Can too much bass damage speakers?

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.

Can you test a speaker with a multimeter?

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.

What does loud bass do to your body?

Can low frequency damage speakers?

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.

What is LPF on AMP?

As we discussed earlier in this article, subwoofer amps typically use LPF (low pass frequency) filters to block high frequencies that should be playing through your speakers. A subsonic filter will attenuate frequencies so low that your subwoofer cannot reproduce them OR that humans are incapable of hearing.
