WE WANT YOU LISTENING FOR A LIFETIME
Used wisely, your new sound equipment will provide a lifetime of enjoyment. Since hearing damage from loud noise is often
undetectable until it is too late, THIEL and the Electronics Industries Association’s Consumer Electronics Group recommend
you avoid prolonged exposure to excessive noise. Depending on room size and amplifier power, some home audio systems
can reach sound pressure levels in excess of 95 decibels with peaks of over a 105 decibels. For your protection, the list below
identifies sound levels for various noises.

GRILLE
The CS2.3 grille is designed to not produce diffraction so there is no sonic
reason to remove it. If you do need to remove the grille, pull the bottom of
the grille frame away from the speaker an inch or so and then lift the grille
upward to remove it. When replacing the grille, first push the top down
onto the baffle and then push the bottom back.
The grilles can be cleaned of dust by using an upholstery attachment of a
vacuum cleaner. To prevent damage to the tweeter, take care not to push
the cloth in toward the top of the grille.
SERVICE
If your system requires service, contact your authorized THIEL dealer. If

available at (606) 254-9427, Monday-Friday, 8:30 a.m. - 5:00 p.m. Eastern
