JBL Studio 2 and JBL Arena customizable speakers

24.10.2015

Especially for demanding music lovers, Harman International Industries has developed high-level acoustic systems JBL Studio 2 and JBL Arena architectural series. New items combine impeccable (according to the manufacturer) design with the best sound quality in its class. The speakers are designed to be built into walls or ceilings and complement Harman's existing JBL Studio 2 and JBL Arena families.

Powered by JBL High Definition Imaging (HDI) Waveguide technology, the speakers deliver a realistic soundstage that can be enjoyed at every point in the room. XL-2 mounts are available for speaker mounting. In this case, the thickness of the wall can be less than five centimeters. A special clamp minimizes vibrations generated during operation.

Studio 2 models include aluminum composite tweeters and PolyPlas basses. Depending on the preferences of users and the acoustic characteristics of the room, compensation is provided within 3 dB.

The cost of new products - from $175 to $350.

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Major risk factor for gambling addiction 07.05.2024

Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

inflatable tablets 01.02.2019

Scientists have developed a jelly-like pill that inflates to the size of a ping-pong ball when it enters the stomach. Such tablets can be used to monitor tumors or ulcers. The device was inspired by the puffer fish, or puffer fish, which can quickly inflate when it feels threatened.

The MIT team behind the invention claims the pill can last up to a month in the body. The innovation has already been tested on pigs.

The tablet was made from two types of hydrogel: the inner layer consists of absorbent particles, and the outer one with a protective membrane. This gives the invention a jelly-like consistency, helps it rapidly increase in size in the stomach and thus prevents it from leaving the body.

The inflatable tablet can be removed from the body at any time by drinking a calcium solution. This will help her quickly shrink back to her original size. The new tablet is softer and lasts longer than alternatives, which are often made of hard plastic or metal.
