6. Install Grill
The grill has four neodymium magnets which are embedded in the
frame. These magnets are arranged to align with the screws that hold the
baffle in place. Simply place the grill on the baffle and align as necessary.
7. Test the speaker
Connect the speakers to your stereo system and play music through
the speakers to verify that the overall sound is full and smooth. If a
driver is not working or the sound is intermittent or distorted, please
see the troubleshooting section for possible remedies. In most cases
the cause of a problem will be traced back to improper wiring of the
crossover and not faulty drivers.
Break-In: Please allow a full two weeks of playing time at moderate
volumes before playing the system at high energy levels. This will allow
the drivers suspensions to properly break in before being subjected to
large excursions.
Care and cleaning
To protect the Dayton speaker system’s finish, use some care when
cleaning it. To remove dust from drivers, grills, or the cabinet tops, a
synthetic “feather duster” works well. For more stubborn dust on the
grills or woofers, a vacuum cleaner with gentle brush attachment may
be used. It is not recommended to use any type of cleaning apparatus
on tweeter domes; dust will not affect the sound, and the chance of
damaging the dome is high.
For cleaning streaks or fingerprints on the cabinet finishes, an
ammonia-based window cleaner is recommended. It will not affect the
finish and will leave a streak-free shine. It is important to use only very
soft, clean cloths, and to wipe gently at the surface. Intense scrubbing
or using cloths with debris on them may cause small swirl marks or
scratches. Of course, the best way to maintain the finish on the cabinet
is to prevent soiling it in the first place. Never place drinks or abrasive
objects on the top of the speaker.
Troubleshooting
Again, in most cases the cause of a problem will be traced back to the improper wiring of the crossover and not a faulty driver. Common mistakes:
using the wrong harness, improper polarity, bad or loose connections.
Problem: No output from speaker system.
Cause: Bad connection.
Solution: Check connections from the stereo to the input of the
speaker system. If OK, check the connection from the binding post
to tweeter and woofer input terminals. If this is OK, Test speaker on
another system. If sound comes out check initial stereo settings and
connections (speakers on/off). If there is no sound at all, please contact
your place of purchase immediately.
Problem: No output from woofer in individual speaker.
Cause: Bad connection or defective woofer.
Solution: Check connections from crossover board to woofer. If this
is OK, directly test the woofer by hooking it up to stereo system at
low volume setting. If sound comes out of the woofer, then go back
and check connections. If there is no sound at all, then woofer is likely
defective. Please contact your place of purchase immediately.
Problem: No output from tweeter in individual speaker.
Cause: Bad connection or defective tweeter.
Solution: Check connections from crossover board to tweeter. If OK, it
is possible to carefully test the tweeter by directly connecting it to your
stereo. Test at a very low volume for a brief period of time, at the level
of a loud whisper. If there is high-frequency sound, then go back and
check connections. If no sound at all, then tweeter is likely defective.
Please contact your place of purchase immediately.
Problem: There is sound from the speaker, but it is very quiet and
seems to be mostly treble or midrange.
Cause: Woofer and tweeter are wired backwards.
Solution: Immediately cease testing to prevent damage to the tweeter.
Check connections from crossover board to woofer and tweeter, mak-
ing sure the high pass filter denoted with a “T” on the output terminal
is connected to the tweeter and the low pass filter denoted as “W” is
connected to the woofer.
Problem: Intermittent output of entire speaker, woofer, or tweeter.
Cause: Bad connection in wires or crossover board.
Solution: If entire speaker is intermittent, then check connections
between the input terminals and the crossover board. If just woofer or
tweeter is intermittent, check the wires going to the drivers. If these are
OK, check the connections of the components within the appropriate
section of the crossover.
Problem: In stereo, speakers lack bass or image is unfocused.
Cause: Speakers are out of phase.
Solution: Check connections from amplifier to the speakers. Make
sure polarity is the same on both speakers. If correct, check the polarity
of connections going from binding posts to input on crossovers. If this
does not correct the problem, check polarity throughout the rest of the
system, looking for one driver that is wired incorrectly.
Problem: One speaker appears louder than the other.
Cause: Amplifier settings, environmental factors, psychoacoustics,
poor connection in crossover.
Solution: Check your amplifier to ensure that the balance is set even.
Next, check that one speaker isn’t closer to a wall, window, couch, or
other acoustically important object. This may affect perceived loudness
due to the addition or reduction of extra sound reflections. If this is the
case, physically switch the left and right speakers, and re-observe. If the
same location still sounds quieter, then it is the environment. If the quiet
speaker moves, then you may have a problem within the speaker. Often,
if you think one speaker is louder than the other, it will appear so. Have
someone help you do a blind test or take a break and allow time for your
brain to relax. The next day, if one still seems louder, investigate all con-
nections within the crossover.
Problem: Speakers play well, but amplifier shuts down.
Cause: Amplifier does not have enough power or cannot handle
speaker impedance.
Solution: If using 4 ohm speakers, check receiver/amplifier manual to
see if it can handle 4 ohm speakers or if it has a low impedance setting.
If not, upgrade your amplifier. If the receiver/amplifier can safely handle
the speaker load, then it may simply not have enough power.
