Wall or Ceiling Mount
The 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.

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 AP4 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.
