[QUOTE="Mitch Miller, post: 137846, member: 2673"] Re: dB calculations Am I to understand that 10 watts into a 10" speaker will produce less dbSPL than the same 10 watts into a 100" speaker? Aside from physical differences that result in forces such as friction and larger mass, 10W should produce the same amount of SPL in any speaker (efficiency not withstanding). I think there's a whole lotta confusion regarding units of measure. dB SPL is not o let the electrical power being consumed by the driver, but also the mechanical resistance of the cone, cabinet design, and environmental factors such as other drivers nearby. I think a pure theoretical world, double the power is an additional 3 dB, regardless of the units. In the real world, though, that may result in more than +3 dB SPL. Yeah? [/QUOTE]
