COMMENTS
0.75
Not a lot of deep bass but O.K. for most listeners
1.5
O.K. low end but tons of power handling - JAM ON IT!
2.0
Very natural low frequency performance with good transient response
0.75
A little boomy due to small box
1.5
HIT IT HARD! (..as long as you don't hit it with lots of subsonic frequencies)
2.0
Really pleasant deep bass with good tonal quality
2.0
Somewhat "one-note" performance due to small box
2.5
Narrow bandwidth but crying out for a serious "beating"
3.5
Super low frequency response but trade off for lower audio output
