Audioengine A2+ Wireless

Features

Two-Way Speaker System: Each of the Audioengine A2+ Wireless speakers has two drivers; a 3/4" silk dome tweeter & a 2.75" Kevlar woofer. The A2+ Wireless provides a real, natural sound; very near to the originally-recorded music. The A2+ Wireless 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+ Wireless 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 A2+ Wireless 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 A2+ Wireless 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 A2+ Wireless 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: No grilles are included.

16-Bit/48kHz DAC: The Audioengine A2+ Wireless speakers utilize a 16-Bit/48kHz Burr Brown DAC (digital-to-analog converter) from Texas Instruments (TI) for exceptional sound quality when listening to Bluetooth wireless audio or your computer's USB audio.

Note: Bluetooth and microUSB share the internal DAC, so you can only listen to one at a time, and Bluetooth takes priority. If you're using microUSB for example, and start using Bluetooth, microUSB will mute and Bluetooth will take over. Depending on your source, if you pause or disconnect from Bluetooth the speakers may automatically switch back to microUSB after a few seconds.

Bluetooth Audio Streaming: The Audioengine A2+ Wireless speakers are equipped with built-in Bluetooth 5.0 for wireless audio streaming (A2DP) from your Bluetooth-enabled smartphone, tablet, desktop computer, or laptop. You'll be able to wirelessly stream stored music, music apps, and other audio content from your Bluetooth source device to the A2+ Wireless speakers. In addition to Bluetooth's standard SBC codec, the A2+ Wireless supports AAC for higher quality sound from Apple iOS devices and aptX for "CD-like" (16-bit/48kHz) sound from many Android and Mac devices. The Audioengine A2+ Wireless speaker system has a wireless Bluetooth range up to 100' and a delay of approximately 30ms (milliseconds).

microUSB Port: The Audioengine A2+ Wireless is outfitted with a microUSB port for connection to your Windows PC or Mac computer. You'll be able to playback your laptop or desktop computer's music library through the A2+ Wireless speakers. The microUSB port bypasses the the DAC in your computer and utilizes the A2+ Wireless speaker's 16-bit/48kHz DAC to producce high-quality sound. No separate USB drivers are need for Windows or Mac.

Note: The microUSB port does not support playback from Apple iPod/iPhone/iPad, Android smartphones/tablets, or USB MSC (mass storage class) devices.

Analog Audio Inputs: The A2+ Wireless has two stereo audio inputs on the rear-panel of left speaker. The A2+ Wireless 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.

Note: The analog inputs on the A2+ Wireless are always active. They will play at the same time as the Bluetooth or USB input.

Variable Audio Output: The Audioengine A2+ Wireless 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 (772W3; sold separately) 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+ Wireless or remote control.

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+ Wireless speakers upward at approximately 15° and add 1-3/4" the the height (for 8" total). 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+ Wireless 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.
