If a newly installed
loudspeaker produces a harsh sound output it is
probably caused by the speaker cone being
distorted off centre. A speaker can be checked
for this condition by gently pressing the cone
whilst holding it close to the ear. If a slight
"scraping" sound can be heard it
indicates that the distorted cone is rubbing
against the speaker barrel; a correct speaker
should be silent under these conditions.
All new speakers should be
checked as outlined before installation. This
will save unnecessary loss of time and avoid
needless owner dissatisfaction.
