Wall or Ceiling Mount
The P4 speakers include two standard 1/4" threaded
inserts on the rear panel and another insert on the bottom of each P4 cabinet
for attaching 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.
Custom Built
Audioengine designs and manufactures our own tweeters,
woofers, and many other critical components. In other words, these are not
"box built" speakers with off-the-shelf parts but entirely
custom-designed to our specifications. What we do not fabricate directly in our
factory we have custom-made to our designs. The cabinets, drivers, bass port
designs, and crossovers are all painstakingly tuned together for each model.
Drivers
Audioengine uses audiophile quality, ferro fluid 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
Kevlar woven glass aramid composite with rubber surrounds. Kevlar 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.
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 P4 cabinet
contains tuned, front-port slots.
Shielding
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.
