I've gone and overlayed the M50 and M60 frequency response charts as semi transparent layers in Photoshop. From a comparison of the two, I noticed the following things:
1. (M50 is less sensitive) The M50 isn't as sensitive (db) as the M60 between the 40-400Hz range, you'd have to turn the turn volume knob up a little higher while using the M50s to to reach the same output as the M60;
2. (M50 is brighter) Because the M50 lags M60's sensitivity until around the 400Hz mark, the M50 would seem to have a subtle inclination across the chart, whereas the M60 would appear to be more flatter (ignoring dips and peaks) overall - suggesting the M50's highs would appear to be mor pronounced relative to its lows.
3. (M50 has better bass extension) Even though the M50 might seem a bit brighter (my assumption from above) than the M50 while playing at a similar volume, it's the M50 that will play bass audibly into lower frequencies as its rolloff starting at 90Hz is a LOT slower.
Comments/Corrections anybody?
