Q B2 Bluetooth HIFI desktop speakers
In the minds of many HIFI zealot, wireless connectivity and voice is a friend, speaker products using wireless connections are also hard to burn the friends be interested on the market most of the speakers are wireless Bluetooth connection is taking the low end of the line, and as for the sound you know. With the progress of science and technology in recent years, wireless connection to Bluetooth technology have enjoyed great development, new audio codec based on Bluetooth 4.0 aptX, finally can meet the need of high-quality wireless audio transmission. This breakthrough has attracted many professional audio manufacturers, to test the water of high quality wireless Bluetooth speaker products. However, such as B&W, and B&O, JBL most of these products are personalized appearance, while price and sound didn't have much appeal. From the United States in a professional listening device origin sound engine sound, its a wireless Bluetooth stereo model B2 is particularly attractive. This amp has the elegance of traditional HIFI-style appearance, elegant and lustrous vocal performance, compared to the average price of 1799 and similar products is also in good faith.
Q products mainly include: active speaker system, and USB decoder, not speakers, power amplifiers, subwoofers, passive audio transmitter, and its compact desktop speaker system is much-respected HIFI ring friends. These small speakers affordable, superior quality, and can be placed on your desktop computer or digital device connections. The B2 in particular is very unique and eye-catching, it placed left and right channels with four speakers in a speaker, two-channel independent of each other, from the outside looks like a center-channel speaker for home theater. For a focus on sound quality of audio manufacturers, in order to make B2 get better wireless Bluetooth transmission, with aptX Bluetooth audio coding technology, can provide higher quality than the previous version voice of near-lossless, and backward compatible with all Bluetooth version, external antenna, together with the Bluetooth transmission distance was extended to 25-30 m.
B2 from the parameter using the hardware configuration, and another q-box A2+ of the heat is the same, use class AB power amplifier using the traditional analog circuit design. High quality TI PCM5102A DAC Digital to analog converter, has the characteristic of low noise, and high fidelity, you can fill all bit depths into 24-bit, in order to achieve a higher signal to noise ratio. Triple voltage regulator filter in the power section, together with the B2, low noise and low distortion characteristics which cannot be denied, most Bluetooth speaker.
Hand-made wooden box is texture, whether Visual or tactile HIFI with a deep flavor. Quality process not only for the beautiful, of course, 18mm thick MDF with solid wood laminate Cabinet, coupled with the strengthening of internal support can be effective in reducing unnecessary distortion and resonant. Box edge deliberately polished into rounded corners, in order to reduce sound diffraction from tweeter in the front panel. In order to prevent crosstalk, the B2 Cabinet adopted the internal two-channel independent of the complex design, front-hole on both sides of the box have been separate debug, so thorough about a HIFI only to your heart.
Q B2 prepared a total of black ash, walnut, Zebra wood, texture of three different styles, and I hand this is Walnut color, I don't think its color depth for the environment will be more broad. Although solid wood veneer, but under rigorous q-outstanding technology, also has excellent texture like solid wood. Whether Visual stimuli, is touching the touch, are extremely beautiful.
Q B2 body dimensions: 4.25 in (long) x12.25 ″ (wide) X5.50 in (h), weight: 4.21 kg. Such experiences are a lot larger than the portable speaker, but compared with the traditional 2.0 speaker has obvious advantages, also eliminates the excess wire connections, you can easily move around at home.
Box for the detail design is also quite research, in order to reduce unnecessary distortion and resonant, speaker set internally to strengthen the support, filled with a high-intensity sound-absorbing material to reduce unnecessary sound reflections inside. Cabinet edges and delicate, round corners, not only for aesthetic reasons, and in order to reduce sound diffraction from tweeter in the front panel.
Appearance from the B2 looks like the center-channel speaker for home theater, but in the B2 internal and center-channel speaker is very different. Within the design of two-channel fully independent, has a high, bass speaker for each channel. Outside design orientation in favour of sound and treble, phase hole easier front speaker placement.
Q-power amplifiers do not use small speaker pop of class-d amplifiers, in order to guarantee access to the driver, but instead of using the traditional analogue class AB amplifier, two-channel 30W power rating is enough to feed B2. 20mm tweeter with neodymium magnet wire film, this small volume, light weight, magnetic flux can bring more richness of detail, also has a good degree of resistance.
Low frequency use sunken installation method, edges the same after fine grinding, speakers everywhere reveal a sense of refinement. 2.75-inch Kevlar Woofer, use of non-woven glass aramid composite, light also bends under a beautiful spot, sound can render a full and fast bass.
Speaker mesh to protect the speaker function, can effectively resist dust penetration. B2 uses the speaker mesh cover using magnetic attraction, removal and installation is very easy, so that speakers are free to head on opening. However q-B2 match the grey cover, pack up but looks a bit dull, remove immediately after giving the sense of a large. For many enthusiastic fan, we all prefer professional style ~ without a net.
Q B2 attracted me most places, an elegant appearance, the other is for high-quality wireless Bluetooth transmission. Carries the aptX is an advanced Bluetooth audio coding technology, than previous versions can provide a higher quality of sound levels can provide near CD sound quality, while version backward compatible with all Bluetooth A2DP and AVRCP. However, aptX also has certain requirements for wireless front-end, as long as it's nearly two years in the Bluetooth 4.0 launching high-end mobile phones, basically can support the aptX audio coding technology.
Speakers exposed above and below surface in front of us is very neat, full solid wood elegant and delicate texture is passed out, as if the art is not defective. All affect the appearance of the connections with the function keys are set in the back of the speaker, but even the back of the block function is also very neat. B2 is not used nowadays many Bluetooth speaker support SD card read, USB playback and other fancy features, in addition to high quality Bluetooth transmission is only AUX audio input, and it is also in keeping with its lofty qualities. But what makes me uncomfortable is Bluetooth and AUX audio input is not switched, if you use two ways to play music, two kinds of music will meet together at the same time came out of speakers, to be able to add a Bluetooth AUX sound source switch function will be more perfect.
Installation of the amplifier Board is also very particular about the basically level with the wood edge-preserving. 30W power rating is not large, so speakers also provided no additional radiator, only feel the heat a long time, but the temperature is not too high. Rear power cable connectors and the power switch is set to the right, repeatedly held their logo on a does not affect the appearance of the place.
Main functional areas in the left side of the rear of the speaker, silver metal volume knob is very delicate, and rotation damping is very smooth and delicate. Below it is 3.5mm AUX audio input port, and Bluetooth connections. On the volume knob on the right is the Bluetooth pairing button, white light, President of the press after a successful pairing, such as the need for pairing again you can long press this building until white light starts blinking after pairing. To enable the Bluetooth signal to greater distances, B2 designed a similar antenna and a wireless router, and made only 10 meters of distance, extended to 25-30 meters, there is a wall in the home of the barrier will not affect the stability of Bluetooth signals and adjustment of the antenna can make different perspectives.
And ordinary Bluetooth devices the Bluetooth connection process is the same, the Bluetooth receiving first phone or Tablet feature is turned on, open and match the B2 is in a wait state, when you search for "Audioengine B2" click when you can complete the pairing.
General Bluetooth speaker 10 metres distance, out the door could signal the actual environment in the home will be intermittent connections. B2 has a strong antenna, at home in a wall without a problem isolation, so that the signal is always very stable. Good aptX can get more near-lossless audio coding high quality audio transmission, while high-quality TI PCM5102A DAC Digital to analog converter, together with the B2 with the AUX cable and Bluetooth wireless music listening experience will not be much change, the sound quality is far higher than the General Bluetooth speaker.
Another very obvious feelings is low latency, had also used a number of Bluetooth speakers, listen to music, watch movies can feel a little delay, sound a little bit more slowly than in the picture. B2 aptX audio coding technology, which only 30 Ms delay, reached the level of difficult to perceive, watch violent movies are properly completed ~.
Believe see here about q-B2 of the sleek look and rationalization of the functions are very accepted, but as a speaker more important are the playback performance. B2 uses a similar box and center-channel speaker for home theater, but its interior is to separate the left and right channel independent, this structure is more suitable for near field listening, and treble outside design or you can get a better sense of orientation.
Duo cone cells smaller, more suitable for desktop listening environment. 20mm films soprano brings a wealth of detail and has a good degree of resistance, and 2.75-inch Kevlar Woofer can render a full and fast bass. After a period of time, nearly 50 hours of use, B2 's voice getting better gradually stabilized, it seems appropriate to burn is still very necessary. I tried using Regulus iipro HD audio A-e amp + pure flute as a front end, with connected through AUX, and wireless Bluetooth connectivity with voice effect. Desktop front end in momentum, sound density, compared to the overall dynamic control of Bluetooth is of great advantage. Bluetooth and the difference between a massive class gap wasn't, TI PCM5102A DAC with the help of Bluetooth transmissions can be received more ethereal sound, more transparent sound textures, parsing is slightly higher this is my surprise, q-B2 is the voice I heard the best Bluetooth speaker.
My hands vivo xhsot, VIVO x5max, iPad mini2 several product support aptX, repeated listening using these devices, have shown a high degree of stability, and there were no common Bluetooth speaker sometimes sonic phenomena. Bluetooth mode is used below to listen and share with you a simple sense. B2 's sound just slightly sweet and the neutral line, tri-band connection is natural, wine is not thick, presenting a fresh and slightly dense texture. Because the left tweeter distance is not very open, in listening distance of 60~120cm sound field in a certain location, but does not have any strong levels is not very open. High frequency soft and delicate, extension is also good, rich in detail; if the set-up is brilliant, warm and good overall sense of density, vocals stand out, whether it is male or female has a positive performance. Subject to a 2.75-inch woofer size, low frequency limit for 65Hz is doomed to not be much low frequency output, but the texture is very good, speed has some meat. Using medium and small volume when near-field listening very good sound effect can be obtained, if the sound is too large can seem confusing. Overall sound of q-B2 characteristics more suitable for vocal, jazz, little preparation of instrumental music.

Summary | |
As a regular professional players will touch the new fun products, few have attracted my attention at once, but q-let me love at first sight. I like its elegance of the traditional HIFI-style appearance, combined with solid wood texture of the box can be well integrated into the different home environments. Sound set-up and internal circuit design also show q professional and serious attitude, elegant and lustrous sound has a high degree of resistance. AptX Bluetooth transmission and high quality, you can get very good sound reduction, while gain antenna with the Bluetooth coverage greatly expanded. The only inadequacy is that the AUX audio input and Bluetooth switch is not set, two audio sources can simultaneously access speakers, which makes me feel a little uncomfortable, B2 I really satisfied with others. Average price of 1799 is not cheap, but compared with products at the same level B2 is a product in good faith.
