Impact
STL (Sound Transmission Loss) is a decibel reduction based on
the vibration component
of sound transmission. This test was estimated – a partial
area of the test chamber’s floor was
floated using PlatFoam to mimic real world conditions. Not in
strict compliance with ASTM E492. |

Description
:
The Auralex SubDude(HD) is a 15" x 15" x
2.5" platform wrapped with ozite to fit any room
setting. Its purpose is to prevent sound from transmitting
through your subwoofer to surrounding surfaces. Subwoofers
create big vibrations (low frequencies) that you can
feel in the floor and in objects placed nearby. When
the source of the vibrations is coupled directly to
the floor it causes these objects to vibrate or resonate
– not only at the fundamental pitch the source
is creating but also at harmonic frequencies that
discolor the true sound from the source. Now you have
two (or more) objects vibrating, which creates an
acoustical problem called “secondary resonance”.
Note the graph of SubDude performance on a sample
concrete floor, the most noticeable effect is on harmonic
frequencies above 100 Hz. This is the harmonic range
above the fundamental the sub is recreating, allowing
you to hear a more true bass tone below 100 Hz by
eliminating upper harmonic resonances. This translates
to the listener as more accuracy in the low end, and
a cleaner (less muddy) crossover between the sub and
your full range LCR channels. The SubDude effectively
reduces secondary resonance by decoupling your subwoofer
from the floor so you hear your sub and not the vibration
of the other objects in your listening environment.
When speakers are tested in anechoic chambers, they
are isolated from objects around them that could introduce
resonance. With the SubDude, you can recreate a similar
scenario in your living room. Visit your local Auralex
dealer to hear a demo for yourself!
