Why passive speakers?
The AP4 passive
speakers are full-sounding bookshelf speakers in a satellite-sized
package. The goal with AP4 was to design a small but powerful bookshelf
speaker for people that already have surround receivers or amplifiers
and are looking for the same Audioengine sound and quality in a passive

surround receiver then the AP4 is for you. The AP4 has excellent bass
response for its size, which is evident when used either as stereo
speakers or as satellite surround speakers in your home theater setup.
AP4 sounds great sitting on stands, on a bookshelf, or mounted on a
wall using the integrated threaded inserts which are compatible with
most wall or ceiling mount bracket systems.

active and passive speaker models share a similar "voicing" and overall
tuning so that you are assured a matched system no matter which of our

are perfect for digital hybrid amplifiers (Class-D, Class-T, etc.) as
well as most stereo receivers, integrated amps, and tube amplifiers.
The AP4 has a 4 ohm impedance rating but will sound great when
connected to almost any receiver or power amp with 4, 6 or 8 ohm
speaker output impedance.

Wall or Ceiling Mount
AP4 speakers include two standard 3/8" threaded inserts on the rear
panel and another insert on the bottom of each AP4 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.
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

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.
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 AP4 cabinet contains tuned, front-port slots.
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.
