Back Boxes
Studio Series speakers can be installed with back boxes in order to reduce sound transmission into adjacent
rooms or to satisfy any local statutory building regulations. If back boxes are to be used they must be installed
within the walls and ceilings before the drywall (plasterboard) is affixed to the studs or joists. Alternatively, the
existing drywall (plasterboard) around each speaker installation position may be removed to enable a back box to
be installed, and reinstated following back box installation. Further information on Dynaudio back boxes can be
found at dynaudio.com.
Generic back boxes from alternative manufacturers can be used, or back boxes may be constructed on site. In
either case, Studio Series speakers require a 22 Litre (0.8 ft3) minimum back box volume in order to reach their
full audio performance potential.
Before commencing any Studio Series installation you must be sure that the wall and ceiling positions chosen are
free of obstructions such as pipe work, ducting or wiring that might interfere with the installation. Stud-finding, pipe
detecting and wire detecting tools can help map the wall construction and identify any potential obstructions.

Check with local building regulations for fire safety. In some areas it is required to have a
fire-rated back box as a fire safety barrier. Ensure that the surrounding materials meet
the flammability Class 5VA. A fire rated metal back box must have a minimum uncoated
thickness of 1.35 mm.
