Audioengine P4 Premium Passive Bookshelf Speakers
A high-performance bookshelf speaker pair with the same great looks and sound as our powered speakers. Experience the signature Audioengine sound and quality but without our built-in amplifiers. Beautiful, small, and affordable, P4 is the perfect choice for your living room, bedroom or office and an ideal surround speaker for use with other Audioengine speakers in your home theater or stereo system.
Why passive speakers?
The P4 passive speakers are full-sounding bookshelf speakers in a satellite-sized package. The goal with P4 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 loudspeaker.
Already have an amplifier?
"If you already have an power amp or don't want to give up that big surround receiver then the P4 is for you. The P4 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. P4 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."
Part of the Family
Audioengine 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 speakers or Audioengine wireless adapters you decide to add to your system.
The P4 passive speakers are perfect for digital hybrid amplifiers (Class-D, Class-T, etc.) as well as most stereo receivers, integrated amps, and tube amplifiers. The P4 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.
Hear the Difference
The Audioengine P4 sets a new level of quality and easy setup. Mount a pair on a wall or stand as surround speakers in a home theater system or place them on a shelf or table for a compact stereo setup. Even if you're not an audio enthusiast we guarantee you will still hear a difference!

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.
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.
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.
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.
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.
Can I use the P4 passive speakers with the Audioengine S8 sub?
To use the P4 speakers with the S8 you would need an amp, like our N22, to supply power to the P4 speakers and connect to the S8.
Why don't the P4 speakers have built in amplifiers similar to the A2 and A5 active systems?
The P4 came about from requests from customers that already have our powered speakers and/or have a music system and needed speakers but wanted the same Audioengine sound from a passive speaker.
Is the bamboo version a veneer and does the P4 bamboo version sound better than the black or white finished cabinets?
The P4 enclosure is made of solid carbonized bamboo, not a veneer. The bamboo cabinets were tuned to sound the same as the MDF speakers, but the density of bamboo will give it natural acoustic advantages over MDF material.
What amplifiers work best with the P4?
The P4 is a very efficient speaker and designed to work well with digital hybrid amplifiers (Class-D, Class-T, etc.) as well as most stereo receivers, integrated amps, tube amplifiers, and whole-house music systems such as the Sonos ZonePlayer 120. Check out our N22 amp for a great setup.
The P4 is rated at 4 ohms but my receiver has speaker outputs listed as 8 ohms. Will the P4's work with my receiver?
The lower the speaker impedance, the more current (amperage) your amp or receiver will need to provide, but most separate power amps have more than a sufficient power supply and power amp sections for driving 4 ohm loads with ease. In fact many amps will perform better with a 4 ohm load as opposed to 8 ohms if their design is robust enough to supply the extra current. A quick web search will bring up more information on this subject.
P4 Troubleshooting Tips
- Make sure all of your connections are complete and all of your cables are in working order, test two or three different audio cables.
- Check your speaker wire to make sure it is connected well, and is the proper polarity (Red to Gold, Black to Silver) on both ends.
- Use as many different input sources with your amp as possible to see what happens.
- Swap your left and right speaker to see if the issue remains in the same channel or follows the speaker.
- Remove any preamps, conditioners or wireless devices one at a time.
- Test your speakers in a different location or with a different amplifier to see if something is causing interference in the current location or setup. Something as simple as a router, cordless / mobile phone, halogen lamps, etc. near the speakers may be causing the issue.
If the problem persists please provide us with the results of your troubleshooting. Please also include the date, purchase location, and serial number for warranty purposes. If you live outside of the continental US you will need to contact your dealer or our distributor in your country for further assistance. Visit Distributors Website
