Phew ! Those are a lot of specifications!

Some of you may be intimidated by looking at that long list of specifications, but a lot of it isn’t terribly important to understand anyway since audio that measures better in specs may not actually sound better. However, some of the specifications do reveal a few aspects of the system and helps a customer make a decision.

First off the product is a 2.0 speaker system. That means no subwoofer for enhanced bass and conversely a much smaller footprint which makes it easier to install in a location. Secondly the lack of a subwoofer is shown in the frequency response. Now most manufacturers exaggerate the frequency specs of their speakers but Audioengine must be given credit of being more accurate in their frequency specs. First off the bass goes down to just 65 Hz which means sub bass may not be prominent.

Thirdly the DAC that Audioengine chose for their A2+ is a Texas Instruments/Burr Brown PCM2704C chip which is well respected DAC chip. Lastly, the built-in DAC is 16 bit and doesn’t support 24-bit music. However on this speaker system the benefits of 24 bit music will be hardly realized so its not a big issue here. Accessories wise the package comes with everything you will need to use the speaker setup and the included cables are of a high quality which is much appreciated.
