Do dented dust cap affect sound?

Do dented dust cap affect sound?

When it comes to speakers without grills, people usually punch or push a small dent on a speaker’s dust cap. The dent doesn’t actually affect the speaker’s performance but rather it becomes eyesore, dents make speakers look ugly.

What does the dust cap on a speaker do?

The dust cap (also known as dust dome, or dome) is a gently curved dome mounted either in concave or convex orientation over the central hole of most loudspeaker diaphragms. It protects the inner mechanics (such as the pole pieces and the voice coil) from small particles (which can cause rubs) and other contamination.

Does a ripped subwoofer work?

As long as the cone and rubber surround structure are intact and structurally stable you will get your bass. Cover the hole with some light, stiff tape and any leakage effect will go away entirely.

Is it bad to touch speaker cones?

If you touch the cone during operation you are likely not to do this symmetrically, so the movement isn’t straight any more and the windings of the coil can rub against the magnet and possibly get damaged or deteriorated. Not generally, as long as little force is used.

Can you patch a hole in a subwoofer?

Depending on the severity of the cut, you may need some other scaffolding material (aside from RTV silicone) to enclose the hole. In this case, all we need to do is cover up the tear with RTV silicone in order to make the subwoofer almost as good as new — functionally, at least.

What is the life of speakers?

Most speakers last more than 20 years, but some can last a lifetime. It depends on many factors, the most important among which are the type of the speakers and their maintenance.

What is the purpose of a dust cap on a speaker?

Some dust caps are indeed vented to provide an air flow over the voice coil assembly, particularily large high-wattage PA drivers. The center portion of the cone (typically formed by the dust cap) is also where the higher frequencies are produced as a matter of physics.

What happens if you put a dust cap on a driver?

So without the dust cap, there would be hole open to the back of the driver structure. We want an airtight situation and the dust cover provides that. This is one good reason why a hole in a dust cap creates an air leak and is not a good idea.

Does the shape of the dust cap affect the frequency response?

The direction of the movement is modified by the particular location of the “testing” point on the cone, so the differing shapes of the dust cap have an effect on the frequency response.

Does a bigger dust cap make a difference?

Prof Leach has pointed out that a bigger dust cap gives the impression that it is covering up a former of larger diameter, even if the former is small. I have a pair of drivers with the wizzer cone. I can’t say it doesn’t work to extend high frequency response, but it seems more an act of desperation.
