Ohm’s Law states that voltage V is directly proportional with the current I flowing in a circuit and resistance R Electrical energy is a product of power and time. Energy = P x t If power P is measured in kilowatts and time t in hours then the unit of energy in kilowatt-hour ( or …read more
To power a system of numerous low-powered loudspeakers from a single amplifier you need to use distributed lines, often called constant-voltage lines. This method connects speakers in parallel across a pair of wires and they can be individually adjusted for their output power. Constant-voltage lines, are categorized by their maximum RMS voltage: 25-, 70-, 100-, …read more
Bigger the speaker the bigger inertia of the cone/voice-coil assembly is. That means one thing: due to the inertia, the cone assembly overshoots the resting point and thus generates unwanted EMF ( electromagnetic force ) that produces a current that feeds back in to the audio amp. And that’s a cause of distortions… Therefore , the …read more
