2. Handling
The Linear Three is a relatively delicate precision
engineered product that can be damaged by
inappropriate handling. It is also large and heavy.
Please take great care therefore when unpacking
or moving the speakers. Plan any handling in
advance of carrying it out - ideally with a second
person to help. Please take care when unpacking
or moving the speakers not to touch either of the
drivers. Damage to a driver will at best degrade a
Linear Three’s performance and at worst result in
its complete failure.
The enclosure surfaces should also be handled
sympathetically. Any cleaning should only require a
soft cloth, slightly dampened if necessary. Be wary
of using any polishes or solvent based cleaning
agents.
The packaging should be retained for future use.
3. Installation
The Linear Three is a floor-standing loudspeaker intended to be positioned
clear of room boundaries and coupled to the supporting floor through spikes.
If spikes are inappropriate for your floor covering, metal protection pads,
coins for example, maybe used between the spike and the floor.
The separately packed plinths must be attached to the botttom of each Linear
Three before they can be installed. Invert each speaker onto a “protective”
piece of material so as not to damage the top of the cabinet. Insert the four
screws (supplied in the packaging) through the holes in the plinth and line
them up with the pilot holes in the cabinet. Screw them into the cabinet
making sure that the plinth is firmly attacthed. Failure firmly to attach the
plinths will degrade the speakers’ performance.
Four M8 floor spikes and lock-nuts are supplied within the Linear Three
packaging. The spikes and lock-nuts should be fitted to the underside of each
Linear Three plinth once the speaker has been moved near its final location.
Carefully lay the speaker on its back to gain access to the tapped holes in the
plinth. Screw a spike and lock-nut into each hole leaving a length of spike
extending beyond the lock-nut such that once the speaker is upright the
lock-nuts will “float” just above the floor covering.
Tighten three of the lock-nuts on each speaker with a 13mm spanner leaving
one lock-nut finger-tight to aid adjustment once the speaker is upright in its
final position. Once the final position of each speaker has been established
adjust the length of the loose spike such that the speaker is vertical and does
not rock. If the floor is particularly uneven it may be necessary to loosen one
of the tightened spikes to ensure that the speaker can be levelled.
Finally, tighten all loose lock-nuts. It may be necessary to re-adjust to
minimise rock once the speaker has settled on the floor. Take care when
installing floor spikes. They are sharp and can cause injury or pierce electrical
cables.
The Linear Three can be “mass-loaded” in a compartment at the bottom of
the cabinet. Mass loading can significantly improve the performance of the
speaker. The compartment can be filled with washed, fully dried and non
salt contaminated sand, or suitable metal chips, via the access hole in the
the back panel. A plastic bung is provided to seal the cabinet. If you decide
not to mass-load the speakers, we still recommend fitting the plastic bung
to avoid unwanted resonance. Be aware that the plastic bung has not been
designed to be removable after insertion. You may wish to use a temporary
removable plug until you have made a decision whether to mass-load.
