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 A1-MR cabinet   contains tuned, front-port slots.

Furniture grade finishes

The A1-MR cabinets are in versatile, grey finish 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.               

Amplifier design

The amplifiers in powered Audioengine speakers are located in the left speaker and are a conservatively-rated class D analog monoblock design. This is a more traditional speaker/amplifier marriage 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 fibre woven glass composite with rubber surrounds. Aramid fibre 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.
