HDP6 speakers include standard 1/4″ threaded inserts on the bottom of each HDP6 cabinet for attaching to a speaker mount or bracket. We recommend using products by companies such as OmniMount or Sanus. Before installing mounts or brackets make sure you consult all documentation and carefully follow the installation instructions.

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.

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.

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.

The HDP6 cabinets are available in several handsome finishes, including walnut and cherry veneers as well as satin black paint, offering a myriad of 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.

Both drivers are directly magnetically shielded which allow you to place the speakers within a few inches of a video monitor. This shielding also offers protection for hard drive-based digital music players.
