History of the development of JBL subwoofers
Since the advent of automobile speaker systems premium class in the 70s of the last century, JBL was already actively involved in the development of converters and amplifiers for the implementation of Hi-Fi systems in cars, making the most of its rich 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 also increased. key element reproduction of high-quality sound.

JBL Car Subwoofer Technologies
Patented SSI™ 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, more high quality sound, 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 suspension rigidity at permanent basis and throughout the entire range of motion of the coil. 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 annoying background noise, created by intense air flows in the bass reflex pipe. 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.

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 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 customary on modern devices, but pressed. 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 fake JBL Charge 2 sound more open and louder than their original competitors - for example, Sound Blaster Roar. Lower and uppercase 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 quite high level volume to play heavy compositions. In detail and depth low frequencies losses occur 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 the time battery life- 12 hours of trouble-free music playback. 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 best speakers in its class and at such a price for the JBL Charge 2. The gadget has good bass, reproduces music quite well for its category at maximum volume and is equipped with capacious battery, which 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 to portable speaker any device - smartphone, tablet, player - and charge it while listening to music. This function very profitable 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 an original and unique design Charge column 2 is significantly ahead of 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.
