The McIntosh
XR 19 loudspeakers provide an unique listening experience. A pair of SR 19's
can faithfully recreate all of the stereo depth and spaciousness that is put
into a recording.
Older
technology stopped with in-line driver mounting. By assembling the drivers all
in the same vertical line, the system could be made to have equal left and
right response. This meant that stereo imaging was more accurate. A pair of
speakers would reproduce an easily located image between the speakers, but only
in the plane of the wall against which the speakers were placed. Erroneously
this was thought sufficient to reproduce stereo. Stereo is defined, however as
"having or dealing with three dimensions of spece". By careful
manipulation of response amplitude and arrival time, a degree of accuracy
beyond older technology has been achieved. By adding the dimension of depth, a
truly three dimensional sound space can be reproduced. In addition, the low and
mid frequency drivers are mounted on the same plane surface. Combined with the
elliptical tweeter array which is part of this surface, the correct time
amplitude relationship can be maintained over, a wide angle. This is not
possible with a stepped back
arrangement. The three dimensional sound space is preserved for a very large
listening area.
Definition
of individual and collective musical sounds has been improved by using multiple
drivers which reduce distortion. This arrangement greatly increases the power
handling capacity at high frequencies. The mid-range and low frequency drivers
are specially designed high power units which compliment the tweeter array. A
total of 15 drivers are built into each XR 19.
The
performance of the speakers in your listening room will be influenced to some
degree by the room size, shape, construction and furnishing. The location of
the speakers in the room advisable to voice or equalize the speakers to the
room for best performance. The McIntosh MQ 104 Environmental Equalizer is
available for this purpose. Equalization is a service that your McIntosh
franchised dealer is equipped trained, and ready to do for you. But in any
event the low distortion and wide dispersion of the XR 19's will provide
superior sound in the typical home environment.
Specifications:
Reference
Output Level : One watt input referred
to 6 ohms will produce an 86 dB sound pressure level at 1 meter
Frequency
Response : the frequency range
capability of the XR 19 is from 20 Hz to 20,000 Hz. The smoothness of response
however, nay be influenced by your listening anvironment.. Equalization can be
used to restore smooth response when necessary.
Amplifier
Damping Factor : the minimum amplifier
damping factor requirement is 10. adequate connecting wire size must be used to
maintain proper damping factor and minimize power losses. Performance of the XR
19 is not significantly improved with super high amplifier damping factors.
Power
recommendations : As little as 30 watts
can be used for smaller rooms or low listening levels. As adequate power
reserve is recommended, however, to handle unexpected peaks from program
material with wide dynamic range or when using expanders. It will also help to avoid clipping the power
amplifier which can cause distorted sound or blown amplifier which can cause
distorted sound or blown fuses. McIntosh
amplifiers equipped will Power Guard automatically prevent clipping.
Amplifiers up to 250 watts or higher can be used when the program material is
similar in spectral content to "program" noise.
