4. blem 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 han
