Many people are concerned about the possibility of "blowing out" their speakers. This occurs when there is too much input entering the speaker. People who have expensive car systems capable of huge amounts of output are most susceptible, and nobody wants to ruin a brand-new, costly speaker system! This situation, and the unattractive, distinctive buzzing sound caused by a blown speaker, can be avoided by utilizing the following tips.
First, check your speaker's impedance. A speaker's impedance is the amount of electrical resistance it presents against the current flowing from your amplifier or powered output. Make sure the impedance match is appropriate between the two. Most speakers have an impedance of 8-ohm, but there are also many 4-ohm speakers out there. Consult your manufacture's manual to know your speaker's impedance and plan accordingly.
Second, check the speaker's power. Your speaker's power is how much input it can withstand from an amplifier or power source. If your speaker power is low, you will need to search for an amplifier with less power. It is tempting to try and violate this tip to save money, but you should not. Your speakers may be able to handle the increased power for a short time, but they will ultimately become damaged and need to be replaced.
Third, make sure your amplifier has lower power than your speaker. While you can sometimes get away with the amplifier and speaker power matching, it is best to set up your system on the side of caution and make sure there is never too much power going into your speaker. Sometimes a sudden increase of volume from an amplifier can overwhelm a speaker, even if the power matches. This can occur most often when the volume is turned up on an already high amount of input. You will be able to get away with sudden volume increases to your favorite songs if you make sure your amplifier has a lower power than your speaker.
Finally, make sure you have the same impedance on your amplifier and your speaker. Once again, it is crucial to make sure these two numbers are congruent. If you’re uncertain of whether or not your system fits this criterion, ask a professional.
If you ignore these tips and blow out your speaker anyway, luckily there are companies that sell replacement parts such as recone kits, diaphragms, and more. Of course, it’s best to avoid this scenario altogether.
"Blowing out" your speakers is very real risk that can cause substantial damage to your equipment, not to mention some serious irritation and financial setback. Following the above tips will help minimize this risk and help your speakers last for many great tunes to come.
