Corner Loaded Bass Trap
The tri-corner of a room acts to transform and compress all of the acoustic energy in a sound wave into
pure pressure fluctuations. TubeTraps are designed to take full
advantage of the acoustic pressure zones created in the corners of a
room. They convert the pressure changes into air movement within the
dense walls of the TubeTrap. Through regulated friction in the walls of
the TubeTrap, energy is damped out of the wave.
Because of how it works, the
TubeTrap is known as a "pressure zone bass trap." The diameter of the
TubeTrap, not the length determines the low frequency cutoff. Only
TubeTraps have built-in diffusive reflection panels to maintain
ambience control. TubeTraps work best in areas where there is heavy
bass, such as the corners of the room.
When low frequency sound
is injected into a room, the
waves reflect back and forth. At certain frequencies, the reflection
patterns begin to overlap and lock into a synchronized condition with
each other to produce standing waves. Whenever this pattern overlaps
the speakers we get "room boom", an overpowering emphasis by the
room/speaker arrangement to play only a few, very strong bass notes.
Nothing can actually get rid of
room modes, short of removing the room entirely. But adding bass traps
will even out the bass response and improve transient attacks and
decay. Although every mode has a unique pattern of pressure zones
distributed throughout the room, all modes have pressure zones in the
tri-corners. ASC is the pioneer of corner loaded bass traps, and the
TubeTrap remains the unsurpassed upgrade for all high performance audio
When a woofer is located
near a wall, its freefield frequency response becomes distorted. The
nearby reflection drives a pressure wave back over the speaker cone.
Walls, floor and corner reflections produce 5 to 20ms delay signals
that mix with the direct signal at the driver to induce comb filtering
effects into the bass range of the speaker and as well, side lobe
A TubeTrap located at each of
these reflection points will reduce the strength of the reflection.
This reduces the comb filtering and side-lobing effects in the bass
range. But not all wall reflections are bad. Speakers located near
walls deliver better deep bass. Our boundary conditioning Traps are
bandwidth limited to allow them to defeat comb filtering and beaming
effects but not at the expense of wall loading in the deep bass range.
Diffusive strips in the Traps are oriented behind the speakers to
better develop the ambience.
TubeTraps can also be used in the
open, close coupled to speakers in order to improve their performance.
By stacking TubeTraps to expand the effective size of the speaker
baffle board, the effect of increased bass directivity and efficiency
is achieved. This works with sealed, front ported or dipole speakers,
flown or stage mains, hi-fi, studio monitors, portable PA and nightclub
In addition, the TubeTraps can be
stacked in a forward stepped array that casts an acoustic shadow to the
side of the speakers. The diffusive strips of the TubeTraps are
oriented away from the front of the speaker for color-free horn
loading. This shadowing technique protects on-stage mics from feedback,
small room listening from side wall reflections and halls from
