It had long been the practice of stereo buffs to connect their
television to the stereo system. The advantage was the use
of the larger speakers and more powerful amplifier of the
stereo system. Even though the sound was greatly improved, it
was still mono and limited by the broadcast signal.
In the late 1970’s and early ‘80’s two new home movie
formats became widely available to the public: VCR and
laser disc.
By 1985, both formats had developed into very high quality
audio/video sources. In fact, the sonic performance of some
video formats exceeded audio-only formats. Now, with
theater quality sound available at home, the only element
missing was the "surround sound" presentation found in
movie houses.
Fortunately, "Dolby” and ”DTS" encoded movies (which
include almost all movies) have the same surround sound
information encoded on home releases as the theater films.
All that is required to retrieve this information is a decoder
and additional speakers and amps to reproduce it.
Home theater is a complex purchase and we recommend
that you consult your local MartinLogan dealer as they are
well versed in this subject.
Each piece of a surround system can be purchased
separately. Take your time and buy quality. No one has
ever complained that the movie was too real. The following
list and descriptions will only give you a brief outline of the
responsibilities and demands placed on each speaker.
Front Left and Front Right
If these speakers will also be the same two used for your
stereo playback then they should be of very high quality
and able to play loud (over 102 dB) and reproduce bass
below 80 Hz.
Center Channel.
This is the most important speaker in a video system, as
almost all of the dialogue and a large portion of the front
speaker information is reproduced by the center channel.
It is important that the center speaker be designed by
the same manufacturer as the front speakers, and that it is
recommended for use as a center speaker. This is not the
place to cut corners.
Surround Speakers.
We recommend that the surround speakers play down
to 80 Hz or below. The surround speakers contain the
information that makes it appear that planes are flying over
your head. Some may suggest that this is the place to save
money and purchase a small inexpensive speaker. If you
choose to do so, be prepared to upgrade in the future as
discrete six channel digital encoding becomes available
and the demands on the surround speakers increase.
Subwoofer.
With any good surround system you will need a high quality
subwoofer (the .1, in a 5.1 channel surround system). Most movie
soundtracks contain large amounts of bass information as
part of the special effects. Good subwoofers will provide a
foundation for the rest of the system.
