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 89dB
in-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 ?Edited by Dayter - 1/15/13 at 1:30am
