why do you spike subwoofers to the floor? (1 Viewer)

[Ryan T]

Hi,
I was just looking through partsexpress.com and saw they had some really nice looking speaker spikes and they said they would improve the performance of subwoofers. Does anyone know how this works and if there really is a noticeable difference in sound quality. My room has thick carpet about 1" to 1-1/2" if that helps.

Ryan,
Capet acts as an acoustical dampening material and when your
sub or even your full range speakers float on top of the
carpet they are not acousticly tied into the hard sub-strate
of the floor. The spikes pierce down through the carpet and
allow vibrations to travel through the floor. In the case of
a sub it will help it transmit all the low frequencies that
it's capeable of putting out but your carpet might not be
allowing it to transmit.
