Gotham Quadratic Diffusers

Hi Joe: Ouch, I would also have canceled the order. You might want to try again. I live in Maine and I think the shipping came to somewhere around $35 . The Gothams are smaller than some of their prior diffusers. You can always place them in the cart and see what the shipping is before tapping the buy button. With the 10% discount I paid a little less than $400 for a pair.

@benzman very nice room and system. Yes I think one row across would produce some nice results for you. As  Joe Niels suggested I would contact GIK for a free consultation. 

Last week I added two more Quadratic Diffusers with disastrous results. All six of the shelf’s 40 pound rated dry wall anchors pulled out of the wall. Unfortunately ,my preamp was damaged. To prevent this from happening again , I added a third shelf bracket and using 9 six inch bolts secured them to the studs behind them. As an additional precaution to hold the diffusers securely in place, I used a combination of 75 pound rated picture wire , 4 carabiners and 5 six inch eyebolts. The piano wire is in a crossing pattern and the carabiners are attached to picture wire strung above the television attached to two eyebolts. The carabiners are so I can quickly take down the diffusers to watch the television. Yea it is a little bit of work to install and remove the diffusers but it is sonically worth it. I have posted a couple of pictures of my installation on my virtual systems page.

For those of you who are going to mount these directly to the wall I would not use the tiny screws included with the mounting bracket.

Hi Ozzy I am a trial and error guy when it comes to room acoustics. I have heard pros and cons about placing diffusers behind planars. GIK Acoustics could provide much better information. Personally ,once you get them dialed in and there are no sound gremlins, I would probably go with what you have in place.

I installed mine because the large tv behind the speakers was was worse than the flat wall because it was tilted slightly down affecting the stereo image as well as affecting sound quality. 

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 ?

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.
