Page 10: Enclosure Installation Procedure
ENCLOSURE INSTALLATION PROCEDURE Prepping the Work Area The steps and photos in this manual illustrate installation in new construction homes, however Fathom IWS-108 enclosures may also be installed in pre-existing construction applications. When working with pre-existing construction, you will need to open a stud bay and expose the studs on either side of the opening. For pre-existing construction installations, we recommend using masking tape and a drop cloth to protect the home’s interior from construction debris.
Page 11 Attach the Floor Support (Part D) To simplify installation, the enclosure is shipped with the following parts pre-attached: Part A – Wallboard Template Part B – Upper Stud Mount Part C – Lower Stud Mount Part D – Floor Support (shrink wrapped to enclosure) Place the enclosure on a supported surface/table and remove the shrink...
Page 12 Mark the Top L-Bracket Locations Place an L-Bracket on the top of the enclosure, with its foam padded section positioned against one stud. Mark a line along the L-Bracket’s edge to note its position. Repeat this procedure for the L-Bracket on the opposite side of the enclosure’s top.
Page 13 L-Bracket Installation Remove the enclosure from the wall cavity and place on a supported surface/table. Each L-Bracket includes two slotted openings for installation over two rows of predrilled pilot holes located at each end of the enclosure’s top and bottom. The slotted openings allow adjustment of the L-Brackets when mounting the enclosure within the wall cavity.
Page 14 Set the Enclosure’s Final Position Slide all four L-Brackets inward, then place the enclosure into the wall cavity, supported on the floor by the Enclosure/Floor Stand (Part D). Both Stud Mounts (Parts B & C) should be pressed against the stud faces. Using a level and the ends of the Stud Mounts (Parts B &...

(Figure 14) At the enclosure’s bottom, slide each L-Bracket outward and, while holding upward against the enclosure’s bottom, install six #8 x 1.25-inch wafer Figure 14 head screws per L-Bracket to secure to...
Page 16 Route the Speaker Cable Route speaker cable into the bottom of the wall cavity through an adjacent stud and remove the outer jacketing to expose the individual wires. Two rubber covers are included to insulate the speaker terminals. Feed the individual wires through each rubber cover and remove the wire insulation.
Page 17 Foam Gasket Installation The included energy absorbing adhesive foam gasket strip is used to reduce the potential for noise and vibration between the studs and wallboard, especially in installations with metal stud construction. Remove the backing and firmly press the foam gasket strip to all stud Figure 23 faces surrounding the wall cavity.
Page 18 GRILLE INSTALLATION PROCEDURE Before you Begin The following instructions assume the IWS Enclosure has already been installed. The Grille Assembly The grille assembly is comprised of a removable outer metal mesh and grille tray. The grille assembly should be installed only after the surrounding wallboard and grille assembly have been painted and the room’s interior is free of construction debris.
Page 19: Notes
Grille Assembly Installation With the Wallboard Template (Part A) removed, test fit the grille tray by inserting it into the opening with the JL Audio logo positioned at the bottom. The grille (Figure 2) tray’s outer edge should make contact with the outer wallboard surface.
