LCR (Left/Center/Right) Design: The McIntosh LCR80
loudspeaker is designed for use in a stereo or home theater system; and can be
used as Front speaker, Center speaker, Surround speaker, or Surround back
Flexible Mounting Options: With its flexible design, the LCR speaker
can be tabletop or wall-mounted, and can be positioned either horizontally or
vertically. Mounting hardware is supplied for each mounting option. The patented Rotatable Dispersion Pattern Baffle Board
assures the same wide dispersion and excellent sonic
imaging whether the LCR80 is positioned vertically or horizontally.
- Rear Stabilizer Feet: The two Rear Stabilizer Feet allow you to
place the LCR80 speaker horizontally on a flat-surface, like a piece of AV
furniture, stand, or shelf. You can reposition the rear stabilizer feet to
vary the angle of the speaker from - 11°,
0°, or +11°.
This allows the sound to be directed upwards or downwards
toward the listening area.
- Wall-Mount Brackets: The supplied wall-mount brackets allow for
different mounting positions of the LCR80 loudspeaker relative to the wall,
both vertical and horizontal. Two positions are flush mount, with the
Loudspeaker close to and parallel with the wall. The other position is an
angle mount, which places the loudspeaker further away from the wall and
allows for rotation of +/-30°, so you can
better direct the sound toward the listening area.
3 Upper Frequency Drivers: McIntosh's LCR80 loudspeaker
utilizes 3 upper-frequency drivers. There is one 0.75" titanium dome tweeter and
two 2" midrange inverted titanium dome drivers. The tweeter and midrange drivers
are precisely aligned on the precision machined mounting plate of 0.625" inch
thick aluminum. Their unique layout and crossover design combine high power
handling with precise sound-staging. Locating the tweeter between the two
midrange drivers generates a symmetrical polar response for superior imaging.
Since the audio power is distributed among all the drivers, each driver does not
have to work as hard, resulting in greater power handling capability, dramatic
reduction in distortion, and greater dynamic range.
Neodymium-Iron-Born Alloy Magnets: The 0.75" tweeter and two
2" midrange drivers all employ a neodymium-iron-born alloy magnet.
Neodymium-iron-boron alloy has the highest flux density per unit of volume. This
allows for a smaller physical size driver and thus closer driver-to-driver
placement for improved dispersion.
Patented LD/HP Woofers: The low frequency section of the
LCR80 loudspeaker consists of two newly designed McIntosh patented LD/HP 6"
woofers. The McIntosh patented LD/HP woofer offers increased power handling and
produces incredible deep bass with low distortion. The woofer features a
polypropylene cone with a rubber surround and has a four layer copper voice
coil, so it can perform as a near perfect air piston. The rear vent through the
magnetic assembly offers improved heat dissipation. The die-cast basket has an
open air area under the voice coil/spider assembly to prevent displacement
noise. All together these advances in woofer design construction and materials
produce the very important first several octaves of music, with a high degree of
accuracy and superb transient response.
Precision Crossover Network: The crossover network used in
the LCR80 loudspeaker is designed to ensure an even frequency response over the
entire audible range. The 2nd order designed network utilizes capacitors and
inductors with high-current capacity. The Capacitors used are the low loss (ESR)
types. The low-loss (DCR) inductor used in each section of the crossover network
has been chosen for high linearity, even at high power levels. This prevents
distortion of the music at any frequency. The crossover network also utilizes
self resetting high current PTC fuses to provide an extra measure of protection.
Real Wood Veneer, Rigid Enclosure: The LCR80 loudspeaker's
enclosure is constructed with non-parallel internal sides to reduce internal
standing waves. It has multiple front-to-back and side-to-side internal braces
to form a dampened rigid loudspeaker enclosure. The LCR80 is available in
various real wood veneers with a high gloss polyester finish. Fine gloss wood
finishes are offered in Black or Red Walnut. These high-gloss finishes and fine
cabinetry will be a welcome addition to even the most elegant homes.
Magnetic Grille: The custom designed molded loudspeaker
front grille is covered with a neutral black cloth and is secured to the speaker
cabinet using neodymium magnets. The magnetically attached grill exhibits nearly
perfect acoustic transparency. The design of the LCR80 loudspeaker took into
account the acoustic characteristics of the front-panel grille and it should be
attached to the loudspeaker for the best sonic performance.
Gold-Plated, Binding-Post Terminals: The LCR80 loudspeaker
features McIntosh Patented gold-plated, binding-post terminals to receive high
current power & audio signal from your power amplifier, integrated amplifier, or
receiver. These binding post terminals will accept large diameter wire (up to
10AWG), banana plugs (single only), and spade lugs.
Placement: Loudspeaker placement in a room can greatly
affect performance. Placement near a wall, corner, floor, ceiling or any
intersecting surfaces will reinforce or diminish some bass frequencies. Try
various locations by listening to music containing continuous bass and finding a
location where there is an over all musical balance in the sound and the bass
content does not dominate. There should be an unobstructed area in front of the
Loudspeaker of at least 30 either side from the center axis for the best
performance. The distance between the loudspeakers and the listener to the
loudspeakers should form an acute isosceles triangle. If the speakers are too
far apart relative to the listener, some imaging can be lost. The LCR speaker should also be placed as close to ear level as possible.
Loudspeaker Protection: The LCR80's built-in speaker
protection incorporates three automatic resetting solid-state devices in the
crossover network. One protects the tweeters, one for the midrange drivers, and
one for the woofers.
