Note

Avoid distortion.

Raise the level cautiously if the loudspeaker diameter is too small.

The tonal response may be- come too thin and aggressive. Pay attention to the fundamen- tal tone range of the music.

Reproduction must not be- come too faint.

Tonal response too weak.

Avoid a sharp tonal response. Loud hissing impairs the quali- ty.
