MATERIALS AND CONSTRUCTION |
0.7″ (18 mm) thick MDF cabinets 0.75″ (20 mm) silk dome tweeters with neodymium magnets 2.75″ (70 mm) aramid fiber woofers with advanced voice coils |
CABINETS | To minimize unwanted resonances and distortion, Audioengine cabinets have thick high-resin MDF walls with extensive internal bracing. Heavy internal sound-damping material is used to reduce unwanted sound reflections inside the cabinet. All cabinet edges are rounded which look great and reduce high-frequency diffraction effects on the front baffles. The P4 cabinet contains tuned, front-port slots. |
FURNITURE GRADE FINISHES | The A2+ cabinets are available in several handsome, high-gloss finishes, including black, white and red paint, offering a modern compliment to any small space or desktop. |
CUSTOM COMPONENTS | 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. |
EFFICIENT INTEGRATED DESIGN | The speaker cabinets, drivers, innovative bass port designs, amplifiers, and passive crossovers are all critically tuned together for each Audioengine model. This, in turn, makes for a much more efficient system that requires less power than passive speakers and a separate integrated amplifier or similar A/V components. We build all this goodness into the left speaker cabinet to make it super-easy to connect your smartphone, tablet, computer, TV, network player or any other audio product. |
HIGH-QUALITY BLUETOOTH AUDIO |
The Bluetooth built into the A2+ 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 A2+ 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.
Extended-range wireless. 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.
16 bit DAC |
AMPLIFIER DESIGN | The amplifiers in powered Audioengine speakers are located in the left speaker and are a conservatively-rated class A/B analog monoblock design. This is a more traditional speaker/amplifier configuration which provides excellent quality audio and greater flexibility. All circuit boards for the power and preamp sections are vertically mounted for maximum mechanical shock protection. |
DRIVER DESIGNS | 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 woofers are aramid fiber woven glass composite with rubber surrounds. Aramid fiber is obviously very strong, which means the woofer retains its shape when being driven at high levels. |
SHIELDING | 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. |
