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.

The HD3 is expandable, so if you want deeper bass, just connect your subwoofer.

The HD3 includes a dedicated headphone output on the front panel, so you can listen without waking the neighbors. Its headphone amplifier is designed to deliver quality sound that drives even the most demanding headphones.

The HD3 features aluminum trim accents and detachable magnetic grilles designed to blend with any décor.

Built-in power amplifiers save space and eliminate the need to connect the HD3 to a stereo receiver or external power amp. Simply plug the left speaker into a power outlet and connect the included speaker wire from the left to the right speaker. All internal components of the HD3 are designed and tuned together for a more uniform sound than traditional separate speakers and amplifier.

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.

Features from the Audioengine B1 aptX HD Bluetooth receiver and D1 24-bit DAC are combined in the HD3 to help make it a complete digital audio system.

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 HD. For Apple devices that don't have aptX HD, 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.

Through signal management circuitry and antenna tuning, the HD3 offers a solution that has up to three times the range of standard Bluetooth for multi-room use with no degradation in audio quality.

The HD3 Bluetooth receiver and USB input both utilize the PCM 5102 DAC, which is designed for low-noise and high-fidelity. The PCM 5102 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 PCM 5102, 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 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.

The speaker drivers in the HD3s are directly magnetically shielded.

Q: 7. What is the difference between the A2+ model vs the A1 model?

A: The Audioengine A2+ Wireless Bluetooth Speaker System with S6 6" 210W Subwoofer Kit (Satin Black), BH # AUA2PBTBLKS6 (B&H Kit), offers the following differences over the A1speakers according to Audioengine: The A1 and A2+ are both premium powered stereo speakers, with high-quality aptX Bluetooth for quick and easy connection to any app or device. Modeled after the A2+, the A1 also boasts precision tuned, hand-crafted cabinets, uses the same silk dome tweeters and aramid fiber woofers, and features an aux audio input and subwoofer connection. Where the A1s differ, however, are in the types and styles of connections and the finish style of the cabinets. The A1 speakers use spring clips for the speaker wire connections rather than 5-way binding posts and, unlike the A2+, do not offer RCA or USB connection options. The A1 hand-finished cabinets feature vinyl exterior finish rather than the painted finish offered on the A2+.

Q: 8. Can these be used as computer speakers? I like a lot of bass, and currently using klipsch pro media 2.1 speakers.

A: I believe A5+ can be computer speakers because they are active speakers comes with amplifier embedded. However, they are too big if you put them next to my 27 monitor. Imagine it will looked so out of proportion with smaller monitor. I suggest you use A2+ and add a subwoofer to give better bass than A5+ can provide. A2+ will be less costly. Money saved can pay a portion of a sub. I currently use A5+ on speaker stands with a 4K TV, which put out terrible sound quality. I am an audiophile and I cannot recommend A5+ or A2+ as hifi speakers for music listening. They are just OK speakers and cost effective.

A: It is not recommended but sure you can do that and they will still work good. The A5+ does not come with any attachments for a stand, they are made to sit on any flat surface.

Q: 10. Can the be played with 240V power supply?

A: Yes, these speakers are dual voltage. 115/240VAC, 50/60Hz selectable.
