Why does my stereo sound bad when the volume is low but extremely good when the volume is high?

Answer 1

Most speaker drivers work on the 'piston' principle, That is, the signal from the amp activates the speaker magnets which push and pull the cones to create sound.

At low volumes, the cones don't respond very much, so don't reproduce the sound very well. As the volume increases, the cones are more active and produce a better sound. Pushing the volume too far, however, will cause the cones to 'bottom out' and distort the sound.

Most sound systems have a 'sweet spot', where the volume is just right to give you the sound you want.

Answer 2

At low input levels, the driver of a speaker doesn't move much , due to the signal not being strong enough to move the mass of the driver.The driver struggles to move quickly enough to reproduce the signal, and therefore it does not couple well with the air.
The tweeter is quite light and reproduces frequencies with shorter wavelengths, and as such at low levels it is more responisve in comparison to the driver.

Basically the ideal operation condition of an audio system is an equal straight line..often reffered to as a linear response. The principle here is that the unit responds equally to all frequncies at all volumes. This isn't possible though...for many, many reasons. But basically bass drivers underperform until the input is driven hard enough to be effeicient and linear in respect to the program material it is being asked to reproduce. This is why you find certain types of music can sound ok at low volumes.

Answer 3

sound nob has gone bad, it needs cleaning if you handle manually, if it is through remote then take to the dealer for proper maintenance.

Answer 4

mismatched speakers to head unit
