Power needed
38–600 W
per channel, into 4 ohms
To hit 95 dB peaks at 3 m from a pair of Magnepan 1.7x, you need at least 38 W a channel. Anything from about 75 W to 600 W a channel is comfortable; past that, more watts stop buying you anything.

Listed separately because they are not a complete system: a power amplifier has no volume control and no inputs to speak of, so you need a preamplifier or a streaming preamp as well. Worth it if you already own one, or if you want to buy the two halves separately.

Sensitivity and impedance figures are the manufacturer's own. We read sensitivity as dB at 2.83 V/1 m and take 2 dB off it, because published figures run high. Treat the result as a well-founded starting point, not a measurement. Full Magnepan 1.7x specs.
