6. BUILD THE WOODEN STAND
6a. Begin by placing 2 of
the 12" wood pieces into an
X shape.
Secure with two 2½" deck
screws. Repeat to make a
second X with the remaining
pieces. Connect the X brackets to one another with the
remaining 2× 4, using the
deck screws.

6b. Place the conduit on the
stand with the holes pointing
up. Make certain the area
around the conduit is at least
5' — that’s 5 feet — away from
any combustible materials on
all sides, as well as above it.

TIP: Using the optional
pipe flashing boot (the
“witch hat”) is an easy way
to get a good connection.
Use a knife to cut appropriately sized holes, then
couple the conduit to the
loudspeaker. Hot glue might
help to secure the speaker
in the boot.
7.CONNECT SPEAKER TO TUBE
7a. Place the loudspeaker
firmly against one of the balloons and affix the speaker
to the end of the conduit. The
quality of this connection has
a large impact on how well
the Rubens tube works; you
may need to use duct tape
or hot glue, or form a flexible
rubber gasket to affix the
speaker securely.

now ready to use!
