Loudspeaker

“a versatile performer with

a

bessel function tweeter array...

a

speaker that excels in any capacity”

Combining a 5-tweeter Bessel function array for smooth and even
dispersion with four powerful 8-inch woofers and a 6.5-inch midrange,
the XR27 loudspeaker delivers superb audio performance, high power
handling, low-profile styling and -of course- astounding flexibility.

Designed to exceed the exacting demands of music reproduction in pure
audio systems, the XR27 also delivers astonishing performance in
theater systems. Extended low frequency response and 1200 Watt
power handling capacity enable the XR27 to easily handle the crashes,
explosions and other sound effects that add excitement to the home
theater experience and to deliver exceptional dialog clarity so critical to
the enjoyment of movie soundtracks.

The XR27 performs equally well in horizontal or vertical positions and the
shallow depth of the extruded aluminum housing allows placement
options that include on-wall or in-wall mounting as well as self­supporting stands.

HOME THEATER

AND MORE

Many of today’s speakers are

designed only for home theater. Not

so with the XR27 Loudspeaker

System, designed also for the

flawless reproduction of music.

While the explosions, screams and

crashes so common in today's movies

require wide dynamic range and high

sound pressure levels, these sounds

are so loaded with noise that even a

speaker with moderate distortion can

reproduce them with little

audible error.

Music, however, while sometimes

dynamic is always harmonious and

accurate reproduction of music

demands the lowest levels of

both harmonic and

intermodulation distortion.

Each driver and crossover component

in the XR27 has been carefully

designed for low distortion to ensure

that the system could reproduce

everything accurately, from bombastic

sound effects to the delicate nuances

and detail in music.

A DECORATORS DREAM

EXTRUDED ALUMINUM ENCLOSURE

An extruded aluminum enclosure
with solid aluminum end plates
creates an extremely strong and
durable enclosure that will not
distort sound with vibration or
flutter.

MULTIPLE APPLICATIONS

XR27s can be used as left and right
channels in stereo systems, or
employed in multiples as left,
center, right and surround speakers
in theater systems.

FIVE TWEETER BESSEL FUNCTION ARRAY

Tweeter amplitudes and phase
relationships are adjusted to create
a high frequency point source. The
resulting smooth and even acoustic
polar response allows listeners to
move off axis without suffering a
change in high frequency output.

GOLD PLATED BINDING POSTS

Dual sets of input binding posts are
gold-plated for superior corrosion
resistance.

PATENTED LD/HP TECHNOLOGY

The McIntosh drivers, woofers and
midranges feature the patented
LD/HP motor structure. This design
uses aluminum shorting rings at
both ends of the pole piece to
extend and linearize the magnetic
field around the voice coil.
Distortion is reduced by 10dB or
more.

SHIELDED MAGNETIC FIELD

The XR27 may be used in home
theater installations near a television
receiver or monitor. Shielding
around the drivers ensures that the
speaker magnets will not interfere
with the quality of the picture.

ADJUSTABLE STABILIZER

The XR27 stabilizer stand attaches
to the back of the cabinet, allowing
the speaker to be angled up or
down.

MOUNTING OPTIONS

Brackets attach directly to the wall
in a vertical or horizontal position.
In-wall kit and self supporting
stands also optional.

HIGH POWER HANDLING

Drivers and crossover components
are chosen for high-power
amplifiers up to 1200 watts for the
complete system.

HIGH EFFICIENCY DRIVERS

Even the smallest McIntosh power
amplifiers provide sound pressure
levels in excess of 100dB at 1
meter.

THREE-WAY DESIGN

The design consists of five 1"
tweeters, one 6.5" midrange and
four 8" woofers.

No matter how great the sound, a

great speaker should not conflict with

the style or decor of the room. The

XR27 can be mounted on the wall,

either vertically or horizontally and can

even be installed in the wall where

they will seemingly disappear.
