appreciate the tighter bass and extended frequency response into the lower octaves that the use of a backbox (or blocking off the wall cavity) will provide. A hole cutting template is provided with the AT8000 Series Bracket Kit. The cutout for the speak- er must measure 9-3/4” x 17-1/4”.

Insulating the Wall Cavity

When it is not possible to use a backbox, good results can be achieved by treating the interior of the drywall cavity with Dynamat™ or a similar cabinet damping material. At least two linear feet of damp- ing material should be adhered to the rear wall and to the front wall (one foot above and one foot below the cutout) of the wall cavity. Additionally, insulating the wall cavity behind the speaker with fiberglass insulation (e.g., R-19 unbatted insulation) will improve performance. Try to keep the amount of insulation used for each speak- er equal, as bass output will be more con- sistent. Further improvement can be made by wedging a brace of 1x1 stock between

the front and rear walls, both above and below the cutout. Use care when inserting the brace, as too much pressure will create a bulge in the wall.

Speaker Placement

The AT8500 and AT8700 speakers feature a low diffraction midrange/tweeter array which employs Niles’ DSFG. This innova- tive driver configuration can be adjusted to provide optimum phase and frequency response at the listening position. Please read Positioning the Midrange/Tweeter Array under Installation of the Speaker and Grille in New or Existing Construction on page 17 before deciding on a final installation location for your AT8500 or AT8700 speakers.
