Custom built

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.

Drivers

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 that the woofer retains its shape when being driven   at   high levels. The speaker materials and construction are robust enough to     stand up to some serious thrashing, so speaker grills are not needed   and they   will sound and look great after many years of use.

Power amplifiers

The amplifiers in Audioengine speakers are   located in the left speaker   and are a conservatively rated analog   design. All components are tuned   together for each model, 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 mounted for maximum mechanical   shock   protection.

Power transformers

Power transformers are a large contributor to   the overall audio   performance, especially in the low end. Again, no   off-the-shelf parts.   Audioengine uses gapless core toroidal   transformers which have a tighter   radiated magnetic field, directly   translating to lower noise. They are   lighter than standard, lower-cost   transformers and also generate less heat.

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.

Usb power

The Audioengine 5+ includes a 5V, 500mA USB   power supply for charging   portable devices, while listening to your music. The USB connector allows you   to charge and power your   Smartphone, Tablet, Audioengine wireless adapters or any other USB   powered product. USB is for power only, not USB audio or data transfer.
