I've heard people talk about speed but I don't know what they're talking about but would like to understand it.
So do you need music to test the speed of your drivers?
Try this: Charly Antolini, "Knockout 2000." Strong drum and bass of real instruments. All instrumental.
Not my cup of tea for pleasure listening but it's well recorded and tests the low end without resorting to hearing pipe organ.
