average efficiency (87dB) and therefore requires a normal amount of power.
3) A small room will need less power for a given loudness level than a large room. A very small room of 1000 cu ft (11' x
11' with an 8' ceiling) will require about half the power of an average size room. A large room of 6000 cu ft (20' x 30' with a
10' ceiling) will require twice the average power. If the listening room is connected to another room by a large open area, the
required power will increase, but not by the amount of the combined room volume. If the room has a "dropped" ceiling with
light panels, the ceiling will be almost transparent acoustically and the space above the ceiling should be added. If the panels
are heavy they will act as a more normal ceiling.
With all this in mind, a person who doesn't like to play music very loudly and has a small room can get quality sound with
as little as 50 watts whereas a person who sometimes likes to play loudly and has a large room may need 300 watts or more.
CABINET FINISH CARE
THIEL wood cabinets possess a high quality lacquer finish that is both beautiful and durable. However, any wood finish can
be damaged by excessive moisture, dryness, or direct sunlight. When cleaning your speakers, avoid using oils, waxes, or
polishes that contain silicone, such as Pledge or Johnson's. We recommend using Endust. Non-wood laminate cabinets may
be cleaned with a glass-type cleaner and a soft cloth.
GRILLE
The PCS grille is is attached magnetically to the front of the speaker. The 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 the grille frame away from the front of the
speaker. When replacing the grille, line up the grille's top two magnetic discs with the top two tweeter/midrange driver screw
holes and the grille's bottom two magnetic discs with the bottom two woofer screw holes.
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.
