A retrospective
Dutch & Dutch
Model: 8C
The positioning of the Dutch & Dutch 8C is different from most similar products, it is enthusiast positioning, aimed at the younger generation of enthusiasts. And the configuration is also very fierce,8C is a three-way design,Among them,The tweeter is1-inch aluminum-magnesium alloy hemispherical tweeter,Just such a small tweeter is actually equipped with250W power amplifier! The mid-bass is an 8-inch aluminum mid-woofer, which is also equipped with a 250W output power amplifier, and the two subwoofers on the back are also 8-inch aluminum subwoofers, responsible for sound playback at frequencies below 100Hz. It can be seen that the folding rings of these two units are particularly thick, and the stroke is also long, and then these two subwoofers are equipped with 500W power amplifiers, and the maximum total power of each speaker is 1000W! As for the built-in power amplifier, the Class D power amplifier module from Pascal in Denmark is used. In fact, such a configuration,In the home environment, it is completely over-specified,It can be called the "heavy gunner" in the bookshelf speaker。
The 8C is designed with directional control, and the control range of sound transmission is more than 100Hz. For the high-frequency part, the method is relatively simple, the 8C uses a waveguide to control the directivity of the high frequencies, and this waveguide can also extend the lower replay limit of the tweeter to connect it to the 8-inch mid-woofer, and the crossover point between the two is 1.25kHz. As for the mid-low frequency part,We pay attention to the opening on each side of the speaker,This opening is to draw out the backwave of the mid-woofer (inverting sound) to cancel out the sound diffracted to both sides of the speaker,So as to control the directivity,And 8The lower replay limit of the mid-woofer is set to100Hz,The purpose is to get more direct sound,Suitable for studio monitoring,Also suitable for home environment。
8C uses an App called Ascend to control, not only to control the volume, switch inputs, but also with a high-performance PEQ function, which can correct the frequency response according to the characteristics of the room, as for the digital streaming part, 8C supports Roon Ready, through the Roon software can achieve powerful network streaming music playback, but also allows users to better manage their own music.
Bang & Olufsen
Model: Beolab 90
The Beolab 90 is Bang & Olufsen's HI-END rated web-streaming speaker, launched by Bang & Olufsen for its 90th anniversary. Compared with traditional HI-END loudspeakers, Beolab 90 is aimed at the wealthy who pursue fashion, industrial design, and sound quality. Beolab 90 was designed by Frackenpohl Poulheim, a well-known design studio in Germany.
Beolab 90 is very exaggerated in terms of sound configuration, 18 units are installed in one speaker, including 7 1-inch tweeters, 7 4.5-inch midrange drivers, 3 10-inch woofers, and 1 13-inch subwoofer, all of which are from Denmark Scan-Speake products. And each unit is assigned an amplifier. Among them, the treble section and the midrange section each have 7 Bang & Olufsen ICEPower AM300-X amplifiers, each with an output power of 300W. The bass and subwoofer sections are each home to 3 Heliox AM1000-1 amplifiers and 1 Heliox AM1000-1 amplifier, each with an output of 1000W, for a total power of 8400W for just one speaker! It can provide a steady stream of power.
To give the user the best possible sound, Beolab 90 comes with Active Room Compensation, Beam Width Control and Beam Direction Control. Room Acoustic Compensation compensates for the acoustic characteristics of the listening position to improve the sound. The sound wave width control function can change the sound field width, and the sound wave direction control can control the sound direction, which can be optimized for 5 points in the listening area.
In terms of audio access, Beolab 90 is available in both analog and digital formats, with unbalanced (RCA) and balanced (XLR) for analogue, optical and coaxial for digital, and USB Audio, which can support a wide range of audio source devices. When it comes to streaming music online, Beolab 90 uses the Bang & Olufsen App, which allows you to stream online radio stations and TIDAL streaming music. In terms of the applicable environment, Bang & Olufsen recommends that Beolab 90 be suitable for 30~200 square meters. It also offers three styles of appearance for consumers to choose from.
