Headroom Notes
The 60 W / 120 W pair carries no distortion figure, no bandwidth and no statement of how many channels were driven. The only distortion number WiiM publishes for this unit - 0.0025 % - is measured at 5 W, which is a linearity figure and says nothing about the power rating. The amplifier section is a TPA3255 fed from an external brick, so the ceiling is set by the supply that happens to be in the box.
Thermal Behavior
WiiM does state a minimum load, which most streaming amplifiers do not - but the row that states it also says '2 pairs 8 ohms in parallel', and two 8-ohm pairs in parallel is 4 ohms, not 2.67. Treat 2.67 as the number printed, not as a tested guarantee for a speaker whose impedance dips there.
Was im Datenblatt tatsächlich steht
Wörtlich von der Herstellerseite zitiert, mit dem Datum der Prüfung. Wir behaupten das Gedruckte, nicht die Absicht dahinter.
«Speaker Output: 8 ohms, 6 ohms, 4 ohms / 2 pairs 8 ohms in parallel / Minimum Impedance 2.67 ohms»
One row states two different lowest loads. Two pairs of 8-ohm speakers wired in parallel present 4 ohms, not 2.67; 2.67 ohms is what three 8-ohm loads in parallel - or an 8-ohm and a 4-ohm speaker together - would present. The wiring case the row describes and the minimum the row names do not match.
geprüft am 5.8.2026«Power Output: 60 Watts/channel at 8 ohms; 120 Watts/channel at 4 ohms — THD+N (Analog Out): -92dB (0.0025%) at 5W»
The power figures are given without a distortion limit, without a frequency band and without saying whether one or both channels were driven. The only distortion figure on the sheet is taken at 5 W, so it cannot be read as the condition under which 60 W or 120 W was reached. A number stated this way is not comparable with a full-band, two-channels-driven rating.
