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. The A5+ cabinet contains tuned, rear-port slots.
Furniture Grade Finishes
The A5+ cabinets are available in several handsome finishes, including bamboo veneers as well as satin black and high-gloss white paint, offering a wide choice for complementing room furnishings.
Custom Components
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.
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 all Audioengine speaker systems.
Efficient Integrated Design
The speaker cabinets, drivers, innovative bass port designs, amplifiers, and passive crossovers are all critically tuned together for each Audioengine model. This, in turn, makes for a much more efficient system that requires less power than passive speakers and a separate integrated amplifier or similar A/V components. We build all this goodness into the left speaker cabinet to make it super-easy to connect your smartphone, tablet, computer, TV, network player or any other audio product.
High-quality Bluetooth Audio
The Bluetooth built into the A5+ powered speakers features aptX HD coding which is an advanced Bluetooth audio codec with very impressive sound. And even if your phone or tablet does not have aptX HD, the A5+ Bluetooth solution is backwards-compatible with SBC and AAC codecs, as well as standard aptX, so you can wirelessly stream music from any Bluetooth-enabled device and still enjoy all your music. High-fidelity Bluetooth aptX HD that really works and sounds great. Here is why:
Extended-range wireless.
Most Bluetooth implementations have very limited range, typically within just one room. But with careful signal management circuitry and antenna tuning, we offer a superior solution that has up to 3 times the range of standard Bluetooth for multi-room use, with no degradation in audio quality.
24 bit DAC
The A5+ include an PCM5102 DAC, widely known for its low-noise and high-fidelity. But for Bluetooth the PCM5102 is used as an upsampling DAC and will pad all bit depths to 24 bit, achieving a higher signal-to-noise ratio and lower noise floor. Due to the high signal-to-noise specs of the PCM5102, the fact that digital signal is upsampled to 24 bit as well as the added benefit of onboard triple redundancy power source conversion and filtering, the A5+ Bluetooth implementation presents impressive low noise and low distortion characteristics with a noticeable improvement over other Bluetooth devices.
Amplifier Design
The amplifiers in powered Audioengine speakers are located in the left speaker and are a conservatively-rated class A/B analog monoblock design. This is a more traditional speaker/amplifier marriage which provides excellent quality audio and greater flexibility. All circuit boards for the power and preamp sections are vertically mounted for maximum mechanical shock protection.
Driver Designs
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 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.

Troubleshooting
A5+ Wireless Troubleshooting Tips
The following troubleshooting tips can help diagnose and correct most concerns with the A5+ Wireless. We have attempted to make this list as comprehensive as possible, so some of these may not apply to your issue, but please go through each tip.
If the power indicator on the front panel is not illuminated, then try these tips:
● Verify that the AC power cord is connected to the speaker rear panel and to a working
AC power outlet.
● Check that the speaker’s power switch is in the ON position.
● Check that the rear panel voltage selector matches the operating voltage in your country
or region.
If there is still no power, check the fuse in the rear panel. If the fuse is blown and needs
to be replaced it is important to replace with the same fuse type and value.
If the front panel indicator light is on but you are experiencing an audio-related or other issue with a wired connection, try these tips:
● Power-cycle the speakers by switching them off and back on using the power switch on
the rear panel.
● Be sure the speakers are not in MUTE or SLEEP mode (if so, the front panel indicator
light will be flashing).
● Check that the cables from your audio sources to the speaker are properly connected.
Confirm by unplugging the audio cables and then reconnecting. Try using as many
different inputs and input sources as possible to see if the problem follows.
● Check speaker wire connections from the left (powered) speaker to the right (passive)
speaker. Confirm by removing the speaker wire from on each speaker and
reconnecting. Also check speaker wire polarity by verifying that the wires are going to
same terminals on both speakers.
● Verify that your audio input source components or devices are all powered on and the
volume levels are turned up.
● If using a computer, verify that the audio output balance setting is centered for the OS
and all apps.
● Make sure the speakers are not too close to a wall or other obstruction, which could limit
bass output.
● Decrease the volume level of the audio input source and increase the volume of the
speakers.
● If you are using a wireless adapter, preamp, or external DAC with these speakers,
remove these (temporarily) and connect the audio source directly to the speakers.
● If your input source has its own EQ or other sound settings, make sure they are all
temporarily turned off.
● Also try moving the speakers to a different location to see if something is causing
interference in the current location. Something as simple as a wireless internet router,
cordless or mobile phone, or halogen lamp near the speakers can all cause interference.
If you’re having Bluetooth-related issues, try these tips:
If your A5+ Wireless is already connected to a device, the Pair LED on the rear of the left
speaker will be on and solid; if your A5+ Wireless has been idle (and not connected to a device)
for more than 2 minutes, the LED will be off. Tap the LED and it should begin blinking (or pair to
your A5+ Wireless using your source device, and the LED will go from off, to on and solid). If
your A5+ Wireless’ LED indicator doesn’t light up, try using a different AC outlet, and check to
see that any wall outlets or surge protectors are switched to the “On” position and are in working
order.
● Try playing audio from more than one application on your phone/tablet, or computer.
● Check to make sure your source device is running the most up to date version of
software available.
● Try disconnecting from and forgetting the A5+ Wireless through your source’s Bluetooth
settings, and re-pairing to the A5+ Wireless.
● Try using a different source device with your A5+ Wireless to see if the issue follows.
Also be sure to test your A5+ Wireless using the analog input as well.
● If at all possible, try your A5+ Wireless in a different location and / or setup to see if
something is causing interference in the current location.
A5+ Wireless troubleshooting tips – remote control
Remote control is not working or remote range is reduced.
● Make sure nothing is blocking the remote control receiver, which is in the left powered
speaker.
● Check the remote battery to be sure it is installed correctly.
● Replace the battery with another CR2025 battery
