Enjoy your audio from nearly any source with this pair of Audioengine HD3 2-Way Wireless Bookshelf Speakers. They feature Bluetooth with aptX for wireless connectivity, stereo RCA and 1/8" inputs for traditional wired devices, and a micro-USB input for a dedicated input from your computer. The HD3 has a 2-way design with a built-in 15W per channel amplifier. Each speaker sports a 2.75" Kevlar woofer and a 0.75" silk dome tweeter.
No Missed Connections
Connect to the HD3 any way you like: wirelessly or wired, digital or analog. Stream your music library, TIDAL, Spotify, Pandora, YouTube, etc. to the HD3 from just about anywhere in your house (within 100') without dropouts. Wireless setup is designed for simplicity and only takes about a minute. And if you're using the HD3 on your desktop, connect it with a USB cable. The USB input bypasses your computer's built-in headphone jack for an enhanced listening experience. If you're not keen on USB or wireless, you can still use any stereo RCA or 1/8" audio cable to connect.
Bluetooth and aptX
The HD3 is designed to easily connect to any of your devices that have Bluetooth, but for enhanced sound quality, use a device that supports Bluetooth aptX. For Apple devices that don't have aptX, such as the iPad or iPhone, Apple generally uses the AAC codec. It sounds good as well, and you'll get the extra benefit of the upsampling 24-bit DAC.
The HD3 Bluetooth receiver and USB input both utilize the AKM AK4396A DAC, which is designed for low-noise and high-fidelity. The AK4396A 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 AK4396A, the fact that digital signal is upsampled to 24-bits – as well as the added benefit of onboard triple-redundancy power source conversion and filtering – the HD3 Bluetooth implementation presents low noise and low distortion characteristics with a noticeable improvement over other Bluetooth devices.
The speaker cabinets, drivers, bass port designs, amplifiers, and passive crossovers are all tuned together specifically for the HD3. This is designed to provide for a more efficient system that requires less power than passive speakers and a separate integrated amplifier or similar A/V components.
HD3 Headphone Amplifier
The HD3 contains a headphone amplifier based on the OPA2134 low-noise opamp. This amp is designed to provide low-impedance, high-fidelity audio and a 2V output, which can drive a wide range of headphones.
The amplifiers in the HD3 are located in the left speaker and are a class A/B analog monoblock design. This is a more traditional speaker/amplifier configuration, which is designed to provide quality audio and greater flexibility. All circuit boards for the power and preamp sections are vertically mounted for enhanced mechanical shock protection.
The HD3 uses ferrofluid-cooled silk dome tweeters with neodymium magnets. Silk tweeters are fashioned to hold up well under high power, and the edge-driven design gives a smooth response. The woofers are Kevlar-woven glass-aramid composite with rubber surrounds. Kevlar is designed for strength, so the woofer can retain its shape when being driven at high levels.
