Power needed
25–120 W
per channel, into 6 ohms
To hit 95 dB peaks at 3 m from a pair of Yamaha NS-600A, you need at least 25 W a channel. More than 120 W is wasted here - that is all Yamaha rates the speaker to take.
Show the working
- 95 dB target at the seat
- +4.8 dB for 3.0 m of distance
- -3 dB for a stereo pair
- -82.8 dB effective sensitivity
- 1.2 dB taken off to convert the 6 ohm 2.83V rating to dB per watt
- 2 dB allowed for optimistic published sensitivity
- Published sensitivity 86 dB, used as 82.8 dB per watt.
Buchardt I150 with the Yamaha NS-600A
Workable with care
10 dB of headroom over what this speaker needs - peaks stay clean. Well above the 120 W the maker rates the speaker for, so keep an eye on the volume knob.
Rated down to 4 ohms, comfortable with a 6 ohm speaker that dips to 3.6.
Power nearly doubles into 4 ohms (150 W to 300 W) - a stiff supply that copes with hard loads.

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 Yamaha NS-600A specs.
