6. CAUTION--CAUTION--CAUTION
A) The terminal plate states a maximum fuse value of 4 amps Type 3AG
(“normal” or fast blow”) We recommend that 4 amp fuses continue to be
used. The bass section does not require fusing protection. This fuse
value should never be increased or bypassed. Do not use slow-blow
fuses. If these precautions are taken, our destruct tests show that it is
impossible to burn out these drivers. BURNED OUT TWEETERS ARE
NOT COVERED UNDER THE WARRANTY.
B) For owners of cats, we recommend cat repellent around the base of the
speakers.
7. SPEAKER PLACEMENT
Proper speaker placement and room acoustics can have more effect on a music system
than upgrading one of the components in the system. Unfortunately, there is
no definitive guideline which will cover all possible listening rooms. Some
experimentation is required for locating the optimum position. The following are a few
general guidelines:
A) BASS RESPONSE --Play a record (or test signal) with repetitive bass. Try the
speakers in several possible locations in the room. Begin moving the speakers
forward or backward in increments of 6 to 12 inches. One position in the room
should be noticeably better than others. Also experiment with your chair location.
Positions close to a wall will often result in increased bass (often too much). See
Figure 2.
B) STEREO WIDTH AND IMAGING --Once you have located the best position for
the speakers and your chair for bass performance, separate the speakers by
50% of the distance from your chair to the speakers. (For example, if your chair
is 10 feet from the speakers, move the speakers 5 feet apart.) Now, move the
speakers apart in increments of 3 or 4 inches at a time, listening carefully at each
position. At some point you will start to hear two separate speakers instead of a
“stage effect” (or continuous image). When this occurs, your speakers are too far
apart: begin moving the speakers back in small increments until you notice a
point at which you achieve one cohesive “sound stage.” For best results listen to
speakers on axis with the listening position as shown in Figure 1 and 2.
