Where are the Carboard Tubes
Posted by jdbsound on August 28, 2017
Churches use a lot of Cardboard Tubes in acoustical room fixes because they are very effective in getting the room performance they want and need. Cardboard Tube not only outperform all other acoustical products in churches but they are also the most affordable. There is nothing that can do what half-round tubes can do, even at 40 times the cost.
Ok then, what if you don’t like the look of cardboard tubes around your worship space. Here is an option some churches have been willing to spend a little extra for.
These look like standard 5 inch deep absorbing panels. They are not. These are Sono Tubes mounted in a wooden frame and covered with cloth.
The cloth was an added expense and it was worth it. The fire rated cloth is expensive and before covering the panels, you want to make sure the acoustical system is going to work and work it did. The church is very happy with the results and they are enjoying the room.
This is what the installation looked like before it was covered. The wooden frame has no effect on the performance of the half round tubes. The cloth only affects frequencies above 10,000 Hertz which means they have no effect on speech or music. In this installation, three sizes of tubes were used.
At the bottom is a huge video wall screen. On the wall are the Sono Tubes. Yes, the tubes will work behind a vinyl screen. If you notice the pattern of the diffusers on the wall. that pattern was needed to control lower mids and bass sound energy. This pattern was pretested in our test room.
Here is the finished installation of the video system. It takes three projectors for each screen. The center screen is a video wall.
