Question about svs comparison chart. (1 Viewer)

[Sheldon C]

On the chart that compares the three models of subs it has the numbers on the left in db that range from -10 to -60. What do these numbers stand for? I know they refer to how loud the sub goes, I just have no point of reference. I assume that they don't mean how many decibles below reference because that wouldn't be very loud.

It's just a relative indicator for output. You can get an idea of the smoothness and extension each model is capable of. Max output depends on several other factors.
