PRESS RELEASE - VON SCHWEIKERT AUDIO NOW IN BUSINESS
NEW COMPANY
December 1, 1999- Dr. Edward Gonzaga of the Gonzaga Investment Group, is proud to announce
the formation of a new audiophile speaker company, Von Schweikert Audio. Headed by noted
designer Albert Von Schweikert, the new company has announced the release of two all-new
speaker systems, the VR-5 and VR-7. In addition, service and updates will be offered for
all former VSR speaker systems. Please contact the company at albertvonn@aol.com for
further information regarding service or updates.
DEBUT: CES, LAS VEGAS
Von Schweikert Audio will be debuting the new VR-5 and VR-7 systems in the Presidential
Suite #1903 at T.H.E. SHOW being held at the St. Tropez Hotel in Las Vegas January 6-9,
concurrent with CES next door at the Alexis Park Hotel. Room partners are Bel Canto
electronics and Analysis Plus cable company.
NEW DESIGN GOALS
Albert Von Schweikert's new design goals are to increase transparency and lower distortion
in the quest for sonic realism. Towards that end, all new drivers were specified and/or
engineered, including soft-dome tweeters and aluminum woofers for greater accuracy and
musicality. A new cosmetic styling is evident as well, with premium woods and contemporary
furniture in mind. Stunning great looks using elegant simplicity is the key to user appeal
and the new Italian cosmetics will complement any décor. The sound quality of the new
VR-5 and VR-7 is impressively musical and natural, surpassing the earlier VR speaker
designs by a wide margin.
NEW MODELS:
VR-5 ($5,950/pr to $7,500/pr depending on finish)
The VR-5 is a four way Reference Grade speaker system using the world's finest drivers,
crossover parts, and internal wiring. The VR-5 can be regarded as a bargain as it will
compete sonically with any speaker several times its price and is one of the most
beautiful speakers available.
CABINET
The elegant 42" wood tower features 1.5" thick walls and heavy cross bracing,
with an internal damping layer consisting of 1" thick rubber and felt lining the
walls. This level of sound deadening is unprecedented at this price point and permits the
VR-5 to have breath-taking transparency with no coloration. Standard finish is light
maple, with other finishes available.
WOOFER SYSTEM
Twin 180mm aluminum coned SuperDuty woofers made in Europe reproduce the bottom octaves
with authority and delicate clarity, using a modified transmission-line tuning to achieve
response flat to 28Hz (-6dB at 20Hz). Bass definition and punch are at state-of-the-art
levels due to the long-throw aluminum woofers. These premium-grade drivers use a special
low distortion motor, allowing very clean midbass along with thundering deep bass. To
eliminate the noise caused by a conventional dust cap, a specially designed phase plug is
used in the center of the cone. The modified transmission line tuning utilizes heavy
stuffing to eliminate cavity resonance, the source of midbass boom in competing systems.
To reproduce the bottom octave with authority, the 3" vent is foam-lined and has a
6" flared mouth to eliminate wind noise and coloration. When listening to the VR-5,
you'll be able to discern the individual mallet strikes in a drum roll or feel the deep
impact of a Fender bass!
MIDRANGE SYSTEM
Midrange frequencies are very accurately reproduced by a French state-of-the-art 5.5"
driver using a composite cone made from carbon fiber, Kevlar, and cellulose acetate pulp.
This new cone material, along with the edge-wound ribbon voice coil and special
suspension, allows transparency equal or superior to any driver, whether electrostatic or
ribbon. This extremely light cone has very high internal damping due to the composite cone
structure and can trace very delicate waveforms with stunning precision. Coloration and
distortion of mid frequencies are virtually unmeasurable, allowing the VR-5 to reproduce
voices, piano, and other difficult sources
similar to a live event. This superb driver is backloaded by an infinite transmission line
using progressive Gradient Density absorption. This proprietary technique consists of
4" thick felt and foam rubber wedges edge-loaded to eliminate coloration in the vital
mid frequency range.
TREBLE SYSTEM
The Excel soft dome tweeter is one of the world's finest tweeters, using the transmission
line principle to eliminate back pressure. The Sonotex fabric dome is internally coated
with a proprietary damping material to eliminate flexing and distortion that compromises
lesser fabric domes. Using an ultra-linear long-throw motor system and Ferrofluid cooling,
distortion is lowered beyond that of conventional dome tweeters, resulting in
electrostatic-type clarity. Moreover, dispersion and smoothness are at state-of-the-art
levels, resulting in one of the most transparent yet sweet treble ranges available, and
far surpassing metal domes.
AMBIENCE SYSTEM
The rear-firing ambience driver is a 1" cloth-dome unit made in Norway and features
very low distortion due to a Sonotex coated dome, Ferrofluid cooling, and a transmission
line vented rear chamber to eliminate distortion and back pressure. There is an adjustable
volume control for this rear driver and it's ambience circuit, enabling just the right
amount of "air" and "space" to be generated for ultimate soundstage
depth. The Dimension control can compensate for any acoustic condition and/or room
placement and can be switched off if desired.
CROSSOVER DESIGN
The crossover design is based on acoustic fourth order slopes combined with first order
slopes, using a minimum of parts in the signal path. In the quest for greater transparency
combined with ultimate smoothness, Hovland capacitors are used in the treble range, along
with Eagle metal film resistors and Solen air core inductors. All woofer components can
handle up to 1500 watts before saturation or distortion, allowing tremendous dynamic range
without boom or compression. The woofer circuit is physically separated from the
mid/treble crossovers for elimination of crosstalk and distortion and permits bi-wiring if
desired. The midrange crossover circuit uses a minimum of extremely high-grade components
to reduce parasitic absorption of the signal, enabling very realist vocal reproduction.
Internal wiring is custom designed for the VR-5's drivers, with 9AWG woofer wiring
supplied by Analysis Plus and midrange/treble wiring designed and supplied by Robert Lee
Audio.

VR-7 ($15,000/pr to $19,000/pr depending on finish)
This is a new replacement for the VR-6 that was awarded "Product Of The Year" by
Audioland magazine, Hong Kong, in December 1998. The VR-6 also won "Best Sound Of The
Show, 2nd Place" at the Stereophile Show in San Francisco, 1997, and has appeared on
the front cover of leading magazines in Germany and Holland. As many magazine reviewers,
leading audiophiles, and famous musicians use the VR-6 as their reference speaker, calling
it "one of the best speakers in the world," the VR-7 has to be something
special. And that it is: using the world's finest engineering and component parts, the
VR-7 is a sonic powerhouse and although expensive, the 7's are a bargain due to their
incredible realism, stunning cosmetics, and heroic build quality.
CABINET
The Italian-designed cabinet is a graceful 52" tower with a swept-back top and
swept-back side cheeks that are carved from solid hardwoods. The cabinets are damped by
multi-composition walls using constrained layer laminations, with a 2.5" thick front
baffle and 1.5" thick side walls. Internal damping/sound-proofing includes a 1"
thick internal wall coating composed of felt and rubber layers. This exclusive combination
of engineering and materials allows the VR-7 to be the most neutral sounding speaker
available, without resonance or coloration. The VR-7 can easily take it's place in the
most elegant of rooms, and sonically, it simply disappears, generating a holographic image
that has to be heard to be believed.
WOOFER SYSTEM
In order to reproduce the high impact and punchy bass of today's recordings, combined with
ultra-detailed midbass clarity, the VR-7 utilizes twin magnesium metal-coned 200mm
Superduty woofers. The magnesium cone is the lightest yet stiffest cone available,
enabling incredible volume levels to be attained at very low frequencies without
distortion or coloration. In addition, the metal cones allow heat to be radiated from the
voice coil, lowering the distortion and compression found in other cone materials.
Furthermore, the motor system uses a patented method of eliminating "fringe"
distortion caused by the movement of the voice coil in the fixed magnetic field. These
design features and resulting sonic excellence is unsurpassed by any other woofer we know
of, at any price.
The transmission-line tuning system uses heavy stuffing to eliminate cavity resonance and
midbass boom, while the bottom octave is reproduced with tremendous authority by the
rear-firing 4" vent with 7" flare to reduce wind noise distortion. This
combination of design elements enables the VR-7 to have the finest sounding bass
reproduction of any speaker we know of.
MIDRANGE SYSTEM
In order to move the large volume of air necessary for maximum dynamic range, the driver
selected is a cast frame 6.5" unit hand-made in France. To reproduce the vital
midrange with high detail and low coloration, the driver utilizes a very stiff but light
cone made from a composite of carbon fiber, Kevlar, and cellulose acetate pulp. This
aerogel cone has extremely high internal damping, enabling a very high level of
transparency to be achieved surpassing that of any other driver we have ever tested. To
eliminate coloration, the backwave is absorbed by an infinite transmission line using
Gradient Density absorption, created by 10" thick edge-on layers of foam rubber and
felt wedges.
TREBLE SYSTEM
To reproduce the high level of detail required to match the aerogel midrange driver and
magnesium coned woofers, a very highly engineered Scanspeak dome tweeter was selected.
This silk dome with proprietary coating enables very high clarity without distortion or
harshness found in metal dome tweeters. To further enable high volume levels without
distortion, Ferrofluid is used along with a special underhung motor system which
eliminates "fringe" distortion caused by the voice coil leaving the magnetic gap
at high excursion levels. To eliminate the coloration found in conventional dome tweeters,
this Scanspeak unit was designed with the transmission line principle, using a rear vented
chamber to absorb the backwave. These engineering features allows the VR-7 to have the
best of both worlds: very high detail retrieval combined with utterly sweet musicality.
AMBIENCE RETRIEVAL SYSTEM
In order to generate a deep soundstage combined with holographic imaging for more than one
person, a rear firing ambience driver is utilized. This driver is a 1" silk dome
tweeter using a special ambience recovery circuit and Dimension control. This allows the
ambience effects to be controlled for every acoustic situation or can be switched off if
desired.
CROSSOVER DESIGN
To enable a linear phase reproduction combined with ruler flat frequency response, both
first order and fourth order acoustic slopes are utilized. This combination of crossover
slopes enables the highest level of transparency by eliminating many crossover elements,
but also protects the drivers from distortion caused by undesirable out-of-band
frequencies. Only the finest components were selected, including Hovland capacitors, Solen
air-core inductors, and Eagle metal film resistors. All wiring is custom designed and is
furnished by Analysis Plus for the twin woofers and Robert Lee Audio for the midrange and
treble. The woofer circuit board is physically separated from the midrange and treble
boards, enabling bi-wiring. All crossover parts can withstand 1500 watts before distortion
or saturation, eliminating compression of dynamic range. In addition, the circuit boards
use 9AWG copper buss-bars (instead of thin plated traces) and are hand wired point-to-
point for added transparency and freedom from distortion.
