Physically inspect the speaker.
A blown speaker can have damage that can be heard with some mechanical movement. If you gently tap on the cone of the speaker it should have a firm drum like sound. If you hear a rattling sound (like a loose snare drum), this is an indicator of a bad speaker.
Turn on your vehicle’s radio, and turn up the volume. Listen for any distortion in sound quality, such as a hissing sound. If a speaker is blown, the distortion should increase as you turn up the volume. Listen to each of your speakers to determine which of them are blown.
Too much bass can cause the speaker cones to move excessively beyond its limits — a situation known as over excursion. Over time the cones will deform and eventually break. Also, an extremely loud bass can easily damage midrange speakers because they are not designed to play low frequencies.
Measuring them with a multimeter will often give you results that could make you think the speaker is bad. The best way to test them is to QUIETLY play a signal through them, listen to it, then see if it produces sound. If it does not, or sounds bad, the speaker needs replacing.
For a 4 ohm speaker, it should read between 2 and 4 ohms on a meter. For a 8 ohm speaker, it should read between 4 and 8 ohms on a meter. For a 16 ohm speaker, it should read between 8 and 16 ohms on a meter.
The bones in your ear translate those vibrations into nerve signals, which your brain interprets as sounds. But other body parts can vibrate, too, including your chest. For most of us, this is nothing to worry about. Unless you have a serious heart condition, the pounding bass shouldn’t affect your heart muscle.
As a general rule, speakers and subwoofers should be able to withstand bass boost. The only time that there is a risk of damage is if the SPL is extremely high. At exceedingly high volumes, boosting the bass could cause damage. … Bass boost shouldn’t pose any issues if the volume is kept to a sensible level.
You just need to be really careful that it isn’t actually too loud. It is possible to damage your hearing without feeling any pain when you are using selective frequencies of sound at high intensity.
The most common aural indication of a blown speaker is an unpleasant buzzing or scratching sound, by itself or roughly at the pitch of the note the speaker is attempting to reproduce. Or there could be no sound at all.
To tell if the speaker is blown or not without taking it apart is really easy. All you have to do is take a 9 volt battery and touch it to the wires. If it makes scratching noises its good. If it makes no sound at all its blown.
The increase in movement causes heat inside the speaker. If the speaker components are poor quality, then heat damage may occur. Ultimately this leads to distortion. When your speaker is playing at low levels, damage may not be noticeable, but the higher the volume, the more evident this becomes.
Your 16 ohm speakers will have one quite predictable effect – if the amplifier is rated at say 100W into 8 ohms, it will only deliver approximately 50W into 16 ohms.
Originally Answered: Can I use two 4 ohm speakers with on an 8 ohm amplifier? Yes you can. As long as you Don’t play it at too high of a volume. Basically if you play it too loud the speaker will draw too much current and you might blow the amplifier.
Generally, the reading given by an ohmmeter will be about 2/3 to 3/4 of the impedance of the speaker. So, a 4 ohm speaker will typically measure about 2.5 – 3 ohms, and an 8 ohm speaker will typically read about 5-6 ohms, while a 16 ohm speaker will measure around 12 ohms.
There is a variety of issues that can occur with speaker voice coils, and sometimes it is possible to repair them. … Occasionally on smaller speakers with no adjustments it can be possible to repair them by easing them back into the centre. Gently hold the cone – remember it is made of paper and can damage easily.
Ensure the speaker wires are properly connected to both the speakers and stereo receiver. Turn off any nearby electronic devices that may be interfering with the speaker sound. Move the speaker wires away from any electrical cords. If the issue is still unresolved, reset the receiver to the factory default settings.
Every speaker in a car audio system dying at once is very unlikely without some serious abuse, like cranking the volume high enough to blow the speakers out. When all of the speakers in a car audio system all stop working at once, the problem is usually in the head unit, in the amp, or in the wiring.
NOTE: Some A/V receivers have a Speaker A and Speaker B switch on the front panel of the unit. The Speaker A output is used for the speakers in the main room while the Speaker B output is for a second pair of speakers in another room (garage or patio, etc.).
In recent years, experts have discovered that loud noise can hurt more than your ears. “It can damage the delicate nerve endings that transfer the electrical information from the hair cells [inside your ear] to your brain, potentially causing inflammatory reactions within the brain itself,” says Kim.
Undoubtedly. Turn up the bass, and the high-pressure sound waves can literally knock the wind out of you, causing your lungs to collapse, doctors reported this week. … One man suffered from the condition, also known as pneumothorax, while driving.
Distinguished. soundguruman : No, bass does not damage hearing like high frequencies. The small diaphragm in your ear drum is not large enough to respond to bass, like it can respond to high frequencies.
Low frequencies (relative to the driver in question) can often cause failure because, for a given sound power output, lower frequencies require greater cone excursion. If excursion becomes so great that the voice coil actually leaves the magnetic gap, a magnetic short is formed and lots of heat is produced.
As you can see, there can be different degrees of hearing loss at different frequencies. It is most common to see poorer hearing in the high frequencies (treble) than in the low frequencies (bass).
