Power needed
60–945 W
per channel, into 8 ohms
To hit 95 dB peaks at 3 m from a pair of McIntosh LCR80, you need at least 60 W a channel. Anything from about 120 W to 945 W a channel is comfortable; past that, more watts stop buying you anything.

- 95 dB target at the seat
- +4.8 dB for 3.0 m of distance
- -3 dB for a stereo pair
- -79.0 dB effective sensitivity
- 2 dB allowed for optimistic published sensitivity
- Published sensitivity 81 dB, used as 79.0 dB per watt.
Rotel A14 MKII with the McIntosh LCR80
Workable with care
Just barely enough (1 dB of headroom). Fine at normal volume, no reserve for peaks.
Rated down to 4 ohms, comfortable with an 8 ohm speaker.
Power nearly doubles into 4 ohms (80 W to 150 W) - a stiff supply that copes with hard loads.

61 power amplifiers that would also drive them
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 McIntosh LCR80 specs.
