Gotham Quadratic Diffusers


I have a dedicated audio room that doubles as a home theater. I have desired to put diffusers on the wall behind my speakers since I built the room but a large screen television has stood in the way and I have a lot of gear with cables below it taking up floor space making a floor installation difficult.When I saw the GIK Gotham quadratic diffusers, I thought I could have my cake and eat it too.

My initial plan was to use heavy gauge wire and hang them off the television but I was a little uncomfortable with the additional weight on the wall rack that was right at it’s weight limits with the heavy plasma tv attached to it. I looked at premade shelves but couldn’t find anything with the dimensions I needed. A trip to my local Lowe’s solved the problem. I purchased a pair of heavy duty shelf brackets and a painted 3 foot shelf. I also bought heavy duty metal dry wall anchors which don’t require drilling to install just a Phillips head screw driver. The openings for screws on the shelf brackets were a little wider than the drywall screws so I purchased some flat washers. Total cost was around $40. Installation was easy and the diffusers fit perfectly on the shelf.

Shortly after installation one of my Audiophile buddies visited for a couple of days. He knows how my system sounds as good as I do. After a couple hours of listening I asked for his impressions without telling him what I thought. He heard the same things as I did with the most noticeable being vocals and soundstage. Vocals especially the lead were more finely delineated and the soundstage got wider. With the vocals it sounds like you have moved two or three rows closer to the stage. I am very impressed with the results and plan to purchase another pair.

For anyone who may be interested in these diffusers GIK has a 10% discount through the 15th of this month. Outside of being a customer , I have absolutely no affiliation with this company.

Iwin,

Do you think the diffusors would work well behind Planar speakers?

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.

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.
