Key Differences
- Impedance: Audioengine P4 at 4Ω vs MartinLogan 839IC6HT at 8Ω. Lower impedance draws more current from your receiver. A 4-ohm speaker needs a receiver rated for that load, or you risk thermal shutdown during loud passages.
- Freq Response High: Audioengine P4 at 22000Hz vs MartinLogan 839IC6HT at 20000Hz
- Freq Response Low: Audioengine P4 at 60Hz vs MartinLogan 839IC6HT at 55Hz. Determines how much bass a speaker handles on its own versus relying on a subwoofer for low-end support.
- Driver Config: Audioengine P4 at 2-way bass reflex vs MartinLogan 839IC6HT at 2-way angled. 3-way speakers use dedicated drivers for bass, midrange, and treble, reducing crossover interference. Coaxial designs (KEF Uni-Q) mount the tweeter inside the woofer for better time-alignment.
- Sensitivity: Audioengine P4 at — vs MartinLogan 839IC6HT at 89dB. Higher sensitivity means your receiver works less hard, leaving more headroom for dynamic peaks in movie soundtracks. A speaker rated 3 dB higher in sensitivity needs half the amplifier power to reach the same volume.
