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.

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!
