Powered speakers do not need an amplifier. They have an amplifier already installed in them which is why they are called powered speakers to begin with. Depending on the speakers input options, you can hook them up to different audio sources without the need for a separate amplifier.
Is amplifier bad for speaker?
Amplifiers can be too powerful for speakers. Speakers are limited by the electrical energy that they can convert into audio. As a general rule, if the amplifier produces more electrical energy than the speakers can handle, it may cause distortion or clipping, but damage is unlikely.
How do I choose an amplifier for my speakers?
Generally you should pick an amplifier that can deliver power equal to twice the speakers program/continuous power rating. This means that a speaker with a “nominal impedance” of 8 ohms and a program rating of 350 watts will require an amplifier that can produce 700 watts into an 8 ohm load.
Can loud sound damage speakers?
Playing music/audio too loud may cause damage to speakers due to excess heat in the drivers or even mechanical failure of the driver suspension. Speakers have power ratings that, when exceeded (by increasing the amplifier/volume control), will burn/melt the driver coil and damage the speaker.
How much do good speakers cost?
If you are in an average sized, untreated room and listening to music for entertainment, your best bet will be in the $300-$1,200 range. The higher you get within that range, you will generally find better results, but a higher price doesnt guarantee quality.
