I have found on youtube.com a perfect compilation for subwoofer testing.
There are six guys saying that this is six different songs:
Beat Dominator – Bass…. Can U Hear Me?
nó
Beat Dominator – Feel the Bass
nó
Bass Mekanik – can you hear me
nó
DJ magic mike – feel the bass 3
nó
Beat Dominator – Beat the bass, Can you hear me?
nó
Dj Magic Mike – bigbass woofer test.
that sound is good
