Ultimate Bass Challenge Vol. 3 * by Bass Quake (CD, Apr-2005, Neurodisc Records)

This CD is just what it says it is. There are some good test tracks for your subs, some are even not that bad as songs of their own. I have to turn my bass down when I pop it in because the subs are louder than other CDs. If you want to see your subs move, this CD will do it. I still want one with all the test tones in Hz, this does not have those it is more like different songs with differing ranges of bass in each. Some clear, some like thunder, some lower and some higher, etc. It is great if you are trying different subs and want to compare them like I was...or if you just want to give them a workout.
