Control 85M/88M Mushroom Landscape Speaker
Installation Instructions
Before nal assembly and installation of the Landsape speaker, it is important to prepare the installation site. The speaker is
designed to be able to sit below grade, with the lower half burried in the soil no deeper than the boundary point where the
two parts of the speaker meet. Another installation method is to place the speaker on the surface and use ground cover
materials to “berm up” to the boundary between the two sections, being careful not to cover the ared waveguide in the upper
half of the speaker, or the speaker can be installed on the top surface of wooden decks or cement slabs. There are three
recessed pathways on the bottom of the speaker to allow for entrance and exit when using mutiple speakers on distributed
lines.
Anchoring the speaker for stability and security can be accomplished using after-market stakes placed through one, two or all
three pre-drilled holes located at the base of each of the legs on the bottom section.

The second gland nut can be installed by drilling a 22 mm
(7/8 in, 0.875 in) hole on the side of the bottom half of the
enclosure, in one of three recesses on the underside of the
enclosure, or other locations as needed, while taking care
that the location chosen does not interfere with the
locking parts so both halfs of the enclosure will mate and
close properly.
6
Install the gland nut into the hole as shown
above in #6 and feed external wire from
outside through the gland nut and up through
the center hole in the lower half of the speaker
as shown above.
IMPORTANT: WIRE SIZE
** To achieve a watertight
seal with these gland nuts,
use only round jacketed
cable with outside diameter
(O.D.) between 4.0mm (0.16”)
and 9.0 mm (0.36”).
Attach one of the two included Gland Nuts into the open
hole on the seal plate as shown above.
7
Continue to extend external wire up through the gland
nut installed on the seal plate and attach to pre-existing
wires from the top section of the speaker with included
gel-lled wire nuts.
