@benzman Yes they will help. I suggest you put 2 under TV and 1 on each side of the TV. The one’s under the TV try leaving 6 to 12 inches between them.
I’m a firm believer in how helpful acoustic materials can improve a room.

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.

Greetings, I’m glad you had positive results with the Quad Diffuser’s. I ordered a pair from GIK a few months ago. I was hesitant about shipping costs. I placed my order and it showed that shipping cost was $25.00.. I was very happy with that price. A week later I received a message from them stating there was a problem with my order. The shipping cost was Not $25.00 it was $228.25…. I was shocked. I kinda knew that $25 was to good to be true. So I cancelled my order. I should have just sucked it up and paid the shipping. I probably will order a set in the near future. It’s the last item I need for my room. I live in Anchorage Alaska, so everything costs more. It’s a pet peeve of mine what shipping charges are up here. Joe Nies |
Have all ceilings and walls treated. Using different absorption and diffusion methods. Also have tube bass traps. I eventually will purchase a pair to put the finishing touch on my room acoustics. Joe Nies |
@christianb5s4 Contact GIK they can probably make the diffusers any size you want. They also offer free consultation. Joe Nies |
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. Be careful if you hang them. They will cause damage if they fall as @lwin has described above.

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. |
