delivers this advancement in all its glory, leveraging technologies that were designed for studio monitors, live speakers and premium home equipment.

JBL Car Subwoofer Technologies

Patented SSIā„¢ Smart Impedance technology with exclusive impedance selector allows you to have one universal subwoofer line and select the optimal impedance for your system based on the number of subwoofers you use. In addition, you will certainly appreciate the possibility of easily expanding the system in the future.

The suspension ensures reliable fastening of the diffuser even with large strokes. There are a number of reasons why JBL uses rubber and butyl rubber surrounds on all car speaker systems.

The first of these is durability. Polyurethane foam hangers degrade over time and fail under the influence of moisture, ultraviolet radiation and humidity. Rubber suspensions, in turn, are immune to these influences. The second reason is that rubber and butyl rubber surrounds provide optimal support for the cone and absorb unwanted abnormal distortion that occurs near the edge of the cone. Thus, the benefit is reduced distortion and increased playback power. Due to this, higher sound quality is achieved, clear and loud sound reproduction at low and medium frequencies without any destructive effect on the suspensions.

All JBL subwoofers are designed to operate over a wide range of cone displacement, and there is no way to do without centering washers with a progressive stiffness characteristic. This centering washer maintains the rigidity of the suspension on a constant basis and throughout the entire range of motion of the reel. The greater the amplitude of movement of the coil, the higher the efficiency of its operation!

Without this level of control, the cone can warp, resulting in unwanted distortion at high power.

JBL cabinet subwoofers

The patented Slipstream bass reflex in JBL enclosed subwoofers eliminates the annoying background noise created by intense air currents in the bass reflex tube. Compared to conventional bass reflex ports, the key advantage of Slipstream's patented technology is the ability to realize higher volumes and eliminate distortion. This makes your system sound louder and deliver clearer bass.

Models in the JBL line of portable speakers provide a wireless Bluetooth connection to a mobile device, which allows you to listen to music loudly directly from the gadget. Due to the use of high-quality materials in the manufacture of the elemental base of the portable speaker, the acoustics reproduce clear sound.

One of the most popular brands of audio equipment in world markets is the JBL brand, created in 1946 and owned by the Harman International concern.

The JBL Charge 2 portable speaker only comes with a power supply, replacement plugs and instruction manual. No additional accessories are implied.

Charge 2 design

The appearance of Charge 2 is practically no different from the previous model and is focused only on mobile and general use. The original JBL Charge 2 looks like a cylinder, making it easy to attach, for example, to a bicycle frame using a standard holder.

The large battery had a negative impact on the weight of the speaker: it exceeded half a kilogram. Perhaps this characteristic of the JBL Charge 2 is the only one that can cause inconvenience to the user.

The body is mostly made of rubberized plastic. One of the distinctive characteristics of JBL Charge 2 is the thoughtful shape of the case, in which the speakers are covered with plastic grilles recessed into the base material. The full-range speakers are located on the manufacturer's logo side, while the second grille is installed only for symmetry in the design.

The grilles are separated at the top by a control panel equipped with backlit keys. The buttons are not touch-sensitive, as is common on modern devices, but pressable. This characteristic of JBL Cherge 2, such as the absence of protruding parts, is a good advantage, especially if the acoustics are used in extreme conditions. You can distinguish the buttons tactilely, blindly, the volume swings are embossed. Next to the tube there is a small hole - a microphone.

Passive radiators are located at the ends of the column. They are not protected by anything, but at the same time they are recessed quite deeply into the body, due to which, as users especially note in their reviews of the JBL Charge 2, there is no impact on them. During operation, the emitters vibrate quite noticeably.

On the right side of the case there are small legs that allow you to install the speaker in a vertical position. In the JBL Charge 2 acoustics, a distinguishing characteristic is a special indicator located under the volume buttons.

Under the grille located on the back of the speaker, three connectors are hidden: for charging third-party devices - a high-ampere USB input, for connecting sound sources - TRS 3.5 mm, and for charging a gadget - microUSB.

Due to the elongated base, the column does not have sufficient stability, which is why it easily tips over. Despite this, in the reviews, users note that this does not threaten the acoustics, since after several swings its speakers remain pointed upward.

Column measurements

Many users in their reviews conducted various tests of the characteristics of JBL Charge 2. For this class of acoustics, the uniformity of the frequency response graph is acceptable in the intervals from 75 Hz and 2 kHz and from 5 kHz to 12 kHz. It is worth noting separately that the graph reaches an acceptable level quite early.

The maximum sound pressure, which is often measured by specialists, is one of the important parameters of acoustic systems. The test is simple: the speaker is placed on a chipboard table so that the main speakers are directed towards the measuring microphone. A measuring microphone is mounted at a distance of a meter at the same height and connected to a spectrum analyzer.

Synchronizes with a smartphone with the maximum volume level set. During the test, average dBA readings are recorded for half a minute of sound in any so-called pink noise player.

Based on the results of the tests, we can say that the JBL Charge 2 portable acoustics are practically not inferior to their analogues in sound quality and volume.

Sound

JBL speakers have excellent sound quality: even the JBL Charge 2 fakes have a more open and loud sound than their original competitors - for example, the Sound Blaster Roar. The lower and upper registers are more detailed, which allows you to convey the nuances of the sound of various musical instruments.

The instructions for JBL Charge 2 note such a function as simultaneous synchronization of up to three third-party devices. The gadget that was connected first remains priority: the rest do not join until playback on it is completed. When you press the corresponding key, priority is transferred to the device that is currently connected to the speaker.

The disadvantage of the JBL speaker as a wireless headset is the reduced sensitivity of the microphone: in order for the interlocutor to hear anything, you need to move close to the speaker. Despite the fact that the maximum volume is low, the timbre of the voice is transmitted without any distortion.

The maximum volume level is enough to sound a room of 20 square meters. At a volume of 50-70%, the JBL speaker copes well with any genres and compositions, delighting listeners with clear high notes, detailed bass and a good midrange. This gadget is ideal for both background sound and for creating a working atmosphere.

JBL Charge 2 is perhaps the first speaker on the acoustics market capable of playing heavy compositions at fairly high volume levels. Loss in detail and depth of low frequencies occurs only at maximum volume. Despite its compact size, the speaker clearly and accurately reproduces many genres of music. Controversial compositions are best played at medium volume levels.

Separately, it is worth mentioning such a feature of Charge 2 as fast connection via Bluetooth - a pair is created in almost a second, while analogues require five to seven seconds to connect. The JBL Charge 2 instructions indicate a battery life of 12 hours, during which trouble-free music playback is carried out. The mentioned time can be reduced several times if the portable acoustics are used as a charger for a tablet or smartphone.

The acoustics from Harman were not just improved by the manufacturer, but completely redesigned, which made it possible to create one of the best speakers in its class and at this price for the JBL Charge 2. The gadget has good bass, reproduces music quite well for its category at maximum volume level and is equipped with a capacious battery that allows you to charge third-party devices. The average price of JBL Charge 2 is 7 thousand rubles.

Autonomous operation of the column

At an average volume level when connected to a tablet, the JBL speaker can work for 18 hours, after which the battery is completely discharged. A large, high-power battery allows JBL Charge 2 to show good battery life results in comparison with similar devices of the same price category, being slightly inferior in this indicator to some other portable speaker systems.

Connection options

You can synchronize the JBL Charge 2 portable speaker with any devices and gadgets via a Bluetooth connection or using a 3.5 mm cable. Unfortunately, such a cable is not included in the kit; it will have to be purchased separately. The Bluetooth 3.0 profile is used for connection - a high-speed, high-quality connection.

Distinctive features of acoustics

As mentioned above, the main feature of JBL Charge 2 is the mentioned Social Mode, that is, the ability to charge third-party gadgets. Using a standard USB cable, you can connect any device - smartphone, tablet, player - to the portable speaker and charge it while listening to music. This function is very beneficial and useful and will serve well in situations where it is difficult to access the network to fully charge the gadget.

Review results

Throughout all the years of its existence, portable acoustics from the JBL brand have made a good impression on users, impressing with their quality and excellent sound. Together with its original and unique design, the Charge 2 speaker significantly outperforms its main competitors in the same class and price category. The ability to charge third-party devices can help the user out when traveling or long walks, as has been repeatedly noted in numerous reviews of the JBL Charge 2. The cost of the Charge 2 with such a set of functions and characteristics does not look so high: the speaker can easily compete with expensive products from famous brands. brands, bypassing many of them.
