What does it mean when your subwoofer is stiff?

Updated on February 22, 2026
The Extra Stiff Suspension is simply a means by which a competitor can shove more power into a sub without the driver exceeding its mechanical limitations (you know when the voice coil becomes a projectile). The compliance of the suspension is not going to have a direct effect on the inductance of the sub.
Also question is, what happens when a subwoofer is underpowered?
Underpowering your subwoofer — Pop and Sizzle
Not giving it enough power just means that the music will sound weak and lack detail. The clipped signal tries to make the sub do things it's not designed to do, which leads to it tearing itself apart or overheating and burning out.
One may also ask, why did my subs stopped hitting hard? It could be a bad power wire, a bad RCA wire, a bad amp, a bad HU output, a bad voicecoil, etc.
Accordingly, what does sensitivity on a subwoofer mean?
Sensitivity is a measurement of how loud a speaker will get with a given amount of power. If you see a speaker rated at 90dB, that means that with 1 watt of power, it will produce 90dB of output when measured from 1 meter away.
What does a bad subwoofer sound like?

The higher the sensitivity rating of a speaker, the louder it will play with a certain amount of wattage. For example, some speakers have a sensitivity of around 81 dB or so. Anything below 84 dB is considered rather poor sensitivity. The sensitivity of 92 dB or higher is very good and should be sought after.What is a good SPL?
Speakers will sometimes come with a MAX SPL rating. SPL stands for Sound Pressure Level and is measured in dB (Decibels).
