Materials And Construction
0.7″ (18 mm) thick MDF cabinets with real wood veneer
0.75″ (20 mm) silk dome tweeters with neodymium magnets
2.75″ (70 mm) aramid fiber woofers with advanced voice coils
To minimize unwanted resonances and distortion, Audioengine cabinets have thick high-resin MDF walls with extensive internal bracing. Heavy internal sound-damping material is also used to reduce unwanted sound reflections inside the cabinet. The B2 cabinet is a unique design in that it has dual sub-enclosures to prevent cross-interference, while each side contains its own tuned, front-port bass slot.
Furniture Grade Finishes
The B2 cabinet is available in several handsome finishes, including walnut and zebrawood veneers as well as satin black paint, offering a wide choice for complementing room furnishings. Also included is a detachable grill that adds further aesthetic advantages as it’s firmly held in place with hidden neodymium magnets for a clean look.
Audioengine designs and manufactures our own tweeters, woofers, and other critical components. In other words, these are not “box built” speakers with off-the-shelf parts but custom-designed to our specifications. What we do not fabricate directly in our factory we have made to our designs (parts such as transformers, magnets, and wiring harnesses, for example). The cabinets, drivers, bass port designs, amplifiers, and crossovers are all painstakingly tuned together for each Audioengine model. This, in turn, makes for a much more efficient system that requires much less power than passive speakers and a separate integrated amplifier or similar A/V components.
Based On Studio Monitor Designs
Studio monitor speakers are used by producers and engineers in recording and production studios. They are designed with a theoretical flat frequency response which allows the engineer to create a final mix in such a way that the recorded music will sound good on most other speakers. Although Audioengine speakers are not designed to be up-close “nearfield” studio monitors, we do carry over much of the same higher-end technology, components, and design philosophy for all Audioengine speaker systems.
High-quality Bluetooth Audio
The Bluetooth built into the B2 Wireless speakers features aptX coding which is an advanced Bluetooth audio codec with very impressive sound. And even if your phone or tablet does not have aptX, the B2 Wireless Bluetooth solution is backwards-compatible with SBC and AAC codecs, so you can wirelessly stream music from any Bluetooth-enabled device and still enjoy all your music. High-fidelity Bluetooth aptX that really works and sounds great.
Most Bluetooth implementations have very limited range, typically within just one room. But with careful signal management circuitry and antenna tuning, we offer a superior solution that has up to 3 times the range of standard Bluetooth for multi-room use, with no degradation in audio quality..

24 bit DAC
The B2 Bluetooth receiver and USB input both utilize the PCM 5102 DAC, widely known for its low-noise and high-fidelity. The PCM 5102 is used as an upsampling DAC and will pad all bit depths to 24 bit, achieving a higher signal-to-noise ratio and lower noise floor. Due to the high signal-to-noise specs of the PCM 5102, the fact that digital signal is upsampled to 24 bit as well as the added benefit of onboard triple redundancy power source conversion and filtering the B2 Bluetooth implementation presents impressive low noise and low distortion characteristics with a noticeable improvement over other Bluetooth devices.
The class A/B amplifiers in Audioengine speaker systems are very conservatively-rated analog designs. Each subsystem is tuned together for all models, providing a much more efficient system requiring less power than passive speakers and separate amplifiers. An auto-standby idle mode is also included to conserve power when you’re not playing music.
Audioengine uses audiophile-quality, ferrofluid-cooled, silk dome tweeters with neodymium magnets. Silk tweeters hold up well under high power and the edge-driven design gives very smooth response. The custom woofers are aramid fiber woven glass composite with rubber surrounds. Aramid fiber is obviously very strong, which means that the woofer retains its shape when being driven at high levels. The speaker materials and construction are very robust, therefore speaker grills aren’t needed. In other words, we did our homework on the speaker drivers and they will sound and look great after many years of use.
Both drivers are directly video shielded and allow the user to place the speakers within a few inches of a video monitor. This shielding also offers protection for hard-drive digital music players.
