SUSPENDING TL18-1 ENCLOSURES
The TL18-1 has been developed in conjunction
with the HS series of hanging hardware. The
HS kit allows the TL18-1 to be hung safely in a
variety of orientations. The combination of the
correct HS kits and TL18-1 enclosure has been
certified by an independent structural engineer
to be safe and secure. Each HS kit consists of
a steel tube, two brackets, two eyebolts and
the necessary fasteners. The installer must
assemble the HS kit by first drilling two holes
into the TL18-1 enclosure, in predefined posi-
tions, and then screwing the brackets onto the
steel tube, which passes through the enclo-
sure. Full instructions and hole locations are
included with each cabinet and HS kit. A single
TL18-1 requires a single HS3 to suspend it
horizontally, or a single HS1, vertically. How-
ever each cabinet, when hung in multiples,
requires two HS1s horizontally or two HS3s
vertically. A maximum of three cabinets can be
suspended in this manner. Horizontal is defined
by having the central EV logo in its correct
orientation. Full attention must be given to the
instructions and limitations in the HS kit in-
struction sheet.
FINISHING ProWood
TM
Finishing ProWood is simple and straight-
forward as long as a few things are under-
stood:
1. ProWood has been tested with a large
number of commercially available paints
with 100% success. However it is impos-
sible to test every paint available. Electro-
Voice therefore recommends that you test
a small area on the rear of the cabinet or
under the grille to check that there are no
adverse effects.
2. Ensure the surface is clean and free of
grease (use soapy water if necessary).
3. Any latex-, enamel-, or acrylic-based paint
can be used. The special top layer of
ProWood was developed in conjunction
with Pittsburgh Paints. They developed
their Manor Hall
®
Exterior House series of
paints to complement ProWood.

Electro-
Voice recommends the use of these paints
in adverse or tough situations.
4. Water-based latex paints in particular can
take a considerable time to dry fully. They
can be handled in a few hours but full
strength may not be achieved for a week,
particularly in damp or cool conditions.
5. The paint can be applied with a brush, roller
or spray. Care should be taken not to get
paint on the woofer cone.
6. Stain can be used to highlight the grain in the
ProWood or match real wood. The black
surface must be initially painted a light color.
A good approach is to use a stained var-
nish. Care should be taken when using
stain or stained varnish because it is impos-
sible to lighten a dark staining job without
repainting the enclosure in the light base
color and restaining.
USE OUTDOORS
If the TL18-1 is used outdoors or in adverse
conditions the following applies:
1. Direct rain and sunlight must be avoided.
For example, under the awning in a base-
ball stadium is fine but directly exposed to
the elements on top of the score board is
not.
2. The enclosures should be painted with a
high-quality exterior-grade paint (see Fin-
ishing ProWood section).
3. The enclosure should not, in any circum-
stances, be allowed to stand in water or be
exposed to damp material, such as damp
soil, for any period of time.
