Can the input be smaller than the output?
Assuming you wanted an answer under energy and thermodynamics topic: No output power can’t be greater than input power? There is no system whose efficiency can be more than 100%. Power which is a form of energy, the output will be will be less than the input power always.
What is a good output power for speakers?
If you like loud uncompressed music and your speakers are 90dB efficient, 200 Watts is likely plenty of power for you. If you only listen to light classical, jazz and don’t expect them to rock the house, 50 Watts is adequate. Higher efficiency speakers, like horns, take very few Watts.
What is the difference between power output and power input?
Input refers to the amount of energy put into a device, and output refers to the amount of energy that comes out. For example, a light bulb’s input energy is the form of electrical energy, and its output energy is in the form of light and heat.
Which is more powerful an amp or a speaker?
The speakers should be rated for the same or MORE power than the amp, otherwise you risk overdriving them which can easily damage them.
What is the maximum power of my speakers?
Mine goes from -100 DB (approx) to +13 DB. If you were to run 20 watts continuous in my listening room with my speakers of average sensitivity supported by a powered sub, the loud volume would drive you out of the room. it would literally hurt. 40 watts would be ridiculous. I wouldn’t worry about it at all.
Why does the output of an amplifier go higher?
As with a loudspeaker and amplifier, output can go higher as the duration of the effort gets shorter. With a cyclist, the anaerobic threshold is where demand for oxygen exceeds what the athlete can take in and process, and lactic acid accumulates in the muscles faster than it can be dissipated.
Why are power ratings different for different speakers?
Another potential area of confusion. Any power rating you see should be given into a particular load – or impedance. Therefore, if an amplifier rating provides 100 watts of RMS power into 8-ohm speakers, then the RMS power it provides will be different if you attach 6-ohm speakers.
