How to solve the low-frequency problem of bookshelf boxes? Tesla Definiti in the audio industry is a recognized expert

The most hesitant thing for many consumers who are interested in incorporating bookshelf boxes into their speaker listening combinations is that although bookshelf boxes have very flexible use flexibility, they also have a certain degree of flexibility in mid- and high-frequency reproduction. , but not good at mid-bass and bass, which is also a major market pain point for this category of products. In order to solve this problem, major audio brands have come up with their own strategies, striving to make the low-frequency performance of bookshelf boxes richer. In this regard, the American company D.T., known as the "Tesla" of the audio industry, also has its own ingenious solution.

So far, D11 is one of the three models in the DEMAND series launched by Definiti, and it is the one with the largest size and best low-frequency effect - the other two are D9 and D7. Let’s first take a look at the unit configuration and cabinet condition of D11. In the treble part, this bookshelf box uses a 1-inch porcelain/aluminum composite treble diaphragm. In the mid-low frequency section, it uses a polypropylene composite diaphragm, which has very good rigidity.

In the field of imaging, many brands have hierarchical product technology applications, but Definiti insists on using the best technology in all its products, including patented balanced double-folding rings ( BDSS) unit, patented linear response waveguide phase plug, porcelain-aluminum composite dome tweeter, and high-quality passive bass unit.

As the leading model of the entire DEMAND series, D11 has the largest size and power, and is also the most comprehensive high-end bookshelf box. It combines high-performance bookshelf speaker design with an elegant and stylish appearance. D11 can completely reproduce the sound effects in the full frequency range, and at the same time, it has precise restoration power. Due to the use of treble deflection technology, it can provide a very wide listening position, while combining with the passive bass radiator built into each speaker to present deep low-frequency sound effects. If the listener chooses to match the D11 with a special tripod, its inherent advantages can be easily brought into play.

D11 can easily display a full, dense, and lively sound overall. Its high frequency has unexpectedly soft characteristics, is full of luster, has a noble and elegant taste, and at the same time has extremely rich detail display capabilities and abundant analytical power, which is exactly the kind of dense and delicate brought by bookshelf boxes. The sense of hearing is difficult to hear on many aluminum alloy dome tweeters. This brand is indeed very skillful in adjusting the sound. When D11 is playing back, it is easy to fill the entire frequency band with the body and high density of the sound, with sufficient volume and huge amount of information, which completely gives a sense of satisfaction that wraps people up. The main reason is naturally the very wide coverage frequency band of the D11 mid-range unit. This mid-range unit covers part of the lower high-frequency area upwards, achieving dense and smooth high frequencies; and covers the low-frequency areas downwards. The upper area ensures the natural connection between the two.

The most distinctive point is that, with the help of the passive radiation woofer unit on the top of the cabinet, D11 has a good sense of connection within the upper limit of the mid-low frequency and low frequency bands, and with At the same time, the dynamics and depth of mid-low frequencies also have good overall control capabilities. It can achieve better and more solid sound effects than ordinary bookshelf boxes.

As a brand with a short history, and coming from the United States, Definiti seems to be a new brand in the eyes of many seasoned brands. But in fact, the rapid growth of this brand and becoming the leader in the North American market is precisely the result of their team's work.

The founder of Definiti is a senior audio enthusiast and a film producer. He initially felt that there was still room for success in the high-end market of cinema systems, so he quickly attracted him. A group of engineers, designers, and musicians with professional backgrounds, such as Don Givogue and Ed Blais, have always maintained this inclusive concept of recruiting talents. This is why today's vibrant Difennity is born, and it is naturally also known as Dubbed the "Tesla of the audio industry".
