OVERVIEW:
US Enclosure uses a US-based 400,000 Square Foot production facility with capability of over
2,000,000 loudspeaker enclosures per year.
As OEM loudspeaker
designers/manufacturers,
we understand loudspeaker
manufacturing requirements.
We developed a unique
group of loudspeaker cabinet materials
after years of R&D.
We developed a multi-layer composite material using up to 6 different
components.
Our materials will cause
box-shaped loudspeakers sound better to the end-user.
US Enclosure
cabinets
can be mass manufactured into any curved, non-diffracting shape
avoiding acoustically damaging transitions
( edges, slots
)
in the shape of the loudspeaker enclosure which behave
as acoustical sources.
Our enclosures
can have twice the mass of either
an MDF or Baltic
Birch based cabinet.
Our
Proprietary Cabinet Wall Materials, called Multi-Modulus
and
CBL-- Constrained Boundary-Layer are specifically designed
for Loudspeaker Cabinets.
We
Control:

Factors to match your drivers.
We provide Class-A
finishes for our OEM products.
Unlimited
colors and Class A Mirror Finishes are available with control over
sheen-gloss levels, color, and surface texture.
Our materials
are useful wherever higher sound clarity is required... from cell telephones to recording studio monitors to headphones to
home loudspeaker systems to concert reinforcement.
US Enclosure
Design assists with careful design of a curved internal shape to
nearly eliminate the @ 50
db reflective bleed-through through the loudspeaker cones from the interior of
the loudspeaker enclosure.
OUR
manufacturing process is the BEST ALTERNATIVE for Loudspeaker
Production...
... because we
can even manufacture any shape including Box Shapes using walls denser than
MDF or Plywood. Our understanding of the physics and acoustics of
Loudspeaker design is proven by commercial practice.
QUALITY-
Sample Cabinets have been stored in a metal wall shed for 16
years exposed
to 100 degree+ temp. extremes and the walls are perfect
Most importantly, we
also have
the Experience to properly execute
our clients
exacting & demanding mass-manufacturing
requirements.
|
| From 1990 through
today, we perform research and
development on loudspeaker
lines
using our unique loudspeaker enclosure materials.
And until 2002 we had our own line
of
loudspeakers; we understand the OEM
loudspeaker industry. When we became 100%
OEM
Subcontractor, we already had located
the best subcontractors to manufacture our
materials
for you.
When contracted by your company, we apply intensive R&D and exhaustive
testing to
finalize the process to
beat your expectations, with results we both can believe in and
are both proud of.
In 1990, we approached the problem by looking at the driver housing
as...
(1) dealing with
the sonic back wave launched by the driver into the enclosure,
and
(2) allowing
cost-effective OEM manufacturing of cabinet shapes that will minimize
external
diffraction and distortion.
The two major drawbacks of using an MDF or Baltic Birch box is that MDF can
not be
made into non diffracting shapes and also exhibits a series of strong
resonance's in the
250 - 750Hz region as well as an acoustic window in the
14,000HZ range.
Our enclosure materials works with stuffing by efficiently
converting back wave sound
energy into heat by using viscoelastic properties and laminated
compounds, dissipated
evenly throughout the outer layers of the cabinet.
This process is further assisted by the
available non-symmetrical internal
shape and wall thickness, which also defeats internal
diffraction and sound
wave reflections back through the loudspeaker cones.
Finishes:
Our most popular finish is our
High Gloss Piano Black,
with a stunning
mirror-like finish. We can at your request provide
any finish you
specify.
We believe all loudspeaker cabinets are active components of a
sound system, and
important to the overall sound
as the cabinet is an active energy conversion
system.
Its job is to contain and convert energy.
It must deal with the back-wave
produced by
the
drivers it houses. Recalling that the back-wave
inside the cabinet has
just as much
force the
sound emanating into the room will both reflect through the
loudspeaker cones
as well as
energize the cabinet and cause
resonance.
In order to create an acoustically inert cabinet that is also non diffracting, and,
cost-effective for an OEM, one must apply creative engineering solutions to
supply the
best product possible then provide our clients with a 24/7
level of backup and service.

Technology and
Capabilities:
Quantizing Noise , we lower it in loudspeaker systems
better than anyone.
Our
technology is useful wherever higher sound clarity is
required, from cell-telephones to recording studio monitors to headphones to
home loudspeaker systems to concert reinforcement.
The spherical, ovoid and parabolic cabinet shapes created by
US Enclosure’s
Design
Bureau
simply reduce exterior
& interior wall diffraction / reflection effects.
The
cabinet THD can be reduced from 10% common for current cabinets
near electronic levels.
Your products will have higher
sales better because your products will "sound better" to the
end-user.
As Important...
our
Proprietary Wall
Materials, called Multi-Modulus,
unlike any other loudspeaker enclosure manufacturing material,
is specifically designed to absorb
internal sound
waves. This is Not an Idle Claim. The finish, strength, and vibration-absorption
characteristics of our products are comparable to or surpass the
benefits of any other loudspeaker cabinet on the market. And
most Importantly. Multi-Modulus is specially suited to the
challenges of making loudspeaker enclosures of Any
Shape using cabinet materials that surpass the acoustic qualities of
highest-grade wood-- at a cost lower of a wood loudspeaker
enclosure and also with a finish quality as good as any
wood
material.
We use all the required engineering
elements-- constrained boundary layer, etc. via a single-piece,
multi-layer, thick-wall enclosure with high finish grades with Complete
Control over all desirable
characteristics.
Unlimited
colors and finishes are available with our
well-proven proprietary manufacturing methodology and its technology
system and inherent production flexibility is designed into the
equipment. Product performance as viewed from a sound-and-look perspective
will be Equal To or Higher Than to your current cabinets and are
surprisingly cost-effective compared to your current enclosures.
Our method truly has the potential
to dramatically alter the "look" in the loudspeaker industry and to
increase your sales, contact us.
OUR ENCLOSURE
MATERIALS
US Enclosure
offers the only loudspeaker enclosure material specifically designed for
loudspeaker enclosures which can be made into Any Shape-- from Box to Sphere. Any
Application.
|
This
Technology allows the manufacture of loudspeaker enclosure shapes following
the Maxim...
Form Follows Function
without
compromising cabinet quality & with a reasonable manufacturing cost.
|
.
The elements we use are simple, effective and Fully Tested.
Not only does our wall-materials technology surpass the sound quality of wood
enclosures, the manufacturing cost is practically the same as that of wooden
box enclosures.
Unlike any other decent cabinet material, our wall materials can be mass
manufactured into any curved shape... finally allowing a loudspeaker
manufacturer to avoid acoustically-damaging transitions ( e.g. edges, slots ),
in the shape of the loudspeaker enclosure. These transitions themselves behave
as acoustical sources. Arrivals from these features always follow the primary
wave in time and are often reversed in polarity. And with careful design of
the internal shape, our enclosures can reduce or virtually eliminate the @ 50
db reflective bleed-through through the loudspeaker cones from the interior of
the loudspeaker enclosure.
Our BEST
Mass Manufactured Loudspeaker-Wall Materials use the
same chemical enhancements used in Satellite-Wall
Materials... |
|
...yet, our Mass Production
Loudspeaker Cabinets remain Cost-Competitive.
|
Curved
Loudspeaker Cabinets...
Subjective Effects |
Lows...
The curve is sharp as a razor and this brings out all of the lows in the
perfect way. Our cabinet materials can be heavy--they can be 2 times as dense as MDF for
subwoofer walls. Low frequency sound waves may be long but that also is
their downfall...via fractal effects, and thus the harmonics can be susceptible to
the exterior shape of the enclosure. Furthermore, the baffle-step effect--
omni-directional
effect of low frequencies actually creates a substantial apparent loss of
bass-power. Curved loudspeaker enclosures reduce or eliminate this
effect by allowing the Mids and
Highs to easily become more omni-directional as well thus
lowering their apparent power to the listener, and balancing the various
drivers power output. For today's bass-heavy mixes, curved enclosures are the
"ticket" because conventionally-shaped loudspeaker enclosures
unintentionally "re-mix" the sound toward the mids and highs.
Midrange...
This is where curved cabinets shine. As the sound waves approach 2x the
diameter of the loudspeaker enclosure ( resonance point ), the sound is aurally
clean as diffraction is eliminated compared to a cabinet with sharp edges. The ear is very sensitive in these
frequencies and the ear finds the music to be shimmering, clear and enveloping
compared to the same drivers in Boxes.
Highs...
The high frequency
sound waves, by default, are easiest to distort from Diffraction. Thus, all
tweeter designs receive incredible benefits from association with curved
loudspeaker enclosures. Even the lowest cost drivers sizzle.
With reasonability quality drivers, the effect becomes breathtaking and
with high-end loudspeaker drivers, the effect is
astounding. It's the rounded cabinet shape.
End Result... your loudspeaker system products just
disappear from
the acoustic soundstage even when the system uses the least expensive
drivers. Our unique enclosure manufacturing materials, even in a
box-shape, dramatically increases the look, feel, and performance of
Loudspeaker Enclosures.

CONSTRUCTION:
One could wish for
single-piece enclosure construction with no seams,
discontinuities, or other imperfection. It's possible and
perfect for loudspeaker enclosures-- and ages of high strength
engineering tell us that multiple material layers and special
chemical processes are required to achieve the ultimate product.
For example... Damascus Steel or the hundreds of
layers used for constructing the Japanese sword. Even before metal, let alone
artificial composites, ancient people made bows that could shoot an arrow almost a mile
using multiple layers of hide, horn and other materials.
Composite
Fabrication
has an illustrious role in human civilization, and has many applications where sound, vibration, and strength are
key issues. US
Enclosure
has developed the best loudspeaker enclosure materials available
and they can be mass-manufactured to your current specifications
