Sound optimization
Besides having constant directivity, the 8c has a very flat power
response. These traits make it relatively insensitive to acoustic
imperfections of the listening room.
Carefully positioning and configuring the 8c will result in
60°
remarkable in-room performance.
Basic triangle
When using 8c's in a two–channel stereo setup, position them
in an equilateral triangle with your listening position.
A two–channel stereo setup
Listening distance
The normal equalizer settings for the 8c yield a perfectly flat
> 1 M
response at listening distances of 1 metre (3'3") or more.
The strength of the (accurate) direct sound from your monitors
decreases by 6 dB per doubling of the listening distance.
However, the strength of the (uncorrelated) reverberant sound
Recommended listening distance
in your room is more or less constant. As such, choosing a
smaller listening distance will increase the ratio of direct to
reverberant sound, which increases clearity. Listening from a
larger distance makes the soundscape more spacious.
Listening height
The reference axis of the 8c is perpendicular to the baffle and
equidistant to the woofer and tweeter axes, 26.5 cm from the
30°
bottom. The loudspeakers should ideally be positioned in such
Recommended listening height
a manner that the axis is near ear height. However, as long
as you are within around 15° of the vertical reference axis,
variations in frequency response are near imperceptible.
Toe-in
The horizontal on and off axis frequency responses of the 8c
are very similar; the 8c sounds virtually the same whether
you're straight in front of it or at an angle of up to 45°. As such,
the direct sound will not be significantly affected by toeing the
loudspeakers in (aiming them at or in front of your listening
position) or out (aiming them so that they are parallel to each
other). This, in turn, allows you to adjust stereo imaging without
compromising the spectral balance of the sound.
A setup without toe–in
Generally speaking, more toe–in will yield a more focused,
precise, and drier sound by reducing the strength of lateral
