3) Back off the coupling nut completely (Fig. 11) and thread on a backing nut with which to lock threads to the coupler.
Hold the coupler up to the hanger bolt to estimate the half way point of the coupler, and set the backing nut to
that height before re-installing the coupler and tightening it in place with a socket and an open end wrench.
Thread a backing nut onto the threaded rod (or an eyebolt) far enough so the rod can be threaded into the coupler
until it stops, having reached the hanger bolt inside. Now tighten up the backing nut on the rod to secure it from
turning, until it looks like (Fig. 4). Remember that the rod could otherwise be an eyebolt, if you are using the wire
rope suspension method, or a Hilti™ type fastener. Be sure to follow local building codes.
4) Always install and utilize all four points, and it should look like (Fig. 13). In this photo, the turnbuckles have been
added to the ends of the rods. The closed eyebolt on the turnbuckle has been removed and replaced with the
threaded rod. Note that the turnbuckle is stamped with an “L” to identify the load or live end. Observe the correct
assembly procedure from rod to eye-hook.
5) It’s now a fairly simple procedure to place the subwoofer onto the awaiting hooks. Two people, on two separate
ladders can now hoist the sub into place. When installed, it can easily be leveled with a few turns on the turnbuckles
(Fig. 14).
6) If no suitable point exists directly above the desired location, you can use wire rope or chain to make connections
that are not perpendicular to the suspension point(s). Under no circumstances should the angles /- 15
degrees from vertical. Make certain that you follow closely the instructions and regulations for the use of wire
rope for overhead suspension. Serious injury could result if guidelines and safety margins are not closely obeyed.
