MATERIALS AND CONSTRUCTION
0.5″ (13 mm) thick MDF cabinets
4″ (102 mm) aramid fiber woofers with advanced voice coils
0.75″ (20 mm) silk dome tweeters with neodymium magnets
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 P4 cabinet contains tuned, front-port slots.
FURNITURE GRADE FINISHES
The P4 cabinets are available in several handsome finishes, including bamboo veneers as well as satin black and high-gloss white paint, offering a wide choice for complementing room furnishings.
Audioengine designs and manufactures our own speaker drivers and other critical components. In other words, the P4 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.
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 that the woofer retains its shape when being driven at high levels. The speaker materials and construction are robust enough to stand up to some serious thrashing, so speaker grills aren’t needed. In other words, we did our homework on the speaker drivers and they will sound and look great after many years of use.
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.
