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 

HS1’s horizontally or

 two

 HS3’s

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.

1

  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.
