Custom Built

Audioengine designs and manufactures our own tweeters, woofers, and many other critical components. In other words, these are not "box built" speakers with off-the-shelf parts but entirely custom-designed to our specifications. What we do not fabricate directly in our speaker factory we have custom-made to our designs (parts such as toroidal 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 traditional AV stereo receivers and passive speakers.

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 Audioengine speakers.

Drivers

Audioengine uses audiophile quality, ferro fluid 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 Kevlar woven glass aramid composite with rubber surrounds. Kevlar 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.

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. Each cabinet contains tuned, front-port slots. Both speakers are tuned and tested together and sold in pairs.

Power Amplifier

The amplifiers in Audioengine speakers are located in the left speaker and are a very conservatively rated analog design. Each subsystem is tuned together for all models, which provides a much more efficient system requiring less power than passive speakers and separate amplifiers. Circuit boards for the power and preamp sections are vertically mounted for maximum mechanical shock protection (a good thing).

Shielding

Both drivers are magnetically 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.
