Gotham Quadratic Diffusers

Greetings 

Well I finally sucked it up and purchased 4 of the Quads. I really like how they look. They work a bit better than the Slot Diffuser/Absorption that were behind my speakers. I waited too many years to get this type of diffuser and I think that’s why I was a bit disappointed. 
I agree with @lwin about the mounting brackets that the Quads come with. They seem to small to hang them. I installed L brackets on the Quads and then secured them to the 6 inch shelf that runs along my walls. They will not fall? I think they weigh about 20 pounds each? I posted pictures on my virtual system.

Be careful if you hang them. They will cause damage if they fall as @lwin has described above.

Hi Joe hopefully the shipping was less than you expected. Give the diffusers some time as they don’t need a break in but your ears might take a little time to adjust to what they are doing. Are you going to paint them ?

Hello @lwin 

No I didn’t get any break on the shipping. It cost me $456.50 to ship the 2 boxes to me. Outrageous shipping costs but I really wanted this type of diffuser for a very long time. Shipping cost are the main reason I don’t have a lot of new toys. I have been buying my latest acoustic panel’s from Amazon. I get kinda free shipping as a prime member. No matter how big the shipping box is.

I have thought of painting, staining or sealing them. I’m not sure how your diffusers arrived but mine had the overwhelming smell of freshly cut wood. I purchased therm at the end of May. It has taken over 3 months for the smell of freshly cut wood to diminish. I have been running an air purifier in my room almost 24 hours a day to help get the smell to calm down. I thought that the diffusers were made out of aged air dried wood but this was not the case. I hope they don’t warp or crack as they dry out more.

I got tired of climbing up on my equipment rack to take down or reinstall the diffusers. Eventually ,I would probably drop one ,take a tumble or both. I wanted to be able to slide them out of the way. Barn door sliders wouldn’t work due to the ductwork on the wall. Pocket door hardware would work but I needed hardware that I was confident that would support the load. Amazon has Jubest pocket door hardware and the commercial grade will support up to 220 pounds compared to something like 74 on the regular. I ordered two 5 foot sets. I used Spax 2 1/2 inch multi-purpose construction screws to secure the rails to the studs. I purchased the screws at Lowe’s. You will have to do a little drilling of the rails to properly attach them to the ceiling. You do not want to attach the rails to the drywall only as this could result in a disaster.On the outside of each rail I installed a cotter pin so the units won’t roll off. I also purchased two 8 foot 4 inch by 1 inch pine boards again obtained from Lowe’s. I cut these in half and used the two pieces to secure 2 stacked diffusers using the Spax screws. I spray painted everything and installed the rollers at the top of the boards. Once this was done, I slid the completed units into the tracks. I would recommend help with this install if you can get it as the rollers rotate freely and an extra pair of hands would make installation much easier.

I have posted a couple of pictures on my system page for those who may be interested on how the project turned out. Also, I will gladly answer any questions.
