"WitrynaAchieving a 3 dB increase in sound pressure needs twice the amplifier’s power. So if one speaker is 3 dB more sensitive than another, the less sensitive speaker will demand twice as much power to reach the same sound pressure level (on-axis) as its more sensitive counterpart. An increase of 6 dB is equivalent to twice the sound pressure. " - Is spl the same as db
