    Could these speakers be underpowered?

    Would the speakers whose stats I outlined below be underpowered by this receiver?

    Receiver:YAMAHA RX-V373BL
    Rated Output Power (8 ohms, 1 kHz, 0.9 % THD, 1 ch driven): 100 W/ch Rated Output Power (8 ohms, 1 kHz, 0.9 % THD, 2 ch driven): 85 W/ch Dynamic Power/Ch (Front L/R, 8/6/4/2 ohms) 110/130/160/180 W

    Speakers: PSB - G-Design GB1
    Frequency Response: Lf Cutoff -10 dB, 32 Hz; (-6 dB) 38 - 23,000 Hz
    Sensitivity (1w (2.83V) @ 1m, IEC-filtered Pink Noise, C-weighted): Anechoic Chamber, 86 dB; Typical Listening Room, 88 dB
    Impedance: Nominal, 6 Ohms; Minimum, 4 Ohms
    Input Power (RMS,Clipping < 10% of the Time): Recommended, 15-200 Watts; Program, 100 Watts
    Crossover: 2,200 Hz, B3
    Internal Volume Design Type: 0.50 cu

    If you listen to normal to moderately loud listening levels in a small to medium sized room then you should be fine.

    Speaker wattage ratings are pretty much useless and worthless.

    If you must be concerned about wattage ratings the rating to be concerned about is the speakers program rating. Note, it says 100 Watts. This is close enough to the receivers 85WPC rating as to be almost equal.

    BTW, the difference (in real power) between 85 Watts and 100 Watts in a receiver is negligable (<2dB).

    Check this:

    Impedance: Nominal, 6 Ohms; Minimum, 4 Ohms
    excellent. These are build for low-power tube amps.

    Your receiver is rated at 100 / 8 Ohms; when impedance is halved, a stable amp should double its output (as for instance Krell does).
    Your amp does not, it's not even close (check Dynamic Power/Ch (Front L/R, 8/6/4/2 ohms) 110/130/160/180 W). But then again it won't have to, as your impedance decreases by 1/3 max. That is a very easy load. No problem at all.
