Question 1

How many watts is good for speakers?

Accepted Answer

The short answer is - the more, the merrier - especially if you crave high volume, have wild parties, or a huge room. That being said, 50 watts will be more than enough for most people. If you only listen to light music and don’t expect them to rock the house, 50 watts is adequate. But if you like loud uncompressed music and your speakers are 90dB efficient, 200 watts is likely plenty of power for you. However, keep in mind that watts come cheaply nowadays, so it is sound quality that you should care more about. Even a low-watt speaker can produce truly spectacular sound.

Question 2

Can specific sounds damage speakers?

Accepted Answer

Playing certain amplitudes and frequencies on speakers that cannot hear them, can indeed damage them. Boosted bass makes the speaker move back and forth. And if that moving is too much for the speaker to handle, it may rip. On the other end, boosted frequencies may cause the tweeter to overheat. However, the best speakers from reputed brands are built to handle any type of sound. So your speaker should remain safe from damage, provided you use the speakers as advised in the user manual.

Question 3

What is a good dB for speakers?

Accepted Answer

On average, speakers come with a sensitivity of around 87dB to 88dB. A speaker sensitivity rating of over 90 dB is considered excellent. To put things into perspective, a train siren produces around 90dB when you are a few hundred feet away, while a loud music concert is about 115dB. A jet engine would produce about 140dB. However, speaker sensitivity measurements below 84 dB are relatively poor. So those speakers with 92 dB or higher are worth investing in if you want a loud and efficient speaker.
