Materials And Construction

0.7" (18 mm) thick MDF cabinets with real wood veneer
1" (26 mm) silk dome tweeters with neodymium magnets
5.5" (140 mm) aramid fiber woofers with advanced voice coils

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 HDP6 cabinet contains tuned, rear-port slots.

Furniture Grade Finishes

The HDP6 cabinets are available in several handsome finishes, including walnut and cherry veneers as well as satin black paint, offering a myriad options for complementing room furnishings. Also included are detachable grills that add further aesthetic advantages as they are firmly held in place with hidden neodymium magnets for a clean look.

Custom Components

Audioengine designs and manufactures our own speaker drivers and other critical components. In other words, the HDP6 is not a box-built system with off-the-shelf parts, but includes custom-designed components constructed to our specifications. What we do not fabricate directly inside our factories we have made to our specific designs and parts such as circuit boards, transformers, magnets, and wiring harnesses, for example.

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.

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 the woofer retains its shape when being driven at high levels. The HDP6 woofers are housed in cast aluminum frames which provide high rigidity and increased heat dispersion.

Troubleshooting

HDP6 and P4 Troubleshooting Tips

The following troubleshooting tips can help diagnose and correct most concerns with the HDP6 or P4. 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.

  1. Verify that the power controls for your amp, preamp, and/or AV receiver are powered on and working.
  2. Check that the volume level of your audio source components or devices are turned up.
  3. Check the speaker wire connections from your amp to the speakers by removing the speaker wire from each speaker and then reconnecting.  Also check the speaker wire polarity by verifying that the wires are going to the same terminals on both speakers.
  4. Check that the cables from your audio source(s) to the amplifier are properly connected. Confirm this by unplugging the audio cables and then reconnecting.
  5. Try using different audio input sources and/or devices to see if the problem follows.
  6. Try swapping inputs to the left and right speaker to see if the issue remains in the same channel or follows the speaker.
  7. If you are using a computer with your setup, make sure the volume is up on your media players, internet radio, master control, device volume, etc. and that the balance control is centered.
  8. If you are using a wireless adapter, preamp, or external DAC, remove these (temporarily) and connect the audio source directly to the amp/speakers.
  9. If your input source has its own EQ (equalizer), please make sure the low end is at a moderate level as having too much bass can cause distortion.
  10. Move your amp and HDP6/P4 speakers to a different location to see if something is causing interference in the current setup.  Something as simple as a wireless internet router, cordless or mobile phone, or halogen lamp nearby can cause interference.

FAQ's

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.

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.

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.

The N22 can work with the HDP6s, but we would recommend using the speakers with an amplifier that can provide more power to the speakers than the N22 can provide.

The HDP6 came about from requests from customers that already have our powered speakers and/or have a music system and needed speakers but wanted the same Audioengine sound from a passive speaker.

Yes!  You would just need an amp to supply power to the HDP6 speakers and connect to the S8.

The lower the speaker impedance, the more current (amperage) your amp or receiver will need to provide, but most separate power amps have more than a sufficient power supply and power amp sections for driving 4 ohm loads with ease. In fact many amps will perform better with a 4 ohm load as opposed to 8 ohms if their design is robust enough to supply the extra current. A quick web search will bring up more information on this subject.

The HDP6 is a very efficient speaker and designed to work well with digital hybrid amplifiers (Class-D, Class-T, etc.) as well as most stereo receivers, integrated amps, tube amplifiers, and whole-house music systems such as the Sonos ZonePlayer 120. The HDP6s have an amplifier power rating of 10-150W per channel, so any amplifier that outputs that power should work great!
