The Kanto YU2, while a competent competitor in the budget speaker market, is designed with basic functionality in mind. It offers a basic digital audio connection via USB and a minimal physical footprint, making it suitable for desktop environments where space is at a premium. However, it lacks the robust feature set and acoustic fidelity that define the A2+, positioning it as a more entry-level option.

Audioengine A2+ Exclusive Advantages

Beyond delivering exceptional sound quality, the A2+ excels with user-friendly features such as extended-range wireless Bluetooth aptX and multiple input options, ensuring seamless connectivity across devices. This simplicity extends to the speaker's operation, where inputs are always ready to accept signals without the need to toggle between sources manually, making the A2+ both powerful and incredibly convenient for daily use.

Customer Service and Warranty

Audioengine is dedicated to exceptional customer service and reliability, offering a comprehensive 3-year warranty on all products, which far surpasses the industry standard. This commitment is highlighted by the unique 30-day audition period, allowing customers to experience the quality of the A2+ in their own space. Moreover, Audioengine prides itself on US-based customer phone support where clients can speak directly to knowledgeable staff who work collaboratively to resolve any issues. This contrasts with Kanto's offering, which includes only a 2-year warranty, reflecting a lesser commitment to customer assurance and product longevity.

Pros and Cons

We take great pride in our products, and go through great lengths to ensure consistency and quality. For that reason, this item was randomly selected for an additional step of Quality Assurance.

Yes!  As long as your speakers have an analog output (either RCA outputs or a 3.5mm stereo mini output), you can absolutely connect the S6 to your powered speakers.  With the exception of the B2, all of our powered speakers will have the outputs needed to connect the S6, this includes the original A2 and A5 models. You can simply use RCA cables to connect the S6 to the A2+, HD3, HD4, A5+, A5+Wireless, and HD6 speaker models. For the A1 and A1-MR speakers, you can use one side of your stereo RCA cables. Just use the left/white RCA cable, and leave the red RCA disconnected to prevent an accidental ground loop. ** Please note:  a 3.5mm/stereo mini cable will not work with the ‘Subwoofer’ output on the back of your A1/A1-MR speakers. **

No, there are no firmware updates or special drivers needed unless you own our A1-MR multi-room speakers or our B-Fi multi-room wireless streaming device. If a firmware update is released for the A1-MR or the B-Fi, you will be notified of the update the next time you open the Audioengine Control App.  If an update is needed, simply click "update" on the DEVICES page next to the product that needs to have the firmware update applied.  The app will handle the rest of the process from there! Standard plug-n-play drivers that are provided by your computer's OS are utilized when using the USB input on our A2+, HD3, and HD4 speaker models. And all of our Bluetooth speakers/products are compatible with any device that supports Bluetooth, and the A2DP profile for streaming stereo audio. This includes most smartphones, tablets, and computers. For computers that don't include Bluetooth support out of the box, you can simply add a USB Bluetooth adapter.

                                          Applicable to our A2+, HD3, HD4, A5+, A5+Wireless, and HD6 speakers.

Start with power cycling your speakers by turning them off and then back on.  From there:

1. Determine if the distortion is due to your source by disconnecting all source devices from the speakers.
2. Please make sure all of your connector cables are in working order. Try different cables as well as a different source device.
3. Please try using each input available (mini-jack, RCA, USB, as well as Bluetooth), one at a time, to see how the speakers react. If the distortion is unique to one speaker, when testing via RCA switch the RCA jacks (red to white and white to red) to see if the issue remains in the same channel.
4. Make sure it is not a power issue by trying a power outlet that is on a different circuit.

Applicable to our A1, A1-MR, A2+, HD3, HD4, A5+, and HD6 speaker models

If one of your speakers is not working (whether it be the left or right speaker), we would recommend the following troubleshooting steps: Start by power cycling your speakers by turning them off and then back on.  From there:

1. Check to make sure the speaker wire connecting the left and right speakers is connected according to proper polarity (Red to Gold, Black to Silver) on both ends.
2. Please make sure all of your connector cables are in working order. Try different cables as well as a different source device.
3. If you are using any other devices in line with these speakers, please temporarily remove them from your setup and connect the source directly to the speakers
4. Please try using each available input, one at a time, to see how the speakers react. When testing via RCA swap the RCA jacks (red to white and white to red) to see if the issue remains in the same channel.

On the A2+ Wireless/HD3 models with an external power supply brick, first test it by plugging into wall power and observing the LED light on the brick to see if its solid, blinking, out. If it's blinking or out, the power supply is likely faulty. If the light is solid, proceed to plugging into the speaker and observe the power supply brick LED once more. If it's blinking or out, there is likely an issue with the internal amp. Contact support if either has an issue.

This sometimes happens when the speakers and turntable share the same surface. The vibrations from the speakers playing feedback into the turntables stylus, causing unwanted noise. The best way to mitigate this would be to place the speakers on a different surface. If that's not an option, we'd recommend trying out some isolation stands. For larger speakers like A5+ and HD6, the ones made by Isoacoustics work well.

If the left speaker is in an easy to reach location, you can certainly use the physical knob to set volume. If not though, it's perfectly fine to set the speakers to a good volume and then adjust from your source moving forward. Every setup is different, so some experimentation will be necessary to find your preferred settings.

Our A2+'s are an all-in-one system with no extra components needed except your phone or computer. Simply place the speakers where you want them and connect the power supply. Hook up the included speaker wire from the powered left speaker to the right passive speaker. Then connect your music source with the supplied cables - or go wireless with any Bluetooth enabled source device, like a computer, smartphone, or tablet. Here is a quick video that can be used as a reference: A2+ Setup Video (Please note - there is no audio associated with the video.)

The A2+s do not include detachable magnetic grills.

All you would need to do is connect the variable output of the A2+ into the input of your sub using RCA cables.

You wouldn't be able to use a pair of headphones directly with the A2+s; in order to use headphones with the A2+s, you would need to include something with a dedicated headphone amp, such as our D1. All you would need to do is plug the D1 into your computer (either with an optical or USB cable) and connect the D1 from its RCA outputs into either of the inputs of your speakers.

In the new A2+, we've included a linear limiter which will manage the bass at the point where bass distortion starts to occur. Being a linear limiter, it will not chop the signal but instead retains the shape of the waveform, not allowing it to go into distortion. This means if you listen to the A2+ at higher levels you'll notice the bass response is tamed and not as boomy. It’s important to note that the limiter will have no effect at normal listening levels.

Yep, an AC wall outlet near the A2+ is all you need to power the AW3 wireless Receiver.

Some turntables will need a preamp before being connected and others may have one built-in. With that in mind, it is best to check the turntable manufacturer’s website, the turntable’s user manual, or you can even try your turntable without the preamp first to see how it operates.

If you’ve connected your turntable to your speakers and the volume is low, one of two situations may be happening: If you have a turntable with a built-in phono preamp, such as the Audio-Technica ATLP120 or the Music Hall USB-1, the output may be in the wrong setting. Double check and make sure the switch is set to “line” instead of “phono.” Be careful to keep the volume of your speakers low as it can be quite loud if you had to switch it to "line". Your turntable could also not include a built-in phono preamp, such as older turntables. If your turntable does not include a built-in preamp, you will need to add an external preamp to bring the signal up to a line level signal. We don’t have any recommendations on a particular brand or model preamp to use with this setup.

Sure, for A2+ you will need an inverter that can supply about 50-60 watts.

Yes, you can.   The A2+ speakers use a switching power supply so it will automatically convert to the different voltage. The power cable is  also detachable which makes it convenient to replace the AC plug with a different type if you don't want to use an adapter plug.

Plug the W3 AC Power Supply (one adapter is included with the W3) into an AC outlet, connect the W3 Receiver into the adapter, and run the mini-jack cable from the Receiver to the A2+'s. If you're not using your W3 transmitter with a computer, and need a second power supply for your setup, you can find extra power supplies here. You can also use spare USB phone or tablet chargers to power the W3, just make sure they can supply at least 500mA.

The A2+ is equipped with a power-saving circuit that turns off the final stage of the speaker's amplifier when no input signal is detected, so you can absolutely leave them on when not in use. This activates right after you stop playing music, and is instantaneous (as soon as the input signal stops and it disengages automatically once an input in reintroduced), so there shouldn't be a noticeable delay when resuming audio. It's also fine to power off your speakers when not in use if you prefer.

While the DAC in the A2+ is better than what might be built in to most computers, adding a 24 bit DAC, like our D1 or D3, would still be a benefit to audio quality.

Yes. You will need to pick up the USB Camera Adapter from Apple, which allows a USB connection to the iPad (and, as of iOS7, the iPhone). Then just hook up as you would from a computer.

We researched adding a bamboo version to the A2+ line, but found that the speaker size is actually too small and costly to produce them in bamboo using the same process as with our A5+ and P4 speakers.

Here are the upgrades made to the A2+:

• USB digital-to-analog converter (DAC)
• Variable audio output (connect a subwoofer or wirelessly send audio to other speakers with our optional W3 wireless adapter)
• Upgraded speaker connectors
• Upgraded power supply
• Upgraded accessory cables
