Thank you for purchasing a Stealth Acoustics LineaResponse invisible speaker. This speaker is constructed in
the USA with high quality materials. Built in circuit protection (on most models) adds reliability and piece of mind.
With proper installation and care it will last a lifetime.

TIPS & BEST PRACTICES
THESE INSTRUCTIONS ARE IMPORTANT!
Reviewing and understanding these instructions prior to installation is a simple way to help prevent improper
installation which can void the warrantee and lead to a visible installation, poor speaker performance, damage to
the speakers, and possible costly repair/renishing expenses.
INFORM THE CONTRACTOR AND CREW
It is very important that the contractor and wall nishing crew are made aware of the speakers and have reviewed
this document and the installation videos available at StealthAcoustics.com prior to arrival on site. Although the

PLANNING SPEAKER PLACEMENT

easier.
Start with standard speaker planning techniques for each room, but know that LineaResponse speakers can be relocated
around architectural features or hidden utility services such as plumbing or ducting, etc. Each speaker comes with a protective
paper overlay that can be used as a planning tool. Arrange and attach the overlays to the wallboard/framing when planning

ACOUSTIC ISOLATION PRACTICES
SUBWOOFERS
It is important that the location for Stealth invisible subwoofers be chosen carefully. The backside low frequency output of
these panels is roughly equivalent to the front side output and as such, sound can penetrate through the rear wall behind the
speaker into the adjacent space. Ideally, subwoofers should be mounted on exterior walls, or on interior walls connected
to less used spaces (like laundry rooms, closets, etc) to avoid low frequency bleed-through to an adjacent room.
It takes mass to attenuate sound energy and the lower the frequency, the more mass required. Additional sound
dampening can be achieved by adding additional mass like gypsum wallboard to wall and ceiling structures around the

CHOOSING AN INSTALLATION LOCATION

condominium.
Sound isolation is a combination of mechanical and acoustical properties. Stealth speakers have little mechanical
vibration at the attachment points, so the primary isolation issues with Stealth speakers are acoustical.
Whenever possible, place speakers on outside walls, non-party walls, or adjacent to interstitial spaces
closets, laundry rooms, etc.) This is especially true for subwoofers where the backside low frequency output is roughly
equivalent to the front side output and as such, sound can penetrate through the rear wall behind the speaker into
adjacent spaces.
Walls and ceilings near Stealth speakers need to be rmly constructed and free of structural items that could
rattle
Air-gaps greatly reduce sound isolation.
Stealth recommends the use of a Back Box sealed enclosure with each speaker .Sealed

time of the base coat of joint compound. It is critical that each coat of joint compound is completely dry before the next
layer is applied. Any moisture retained in the base layer will continue to slowly dry and shrink slightly under the subsequent
layers of joint compound. This type of cracking does not typically appear at the seam between the wallboard and speaker,
The best way to prevent this type of cracking is to allow additional 24 hours of drying time for each layer of joint
compound, especially in areas where the construction environment is cold or damp. THE USE OF HOT MUD OR
