Hmmm.. So , according to these measurements , my Paradigm
MilleniaOne satellite speakers would suffer in reaching the
105dB reference SPL at 4 meters distance .
Here : It's sensitivity is rated at
89dBin-room , but most reviewers measure it at
88dB approximately (Paradigm overrated) .
So , 88dB powered by 1 watt , gives
108 dB (adding 20dB) powered y 100 watts , which is the maximum power handling of the speaker , and the average power output of my amp as well .
But this is at just 1 meter apart , and according to the
Inverse square root law , doubling the distance form the speaker looses 6dB loudness.
And since the listening distance is 4 meters , then this 108dB is gonna be
102dB (at 2 meters apart) , and
96dB (at 4 meters apart which is my position) ..
The equation does not stop at this point , as all these calculations are made for just one (mono) speaker , but by adding the other front channel as working in stereo mode , would yield +3dB increase in loudness , therefore the final subjective Loudness level would e 99dB , which is far away from reaching the reference benchmark .
So , These MilleniaOne's won't have the
dynamic headroom to meet most of the musical spikes and sound effects' climaxes in today tracks .
Am I right ? Or something missing ? or these numbers are just for sustained volume , and the spikes can be held easily even at higher levels unclipped ?
