LCR - 15 Full Range Dialog Speaker
Retail Price: $1,000 each
LCR-15
Full-range Dialog Speaker The LCR-15 speaker may be used as either a full range
speaker system in a conventional stereo music setup, or as a dedicated dialogue
speaker in a Home Theater application (LCR designates a speaker that can be
used in the Left, Center, and Right main positions). As a full-range speaker
for music, VSA has engineered powerful bass response combined with spectacular
stereo imaging. For use as a dialog speaker for home theater, we have created
very high vocal intelligibility into the LCR-15 by the use of two small bass/midrange
drivers instead of one larger unit, enabling a quasi three-way design.
COMPOSITE DRIVER DESIGN
Our design approach was facilitated by the use of special diaphragm materials
providing the highest Clarity Factor available. Our composite woofer cone, fabricated
from cellulose acetate pulp impregnated with mica substrate and damped with
a carbon fiber/resin polymer, has a very high Young's Modulus (ratio of weight
to rigidity). This permits the woofer/midrange drivers to deliver thundering
bass response in combination with breathtaking vocal clarity and intelligibility.
The composite design and materials were selected after listening trials to all
available cone materials over a two-year period. Each composite layer damps
the previous layer's resonances, greatly eliminating common peaks in the frequency
and phase response.
The
Ferrofluid liquid cooled composite fabric/polymer resin dome tweeter can handle
the dynamic range and volume levels necessary for thrilling realism without
harshness or distortion. After forming the dome from fabric, two layers of resin
are applied to stiffen the dome, greatly reducing the dome's resonant behavior.
As the frequency response extends down below 1 kHz, the upper midrange response
of the combined system is extremely smooth and distortion-free.
APERIODIC CABINET LOADING
In order to reproduce deep and powerful bass response without the use of reflex
porting that often adds lower midrange response anomalies, we have chosen the
pressure release system. A sealed box design eliminates the midrange resonance
generated by conventional bass reflex ported designs, but suffers from limited
excursion and dynamic range due to the air spring. To decrease the air pressure
inside the cabinet and thereby increase the dynamic range, we have installed
two "breathing tubes" at the rear of the enclosure. Note that these vents do
not contribute to the bass output, so mounting the LCR-15 into a wall unit or
cabinet will not adversely affect the deep bass.
SPECIALIZED
CROSSOVER DESIGN
To enable the LCR-15 to be used vertically or horizontally, we have designed
a GAIN (Global Axis Integration Network) crossover system that enables the system
to achieve flat frequency response in either placement. The Gain filter is a
synthesized steep-slope design formed from cascading low order filters in an
arrangement enabling a "bubble" of sound to be radiated, rather than the conventional
"flashlight beam" effect caused by excess driver overlap. There are very few
parts directly in series with the drive units, and in addition, we have used
audiophile-quality parts to increase clarity and transparency. The crossovers
are potted in resin to prevent distortion caused by vibration.
SPECS:
- SYSTEM TYPE: Shielded quasi three-way full range dialogue/general purpose speaker system. One of the two woofers is used for bass only, while the second is used for midbass and midrange. Can be placed horizontally or vertically. The optional VR-Stand may also be used.
- BASS LOADING: Aperiodic Pressure Release design using 100% stuffing density. Note that the vents are not bass reflex ports, but act as pressure release orifices. Can be placed inside a wall unit.
- BASS DRIVERS: 2pc --5.5" heavy- duty bass/mids with cast frame, cellulose acetate pulp cones impregnated with mica substrate and damped with a carbon fiber/resin polymer, Low Distortion Motor system, butyl rubber surrounds, long throw spider, high temperature voice coil and magnetic shielding. This new driver design has a very natural sound quality with inaudible coloration or distortion.
- TWEETER: 1" - composite silk/polymer resin dome with Ferrofluid liquid cooling, high temperature voice coil, Low Distortion Motor design, and magnetic shielding. This tweeter is very musical, without harshness, even at high volume levels that would cause "standard" tweeters to distort.
- CROSSOVER: Global Axis Integration Network (synthesized steep filters with phase-consistent behavior) with 220 Hz and 2.2 kHz crossover points. This crossover design has been engineered to radiate sound in a wide "bubble" instead of a "beam," so that phase and frequency response does not radically change off-axis. The audiophile-quality parts have been hand selected, including polypropylene capacitors and premium air core inductors.
- BINDING POSTS: High quality audiophile five-way binding posts with rhodium plating.
- FREQUENCY RESPONSE: 35 Hz to 25 kHz, (-6dB points, in room).
- SENSITIVITY: 87.5 dB @ one watt/one meter.
- POWER HANDLING: 8 watts min., 200 watts peak
- IMPEDANCE: 8 ohms nominal (7 ohm minimum, 19 ohms maximum). SET friendly!
- WARRANTY: Ten years parts and labor, excluding abuse such as burnt voice coils.
- WEIGHT: 28 lbs packed for shipping, 20 lbs raw.
- DIMENSIONS: 17.5" Wide x 10.25" Deep x 7.5" High (horizontally placed).

About Von Schweikert Audio
Von Schweikert Audio was founded by legendary speaker designer Mr. Albert Von Schweikert. A CALTECH trained speaker designer with a focus in Electrical Engineering he has over four decades in speaker design and is widely regarded in the industry as one of the pre-eminent speaker designers in the world. Companies such as Disney, Steinway, A&M Records, Sheffield Sound Labs, Mobile Fidelity and JVC have all sought Mr. Von Schweikert for his expertise in superior speaker design.
As a kid, he built his first speakers from kits, and modified stock drivers. He studied violin and piano, played electric guitar and worked on Time Delay Spectrometry with the famed Richard Heyser at the California Institute of Technology. While at CALTECH in the 70's, he delved into computer-based development of speaker design and psycho-acoustics, where he gained new understandings of sound radiation and how this was perceived by the listening audience.
After he left CALTECH University he worked with numerous different audio companies and was responsible for quite a few, and sometimes very spectacular speaker designs. He was in charge of more than one hundred projects, and while many of them don't display his name, most were very well known companies. As one of the world’s most experienced speaker designers he's worked with Bose, JBL, ESS / Heil, Eggleston, Apogee, Cerwin Vega, Counterpoint, Jensen, NHT and many others.
In the mid 90’s Von Schweikert Research moved the whole operation from the West Coast to Watertown, New York. The business enjoyed strong growth there until in 1999 a large flood destroyed most of the company. Financially strong investors urged the company to move back to California where "Von Schweikert Audio“ – abbreviated as VSA – was founded.
VSA has speakers in current production that range from $1,000 to $150,000 and the current product line-up includes nine models: from the compact VR-1 up to the monstrous VR-11. Center and surround-speakers and also several subwoofers top off the line for home cinema lovers. With an expansive global dealer base, the company has been enjoying strong and continuous growth while still pioneering innovative new designs and technologies for accurate and realistic sound reproduction.
With over 30 industry awards and a veritable "Who's Who" of famous clients, Von Schweikert Audio is THE speaker of choice for those who demand the world's very best.
