RBH A-815 In-ceiling Speaker


ADS Home Technologies has specifically chosen the RBH A815 for our 8″ in- ceiling speaker to be used for multi-room audio or distributed whole house audio.

Why would you chose the RBH 8″ over the 6-1/2 ” speaker?

It comes down to one word…


On all installations that demand maximum bass from an 8″ in-ceiling speaker, the A-815 is your workhorse.

The clarity, accuracy and performance of the A-615, with the the increased bass performance of a larger, more powerful woofer. With its round, slender, flush-trim mounting design, the A-815 is the perfect solution for in-ceiling applications requiring increased low-frequency performance.

You have to feel the weight of these things

It’s funny what people call a “good” in ceiling speaker. You can tell by how big of a magnet they use and how heavy the speaker is? How heavy is the A815? Believe it or not they are a whopping 5lbs each!
