4. If possible, locate the speaker 1V& to 3 feet from the side wall
or openings into adjacent rooms (Diagram 2. page 6).
5. Allow at least 1 feet of space on the side of the speaker where
the Direct Energy Control and tweeter are located. This will
provide for the best dispersion of high frequencies into the room.
6. The most accurate bass will be obtained with the back of the
speaker against a wall or moved out up to 2 feet. Further spacing
from the wall will result in some reduction In middle bass
response. This effect happens with all loudspeakers.
VERTICAL PLACEMENT Should you desire to position the speak
ers vertically, the above guidelines should be followed, with the
exception that No. 5 will apply to the areas above each speaker
rather than to areas on the side. Be sure to place the speakers
so that the tweeter is on top. As with ail small speakers, placement
directly on the floor will accentuate bass and restrict distribution
of high frequencies.
Note that for vertical placement, the nameplate can be rotated
and moved. Carefully remove the foam piece containing the name
plate. Squeeze the small tab retaining the nameplate. Reposition
the nameplate and replace the tab.
QUADRIPHONIC OPERATION All of the above considerations
are valid when operating the BOSE Model 301 speaker system in
quadriphonie or four-channel sound reproduction. Because of the
flexibility the BOSE Model 301 speaker system provides in room
placement, the operation of the speaker system in four-channel
modes is optimum for more listening environments than that of
conventional loudspeakers. This is due to the fact that the amount
of direct-energy reaching the listening area can be specifically
adjusted at each speaker.
Diagram 4 indicates the placement position of the BOSE Model 301
in quadriphonie and stereo operation. If your listening environment
does not allow the possibility of placing speakers behind you, the
Model 301 speakers can be placed as shown along the side walls
of the listening area with the Direct Energy Control set for mini
mum direct energy (see section on adjustment of the Direct Energy
Control).
