Since the major portion of the energy reproduced by the low frequency
loudspeaker lies below 500 Hz, this specification has been developed by using
a test signal warbled from 100-500 Hz, rather than the conventional 1 kHz
sine wave test signal on which the EIA sensitivity rating is based.
Due to the Paragon’s special acoustic characteristics, per
formance is virtually the same regardless of room placement.
However, if the listening room is unusually "live” and con
sists primarily of hard, reflective surfaces such as large,
exposed windows, paneled walls and hard wood floors and
ceilings, sound quality may be adversely affected through
the loss of clarity. To improve the acoustic characteristics

of such rooms, it is wise to place drapes, tapestries, book
shelves or similar items on the wall behind the listeners.
The Paragon is shipped in three parts; the left- and right-
hand halves of the enclosure and the convex refractor panel
The two legs located at the front of the enclosure are
adjusted and locked at the factory. The four legs located at
the rear of the enclosure should be adjusted by the user at
the position occupied by the system in the room.
After establishing where the system will be permanently
located, the two main enclosure sections can be leveled by
adjusting the two outer legs to approximately the correct
height; then, push each enclosure section together so that
the dowel pins on one side fit into the corresponding holes
in the other. A minor readjustment of the two outer legs is
usually required to obtain a perfect fit. When the enclosure
sections are properly mated, the legs should be secured in
position by the locknuts provided.
The two enclosure sections are semi-permanently locked
together by six wedge brackets: three in the front and three
in the rear.
Fit the wedge clips over each bracket and drive them into
place by tapping downward with a small hammer. Insert a
single wood screw through the hole in each clip to hold it
in position.
