I’m going to show you how to protect your small speakers from big-powered amplifiers. If you connect small speakers to a powerful amplifier, then they will be destroyed by the amplifier. You will first of all feel a burning smell and they will stop working altogether.
But this does not mean that we use big power rated speakers with big-rated power amplifiers. There are special types of speakers like tweeters that do not come in big sizes. So how do these get connected? In the video below I explain how to do exactly that.
Filter capacitors
There are ceramic capacitors and electrolytic capacitors. The difference is that electrolytic capacitors have polarity. This means that they have a positive and negative leg. If you incorrectly connect them, they will blow up. But ceramic capacitors can be connected either way.
These capacitors are used to filter out unwanted frequencies and by doing so reduce the power transferred to the speaker. This is called filtering and its exactly what is used to make crossover units in loudspeakers.
