Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
Two-Way Speaker System: Each of the Audioengine 2+ speakers has two
drivers; a 3/4" silk dome tweeter & a 2.75" Kevlar woofer. The A2+ provides a
real, natural sound; very near to the originally-recorded music. The A2+ has a
frequency response of 65Hz to 22,000Hz (+/-2dB)
- Silk Dome Tweeters: Audioengine uses
audiophile-quality, ferro-fluid cooled silk dome tweeters with neodymium
magnets. Silk tweeters hold up well under high power & the edge-driven
design gives very smooth response.
- Kevlar Woofers: The woofers are made of Kevlar woven
glass aramid composite with rubber surrounds. Kevlar is very strong, which
means that the woofer retains its shape when being driven at high levels.
Built-in Amplifier: The A2+ is powered by a 15-watt RMS x
2ch amplifier (SNR: >95dB, THD: <0.05%), built into the left speaker. The
built-in power amplifier saves space & eliminates the need to connect
Audioengine 2+ to a stereo receiver or external power amp. Simply plug the left
speaker into an AC outlet & connect the included 6.5' speaker wire from the left
speaker's binding-post terminal to right speaker's binding post terminals. All
internal components of the 2+ are tuned together, providing a more efficient
system requiring less power than passive speakers & amplifiers.
Note: With the amplifier built-in, the left speaker is
heavier than the right (4 lbs vs. 3 lbs).
Bass Reflex MDF Cabinet: One of the reasons the Audioengine
2+ has such great bass response for a compact speaker is its slot-ported
cabinet. Each cabinet features a front-firing slot-port that has been
specifically tuned for accurate bass down to 65Hz. The result is incredible low
end with minimal audible air turbulence, so you can use the Audioengine 2+
speakers with or without a separate subwoofer. The cabinets are built using 18mm
MDF with internal bracing. Internal sound-damping material reduces unwanted
reflections inside the cabinet. The cabinet edges are rounded to reduce
high-frequency diffraction effects on the front baffles. The speakers are hand
finished, then tuned and tested together to be sold in matching pairs.
Note: The speaker materials & construction are robust & extremely
durable, so speaker grilles aren't needed.
USB (type-B) port + TI/Burr Brown DAC: The Audioengine 2+ is fitted
with a USB (type-B) port and features a built-in TI/Burround Brown PCM2704C DAC.
With its USB (type-B) port and built-in digital-to-analog converter (DAC),
the Audioengine 2+ allows you to send high-quality digital audio directly from
your Windows or Mac computer's USB port. The A2+ internal DAC handles up to
48kHz/16-bit music files.
Analog Audio Inputs: The A2+ has two stereo audio inputs on the
rear-panel of left speaker. The A2+ is fitted with a 3.5mm stereo minijack input
& a stereo RCA input. There is no input selector switch, so both inputs are live
simultaneously; if different signals are presented to both inputs, they are
mixed together & both are played through the speakers.
Variable Audio Output: The Audioengine 2+ includes a
variable stereo preamp audio output so you can connect a powered subwoofer (such
as the Audioengine
S8; sold separately), other
Audioengine powered speakers, or an Audioengine wireless adapter to
daisy-chaining music to other systems around the house. This output is variable
(adjustable) so the volume level can be controlled from the A2+ or remote
Optional Wireless Adapters: Audioengine offers wireless
adapters (772W3 and
772AW2, sold separately) that can be used with the A2+ powered speakers and
its analog audio input or output. The W3 includes a Sender (transmitter) &
Receiver; the system is designed to deliver an audio signal wirelessly between
your source component & the A2+ powered speaker, or between the A2+ powered
speaker and your powered subwoofer (sold separately). The AW2 includes an iPod
Sender (transmitter) & Receiver; the system is designed to deliver an audio
signal wirelessly from your iPod/iPhone to the A2+ powered speaker for playback.
Note: The Audioengine USB Power Adapter (772USBP,
sold separately) is required in order to supply power to the 772W3 or 772AW2
Mounting Options: Both speakers have a high-density
foam isolation pad on the bottom for safe placement on your desk, stand, table,
or shelf. The optional DS1 Desktop Stands (772DS1,
sold separately), made of high-performance silicone rubber, angle the A2+
speakers upward at approximately 15° and add 1-3/4" the the height (for 8"
total). Threaded brass inserts are found on the bottom each speaker
cabinet to provide the ability to attach the speaker to free-standing floor
stands or articulating wall-mount brackets (sold separately). Audioengine recommends placing the speakers at least 3" from the back
wall for best audio performance.
Note: Both drivers (woofer & tweeter) are directly video shielded
& allow you to place the speakers within a few inches of a video monitor.
This shielding also offers protection for hard-drive digital music players.
External AC Power Supply: The Audioengine A2+ operates off of standard
household current using the included AC power adapter and detachable power cord.
The AC power adapter plugs into the left powered speaker and the included speaker wire is
used to connect the right passive speaker. An auto-standby idle mode is also
featured to conserve power when you're not playing music.
