LCR-15 Full-range Speaker System

Instruction Manual

Thanks for purchasing the LCR-15 Center Channel Dialog speaker engineered by Von
Schweikert Audio, the leaders in audiophile loudspeaker technology. This 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. This universal 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 Youngs Modulus, or ratio of weight to rigidity. This permits the
woofer/midrange drivers to deliver thundering bass response in combination with
breathtaking vocal clarity and intelligibility. In addition, the liquid cooled composite
silk/polymer resin dome tweeter can handle the dynamic range and volume levels
necessary for thrilling realism without harshness or distortion. 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.

SETUP:
After unpacking the LCR-15, attach the supplied rubber squares under the unit to
eliminate vibration between the speaker and shelf or TV. Since this speaker may be
used vertically as well as horizontally, place the feet on the side you wish to use for the
bottom.

VERTICAL PLACEMENT
To use the LCR-15 as a main speaker for music, great sound can be obtained by placing
the speaker vertically. Place the cabinet so that the tweeter's VR letters face left; this is
important as the woofer unit should be on the bottom, with the midbass/midrange unit at
the top of the cabinet. The image and frequency response will be optimized when the
tweeter is at ear level.

HORIZONTAL PLACEMENT
In the case of using one or three LCR-15 speakers in a home theater setup, including
placement inside a wall unit or cabinet, the speakers may be placed in a horizontal
position. Due to the Global Axis Integration Network crossover design, the radiation
pattern is uniform in either case.

MOUNTING INSIDE EQUIPMENT CABINET:
The LCR-15 was optimized for free standing or equipment cabinet mounting. Since the
open cavity in the equipment cabinet will generate some resonance, place the speakers
close to the front edge. Alternately, if the cabinet is enclosed with a door, remove the
LCR-15's grill cover and fill the cavity surrounding the speaker with acoustic foam or
fiberglass to eliminate the cavity resonance.

TIMBRE MATCHING:
Since the LCR-15 has been designed with "flat" (accurate) frequency response, it can be
used with other brands of speakers if necessary.

LCR-15 SPECIFICATIONS

SYSTEM TYPE: Shielded three-way full range dialogue/general purpose speaker
system. One woofer is used for bass only, while the second woofer is used for midbass
and midrange frequencies. Can be mounted horizontally or vertically.

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 cabinet.

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 fail.

CROSSOVER: Global Axis Integration Network (synthesized steep-filters with phase­consistent behavior) with 300 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 finest 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.
