Speaker Fine-Tuning
The particular acoustics of a room influence the sound of every speaker. Because each room has its
own unique setup, the positioning of speakers for optimal sound quality is different in each case, and
reflections of sound from wall, floor, and ceiling surfaces play an especially important role. Large
rooms with few objects in them and many flat surfaces tend to produce prominent resonances and
reverberation, which make the music sound bright and diffuse. In contrast, a heavily damped room
with a lot of furniture and many soft surfaces produces more of a dark, lifeless sound impression.
Depending on the design of the room and the positioning of the speakers, the influences of furniture,
curtains, and other objects can very negatively affect the quality of your listening experience.
Model No.7 can be adjusted to the acoustic properties of the room where it is employed or to
particular positioning restrictions. For this purpose there are two jumpers on the rear terminal panel of
the speakers for adjusting the bass and treble response.
