11 Upper Frequency Drivers: McIntosh's XR100 floorstanding speaker
utilizes 11 upper-frequency drivers. There is one 0.75" titanium
dome tweeter and ten 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 multiple 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.
Multiple Midrange Drivers: Eight of the ten midrange drivers reproduce
the lower two octaves of midrange, while the remaining two midrange drivers
reproduce the upper two octaves of midrange frequencies and are located directly
adjacent to the tweeter. This type of design maintains wide dispersion with a stable sound image
throughout the upper midrange frequencies. There are several benefits when using
multiple Midrange drivers.
- First, there is a substantial increase in power handling capacity far
greater than a single larger diameter midrange driver.
- Second, due to mutual acoustic coupling there is an increase in output
volume while at the same time a reduction in audible distortion.
Neodymium-Iron-Born Alloy Magnets: The 0.75" tweeter and ten 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.
4 Patented LD/HP Woofers: The low frequency section of the XR100
floorstanding loudspeaker consists of four newly designed McIntosh patented
LD/HP 6" woofers. These four McIntosh patented LD/HP woofers offer increased power handling and produce incredible deep bass with low distortion. Each 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 XR100 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.
Bass Port: The McIntosh XR100 floorstanding speaker
utilizes a vertical port with a rear opening to increase bass output, reduce
distortion and improve the overall efficiency of the loudspeaker.
Real Wood Veneer, Rigid Enclosure: The XR100
loudspeaker 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 XR100 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
XR100 loudspeaker took into account the acoustic characteristics of the
front-panel grille and it should be attached to the loudspeaker for the best
Dual Gold-Plated Binding Posts: The McIntosh XR100 is equipped with
dual sets of McIntosh Patented gold-plated, binding-post terminals so you can
bi-wire or bi-amp the speaker. These binding post terminals will accept large
diameter wire (up to 10AWG), banana plugs (single only), and spade lugs.
- Bi-Wiring: Bi-wiring can provide noticeable
improvements in the overall transparency of your loudspeakers. Run separate
speaker wires to the low & high frequency drivers from a single amplifier
(the upper set of binding posts are for the high frequency drivers; the
lower set of binding posts are for the low frequency drivers).
- Bi-Amping: Bi-amping allows you to use separate
amplifiers for the high & low frequency sections of your loudspeaker for
greater dynamic range & lower distortion. We recommend that your separate
amplifiers have identical gain to preserve the speaker's voicing balance.
Mounting Feet: The XR100 floorstanding speaker's four mounting must be
installed for optimum sound and proper stability. The mounting feet attached to
the bottom of the speaker cabinet using the included hardware. You also have
your choice of four glides or tiptoes, which screw into the bottom of the
mounting feet. The glides are ideal for protecting your tile or hardwood floors,
while the tiptoes provide better stability for carpeted floors.
Applications: The McIntosh XR100 floorstanding loudspeaker is sleek and contemporary
in appearance while producing full-range audio sound. The XR100
floorstanding loudspeaker is designed for both music and home theater systems,
and can fill large rooms with full-bodied sound. Amplifiers from 75 to 600 watts are appropriate power for the XR100 speaker.
Placement: Loudspeaker placement in a room can greatly
affect performance. Placement near a wall, corner, 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.
Front-Panel Logo Illumination: The even Illumination of the
front-panel "McIntosh logo is accomplished by the combination of custom designed
light diffusers and extra long-life light emitting diodes (LEDs).
Power Control: The Power Control Input (3.5mm) supplies power to
illuminate the XR100's McIntosh Logo, while the Power Control Output (3.5mm)
supplies power for remote turn-on of additional Components.
Loudspeaker Protection: The XR100's built-in speaker protection
incorporates four automatic resetting solid-state devices in the crossover
network. One protects the tweeters, one each for the low and upper midrange
drivers and one for the woofers.
