The ECS Edgeless In-Ceiling Speakers are designed to be flush mounted in
walls or ceilings. For optimal acoustical performance, simply follow these
guidelines:

The ECS Edgeless In-Ceilingl Speaker grilles are paintable and can accept
virtuallyanytypeofpaint.Westronglyrecommendthefollowing:
1.Removethegrillesfromthespeakerspriortopaintingthem.
2. Thin the paint prior to application, if needed. Spray and roller paint
applications typically provide the best results. Note that you may need to
apply multiple thin layers of paint to achieve the desired shade without

3. Let the painted grilles fully dry before mounting them back on the
speakers.
