Just like the Good Old Days

Nothing beats the warm, pure tone of an analog amplifier. Which is why you'll find them in Audioengine's HD3 music system. Our built-in analog power amplifiers sound remarkable compared to lower-cost digital amps found in other mass-produced brands. At Audioengine, we're always looking forward. Unless we're talking about amplifiers. And then we're always looking back.

Questions & answers about the HD3 Wireless Speaker System (Open Box)

Sure, for HD3 you will need an inverter that can supply about 50-60 watts.

Absolutely!  You can connect any Audioengine speaker with an analog output to any Sonos product that has the Line-In feature.  You can also connect any Audioengine passive speakers into an existing Sonos system using the Sonos Amp.

Absolutely! To do so:

  • Open the Alexa App on your smartphone or tablet (Apple link  |  Google Play Link)
  • Tap the “Devices” icon and select the Echo/Alexa device you want to connect to speakers
  • Select “Bluetooth Devices”
  • Select “Pair New Device”
  • Find your Audioengine wireless speaker on the list of available Bluetooth devices, and select it

Yes, you can. The HD3 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.

Yes! We incorporate all the relevant functions and features from Bluetooth 5.0 that apply to our products! These features include; extended range, low latency (so that video and audio sync properly), as well as higher level aptX-HD, aptX, and AAC codecs (with the exception of our 512 portable speaker which supports SBC only). Keep in mind that the capability of the source is what controls the Bluetooth experience.

All turntables require a phono preamp stage before connecting to Audioengine speakers. Many turntables have this built-in , while others do not and would require an external phono preamp. Check the turntable manufacturer’s website or user manual. Some turntables may even include Bluetooth, in which case you can pair and connect them to the speakers wirelessly!

Yes they do! They are equipped with a power-saving circuit that turns off the speaker's final stage amp. This idle mode activates right after you stop playing music. Due to this power-saving function, it's perfectly fine for the speakers to stay on all the time!

Yes, there are multiple audio inputs on Audioengine powered speakers and both inputs are "open" or active so you can leave your audio sources connected at the same time.

Some turntables will need a preamp before being connected and others may have one built-in. Check the turntable manufacturer’s website or user manual.

While the HD3 has a fantastic 24-bit DAC, you can always run your own external DAC to the speakers by connecting to the analog inputs.

Our HD3'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. Next, connect the powered speaker to the right passive speaker using the included upgraded speaker wire with banana plug tips. Finally, plug in your music (cell phone, turntable, computer, laptop, etc.) with the supplied cables or via Bluetooth and you're ready to go!

Here is a quick video that can be used as a reference:

(Please note - there is no audio associated with the video.)

Absolutely! This is especially useful for connecting wired with newer Smartphones that do not have a headphone jack output. You'll need the correct USB-A adapter cable to connect from your tablet to the USB input on the HD3. These are generally available from the manufacturer of your tablet/smartphone, local electronic stores, or even online retailers.

The HD3 speakers do include detachable magnetic grills. The grills have thin rubber pads to prevent marks or damage to the finish or the cabinet, so your HD3s will keep looking great even if you like to remove / replace them frequently!
