BACKGROUND AND HISTORY
4" diameter ( .02 cubic foot )
36" diameter ( 12.9 cubic feet )
capability to manufacture to
240" diameter *20 foot* ( 4190 cubic feet )
|• Boeing avionics radar dome design.|
|• Circus Circus Hotel and Casino, 80 custom-designed spherical loudspeaker enclosures for large venue in Reno, Nevada.|
|• Cirque du Soleil, design for PA application.|
Columbia University / Princeton University,
innovative multi-driver 360 degree field design in a
14-inch spherical 720 watt monitor/PA-- called
" Acoustahedrons "
|• Ericsson (of Sweden) loudspeaker enclosure for anechoic sound chamber calibration.|
|• US Government contracted US Enclosure for products for Military efforts against Terrorist Attacks.|
Designer and Manufacturer of the Largest spherical
loudspeaker enclosures. We manufactured 36"
diameter carbon-fiber braced spherical loudspeaker
our competitors largest is just 12" and made of aluminum... ( our largest product is 24 times the volume, 3 times larger in diameter ); and a capability to go to
96" diameter for Sound Reinforcement applications.
Largest egg-shaped loudspeaker enclosures ever sold.
These enclosures are the only ones of this shape that
are engineered with no internal diffraction as a
element for better sound quality. Other companies have used the shape for tweeters and only applied the exterior shape for sound quality improvements.
|• Only Wing-Shaped Parabolic loudspeaker enclosures ever built, which are ALSO the only floor standing (Curved) parabolic shaped loudspeakers ever built ( 30" tall ).|
|• Levitated Composite Core loudspeaker stuffing system devised by US Enclosure Company.|
|• Super-Stuffing 10 times as sound absorbent as any loudspeaker stuffing material currently on the market.|
|• Spherical D'Appolito configuration (MTM) utilizing ribbon tweeters.|
ONLY COMPANY that engineered & developed to
market a FULL-LINE of Curved Cabinet Loudspeaker
Enclosures; Subwoofers to 25hz -3 db; Complete THX
Home-Theater systems; A Full/Wide Range line of speakers; all using our enclosure materials and designs. Example, we began manufacturing bi-polar (di-pole) Rear-
Channel spherical speakers in 1997 to accommodate the unique demands of THX home theater.

|One of our
strong points is our utilization of acoustic
principals in loudspeaker enclosure materials and design
principals. Our best known design products are
loudspeaker enclosures with a shape which reduces
acoustic diffraction effects compared to all common box
shaped loudspeaker enclosures We have taken this
design/shape concept to a new level of
manufacturability... walls equal to or better
acoustically than any wood based
We have the unique combination of customer experience and service, curved cabinet manufacturing and design expertise, and curved-cabinet manufacturing experience Our acoustically improved and visually appealing cabinets fit in any environment... home, professional media production facility, or concert hall.
OEM Loudspeaker Manufacturers cabinets can be refreshed as a design improvement for existing lines or for a completely new product line. The designs are then eye-pleasing and consumer acceptable. They also reduce cone bleed-through and exterior diffraction which improves your products sound.
Finally, we specialize in loudspeaker cabinets, yet, our technology lends itself to a wide variety of other applications involving wave energy-- from optical integrator spheres to industrial containment vessels.

tests confirm that all spherical-shaped loudspeaker
enclosures have unique resonance's inside the curved walls. Engineering-work begins for special
dampening of spherical sound waves which lead him away
from standard loudspeaker
stuffing to a focus on (A) finding the truly-proper Enclosure Wall Materials specifically designed to absorb the energy inside
a loudspeaker enclosure for (B) any loudspeaker cabinet shape to be (C) mass-manufactured.
the loudspeaker enclosure wall material developed from
this research and, in August 1992, fully perfected
for loudspeaker cabinet mass production.
|First multi-modulus test-enclosures produced for acoustic test purposes.|
Enclosure Company originates, shortened in 1995 to US Enclosure
Metaverso incorporates Levitated Composite Core technology inside spherical loudspeaker enclosures to defeat the standing
waves inside curved loudspeaker enclosures.
|| Brian O'Neill
begins to use the Pre-WWW Internet to market a product
he manufactured and marketed since 1989.
Previous to the Internet marketing experience, O’Neill originally used 10 nationally distributed specialty periodicals to market
his product called a "Sock Monkey" doll for babies. The motion picture Cabin Boy featured his product in one scene.
O'Neill's “Sock Monkey” was also featured on ABC-TV's Home Show in 1992. Company Name: The Marketing Tide.
Metaverso tests multi-modulus loudspeaker enclosures for mass-manufactured designs. The first multi-modulus loudspeaker
enclosure with a multi-driver configuration produced with each driver having it's own curved enclosure within the main curved
enclosure body. This cabinet also used Levitated Composite Core stuffing technology and techniques.
Metaverso and O’Neill meet. O’Neill applies his experience with advertising, marketing & sales to Metaverso's loudspeaker
cabinet innovations and US Enclosure Company organizes.
First multi-driver multi-modulus spherical curved enclosure designed, manufactured and sold to third-parties.
