Vertical Suspension of the HPR152i and HPR153i
loudspeakers
Install Two Top Surface Eyebolts
1- On the top front corners of the enclosure, locate the rubber inserts which pro-
tect the enclosure’s threads. Remove the rubber inserts.
2- Place one conical spring washer and one eyebolt standoff onto the threaded
portion of an eyebolt and carefully thread the eyebolt assembly into the enclo-
sure’s threads. Repeat for remaining front, top corner.
•Note! Be sure to tighten each eyebolt until
shoulder is snug against the spring washer
and each eyebolt standoff is snug against the
enclosure. Tighten the eyebolts down and then
continue to rotate until they are positioned as
desired.
Install One Pull-back Eyebolt
At the rear of the enclosures, just below the amplifier module is a M10 flat-head
screw which must be removed and have an eyebolt installed in its place (6mm
hex wrench needed).
1- Remove the factory installed bolt using a 6mm hex wrench.
2- Thread an eyebolt into the enclosure’s threaded insert; do not use a flat
washer or an eyebolt standoff on the pull-back eyebolt.
•Note! Be sure to tighten bolt until shoulder is
snug against the side of the enclosure. Tighten
the eyebolt down and then continue to rotate
until it is positioned as desired.
•Do not suspend the HPR152i or HPR153i loud-
speaker horizontally under any conditions! The
HPR152i and HPR153i loudspeakers are
designed for vertical suspension only!
