Temporary InstallationsUser’s Guide
Retaining plate locking bolt
removed, spacer block placed
aside for future use
Threaded insert for retaining
plate locking bolt
Loosen pivot bolt so
retaining plate swings freely
During the experimental stage of your TubeTrap positioning and HF tuning, you may wish to utilize the Positioning Tab for centering and pivoting of the TubeTrap to ease disassembly.
*Also recommended for show installations, for speed of setup and tear-down.
Positioning tab pushed into
fastener hole
Philips drive screwdriver
Retaining plate swung into
position, both bolts tightened
Philips drive screwdriver
Positioning tab protrudes
~3/8" from plate, providing a
pivot point for your
TubeTrap HF tuning
Nylon gliders permit very
low-friction rotation of
TubeTrap for HF tuning

Retaining plate is in factory-
conditions (pivot bolt tight,
positioning tab in stowed location)
Retaining plate nut tightened
onto spacer block
Rubber compression gasket
placed against flat washer
Flat washer placed against
connecting bolt head
Once the positions of your TubeTraps have been established, our connecting bolt will ensure a robust connection between your Octagon Base and TubeTrap. This will protect against any shifting or rattling under heavy SPL listening. The rubber
compression gasket has been designed to allow fine tuning of HF response while the connection nut is in use.
With TubeTrap inverted,
Octagon Base is placed upon
end cap and Connecting Bolt
Assembly is inserted into
fastener hole. Bolt is turned
using flat head screwdriver
until resistance is met.
Lower portion of threading is
lightly fouled to permit secure
fastening at correct rotational
position
Connecting Bolt Assembly
Test the connection by
attempting to rotate the
Octagon Base relative to the
TubeTrap. The Base should
spin with moderate
resistance, and the
Connection Bolt should not
spin.
Spins with resistance
Does not spin
PROBLEM: base will not spinà loosen Connection Bolt
PROBLEM: Connection Bolt rotatesà tighten Connection Bolt
PROBLEM: base wobblesà tighten Connection Bolt

Installed ConditionsUser’s Guide
TubeTrap is mounted and
centered upon the Octagon Base
Architectural styling blends well
with common many room features
Reflector button indicates
the orientation of strongest
HF response
Having used either method of Octagon Base attachment, you should now be left with a handsome and adjustable TubeTrap presentation. Adjust TubeTrap HF tuning by simply rotating the unit by hand. The silver button(s) indicate the center of the HF diffusive half of the cylinder, whereby aiming the button directly at the listening position will result in the strongest HF
response.
Rubber feet allow secure
placement upon hard and
carpeted flooring
Finished Assembly
Can I stack multiple TubeTraps upon the Octagon Base?à Yes, the units are rated in excess of three times the weight of the corresponding TubeTrap model at 48" height.
Is there a front or a back to the Octagon Base?à No, all orientations are mechanically and acoustically equivalent. However, due to their hand-made nature, one
or more sides may be visually superior to the others. Select your favorite to face into the room.
Can I use Octagon Bases in room corners, even though the TubeTraps will not be tucked fully against each wall?à Yes, the wavelengths we seek to trap are quite large and their corresponding pressure zones are large as well.
In many cases, placement of TubeTraps approximately 1-3 inches from room corners results in more effective bass
trapping than fully against the walls.
If in doubt about your particular room and sound system, please call 1-800-ASC-Tube for detailed assistance.
