Crux of the matter is can you hear the difference?
At these signal levels I seriously doubt it.
At higher signal levels maybe, but there's no data.
I don't understand your graphs. Both are labeled the same--18WU/8741T00. I would think, with a 17 db difference in the level of 2nd harmonic distortion, that a difference would be audible. Did you mean to say that the same speaker measures wildly different between samples?
Well, let's see......your 10 watt amp peaks at 20 watts; allowing for the average of 14db peak-to-RMS headroom (25:1), and your 83 db/1m/2.83v speaker, you are left with about 82 db listening level with no clipping. My, you certainly must live a QUIET life!!!
Well he's not the only one that does. My system has the capability to go really rather loud but I never listen that loud. Well maybe not never, occasionally I'll crank it for one track, but for normal listening? I doubt I even hit peaks of 95dB.
Copy/paste is very difficult for me as it seems
KSTR has already mentioned the correct speakers. Just point your mouse at them and it shows the speaker type of the graph.
What matters is how far below the original sound the distortion is and at 40Hz this is more than 35dB down for both speakers. If your listing to music it is very likely that these distortions will be masked by the original sound.
