2.0 MODEL 107: THE LOUDSPEAKERS
2.1 UNPACKING, ASSEMBLY AND AFTERCARE
Spread the top and bottom carton flaps of the two largest cartons and lift off.
Unpack the two head assemblies. Identify the left and right markings and assembie with
the appropriate bass cabinet, carefully inserting the metal spigot into the receptacle on the
top of the bass cabinet. This will be a tight fit so take care to insert as vertically as
possible to avoid any damage to the bearing surfaces. Connect the flying lead/XLR plug to
the socket on the rear of the head assembly.
Unpack the head covers. Their use is optional. If you intend to use them we suggest you
place them on the speaker only after listening and positioning tests have been concluded.
Unpack K-UBE and identify the connection markings on the rear panel. Do not connect
the K-UBE to your amplifier at this time.

Aftercare
Your Model 107 loudspeakers are supplied in matched pairs of real wood veneer cabinets.
The cabinets should be treated with the same care with which you would treat fine
furniture, and the use of a good quality wax polish is recommended.
It is normal for walnut cabinets to darken and rosewood to lighten with the passing of time,
but locations in direct sunlight should, if possible, be avoided.
2.2 ROOM POSITION AND LISTENING WINDOW
The Model 107 is designed to stand on the floor, it does not require any other form of stand
or support. If the speaker is to be used on wood or tiled floor, use the feet as supplied.
On thick carpet, however, stability will be considerably improved by removing the caps
and using the pointed feet. Place the speaker in its chosen position and level it by
screwing the rear feet fully in and adjusting the front, using additional washers as
necessary to level the speaker.
Tighten the screws firmly when levelling up is completed. Only in rare cases of very
uneven floors should you need to adjust the rear feet.
The tonal quality and clarity of the reproduction, and above all, the sharpness of the stereo
image, are determined by the sound that reaches the listener directly, without reflection
from walls, floor or ceiling.
Reflections from nearby walls, mirrors, even the television set can spoil stereo definition by
confusing the primary image. Large items of soft furniture can cause absorption of
midrange and high frequencies.
The head assembly on Model 107 may be rotated to allow the midrange and high-frequency
directional information to be directed towards the listener independently of the position of
the bass cabinet. Thus it is possible to place the speaker to fit in with other furniture in
the room, or to be sited parallel to walls for neatness, whilst still allowing the listener to
benefit from optimum stereo performance.
Model 107 is capable of giving a stable stereo image over a wide listening area with an
unusually vivid sense of depth perspective. Since this is achieved in part by the shaping
and proportioning of the enclosures to permit sound to diffract smoothly, these benefits
may be impaired by reflections from nearby walls.
The loudspeakers should therefore ideally be stationed at least 1m from side walls and a
minimum of 50cm from any back wall.

The spacing between the two speakers, and the listening distance from the speakers is
important.
