The QM-615 is the budget-minded answer for both residential and commercial in-ceiling speaker applications. The QM-615 employs a 6½-inch polygraphite woofer cone and a 1-inch swivel fabric dome tweeter for great sound. The QM-615 speaker is manufactured with high quality components and engineered to accurately reproduce music. Mounting flush to a wall or ceiling, architectural speakers are ideal for many applications where traditional speakers may be impractical or impossible. The QM-615 is especially well suited for distributing sound throughout the entire home and can be used to enhance surround sound systems. When properly installed, the QM-615 will provide you with years of entertainment pleasure.

The QM-615 speaker is packaged with an L-shaped quick installation and removal tool, grille adhesive, the hole cutout and paint mask templates. No other tools except wire strippers are required to install the QM-615 speaker once the hole has been cut in the ceiling or wall.

Painting the Speakers

A paint shield is included with your QM-615 speaker. This shield can be used to protect the speaker when painting the speaker rim (frame). If you plan to paint your speaker, we recommend that it be done prior to installation. If you decide to paint your speaker sometime in the future, it is best to remove it by following the simple instructions on page 5. When painting the speaker, the paint shields provided in the packaging must be installed in place of the grille. The grille can also be painted. Painting the speaker grille should be done with a paint sprayer set to fine. Remove the grille from the speaker, peel off the grille fabric on the back of the grille and set aside. Place the grille on a flat surface. Do not use a brush or roller on the speaker grille as it will clog the holes. This will greatly reduce the sound quality of the speakers. Do not paint the grille while attached to the speaker. Be sure to remove the paint shield from the speaker and replace the grille fabric to the back of the grille before reinstalling the grille and using the speakers.
