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.
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.
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.
