Survey of Manufacturers and
Here are some products that were sent to us for inclusion in this article.
Note that some acoustical room treatment materials (sound absorption,
diffusion, etc.) are flammable, and may have been treated to be flame
retardant by the manufacturers, but you need to confirm this yourself when
installing them, and decide whether they are suitable for use in your
situation. Remember also to be careful with the adhesives. They can be
flammable as well, and can be irritating to the respiratory system.

|The SonoFlat 2’ x 2’ x 2” panels are made of Auralex’s Studiofoam.
This panel has a smooth face and beveled edges. It is dense foam
which has some resistance when you squeeze it. There are not any
pores that are greater than 2-3 millimeters on the surface. The
panel has clean lines and good quality construction and is said to
be flame retardant. The panel is burgundy in color but is available
in a few other choices. Retail price for the SonoFlat panel is
$299.99 for a box of sixteen.
|The Elite B22 ProPanel is 2’x2’x1” has a smooth surface and
beveled edges. It is softer in the center than on the edges where it
is very rigid. The semi-course fabric which covers the absorption
material is pulled tightly across the surface and has no defects or
loose spots. The sample color is called garnet which is a deep
burgundy red. It is also available in a few other colors. This panel
retails for $64.99 per panel, or $99.99 per panel for the larger
2’x4’x1” model (Elite B24 Propanel).
|The SonoColumn is a 12”x6”x48” bass trap and is manufactured with
thick dense foam. This foam compresses very little when you squeeze
it. The edges are beveled to allow for corner placement and the
front is ridged. The traps are designed to be stacked on top of each
other for 8’ ceilings. Collars are available for these to create a
column look. They are available only in charcoal and retail for
$219.00 for a box of four.
|The CornerFill Cube is 12”x12”x12” and is used to fill trihedral
corners where bass traps come together. This cube is made of dense
foam like the foam in the bass trap. The sample cube is purple in
color but is available in many colors. These cubes retail for $39.00
for a package of two.
|The SubDude is a subwoofer isolator board. It is manufactured of a
board wrapped in charcoal fabric that sits atop two sections of very
stiff foam. In between these sections is a section of softer foam
wedges. A 50 pound subwoofer resting on top of this panel didn’t
push the foam all the way to the floor. The SubDude retails for
|The MoPad isolators are used for isolating energies from small
monitor speakers. They are made of stiff dense foam and are
separated into two sections of angled wedges. This allows for the
ability to angle the monitor eight degrees upwards or downwards. The
Mopads retail for $29.95 for a package of four pads that support two

|The room tune pack includes four Corner Tunes, two Echo Tunes, and
four Tune Strips. The sample kit included one of each of these
items. Each of these looks and feels like thin pillows made of light
burlap. One side is stiff, so there is probably a sheet of thin
vinyl or such sewn into the pillow. The other side is much softer to
the touch and suggests that they are filled with dense fiberglass
material. These would be used in the wall-to-wall corners of the
room to absorb bass frequencies. Retail price is $364.99 for the
pack of ten items.

|The LE MiniTrap is 19-1/2 inches by 4'-9" by 2-1/4 inches thick
and weighs ten pounds. These bass traps use a fiberglass material on
the exterior and are encased in a metal frame. Knocking on them
provides a dull thud, and I suspect there are multiple layers of
various materials inside. These are larger than standard foam traps,
and their build quality is exceptionally good. They can be mounted
on the walls or used with the stands shown in the picture. Retail
price for the LE MiniTrap is $219.99 each. The stand retails for
|The MondoTrap is RealTrap’s newest bass trap model. In appearance,
it looks like the LE MiniTrap except that it is two inches thicker
(pictured on the right). It is also 24 pounds heavier. Both the
MondoTrap and the MiniTrap are designed to have air space between
them and the wall corner which is intended to provide bass
absorption for both sides of the panel. Knocking on this model
presents the same dull thud, but a hollow sound makes it more
apparent that there is some space between any internal layers of
material. The build quality of this bass trap is excellent as well.
The MondoTrap retails for $279.99 each and can also be used with the
LE Style stand.
