What are the benefits of Butyl Rubber Surround?

Much more expensive with almost double the shelf life of foam, butyl rubber has been the choice of speaker designers looking to optimize the sound based upon materials that go together. The Surround is just one of the integral parts of the speaker's motor structure. Butyl rubber allows the use of unique cone materials like Kevlar and mineral-filled composites. Butyl Rubber gives the speaker more excursion capability featuring a deeper bass with a wider frequency response, and its shelf life is closer to 25 years compared to the foam at 12 to 15 years.

What Gauge Wire Should I Use for my In-ceiling Speakers?

For runs up to 100 feet for background music, 16-gauge will be fine. If the run is approaching or exceeding 100 feet, use 14-gauge wire. OSD Audio offers CL3/FT4 cable that is UL (fire) rated for all residential and most commercial in-wall and in-ceiling applications.

Paint the Grilles for a Custom Touch!

Many of our customers like to paint the grille of their in-ceiling speakers to match their room décor. Painting the grilles/trim won’t harm your speakers but be sure to use spray paint; never a brush. Brushing the grilles can clog the holes and interfere with sound quality. We also recommend using a fine spray paint gun, the inexpensive kind that you can pick up at your local hardware store. Our in-ceiling speakers also come with a paint shield to help guide you.

For a retrofit installation, no construction bracket is needed.
Please note: Use cut-out diameter according to the bullet point on the website.
