Diffuser decision for ceiling

Would like to get some feedback and info. 

Trying to stick with Vicoustic products since its more easily available here in Canada.

My room is 19 x 14 and the ceiling height is just shy of 7 1/2 ft. (7 "4 roughly).

I already have acoustic panels setup in the room. I already have plans to add diffusion in the back and front walls based on recommendations. 

The last piece I'm missing is the ceiling. 

I kind of rushed and had bought a used set of Vicoustic Multifuser DC2 in order to use. My plan was to install 3 in one line covering the Left, Center and Right channel speakers first reflection point on the ceiling.

However, after using ChatGPT, googling and got some advice from a local store, they said that I would be better off using the Vicoustic VicPattern Ultra Wavewood MKII. Both DC2 and Wavewood would be installed flush to the ceiling.

Chatgpt suggested leaving 2-4 inches spacing in between them versus having them stuck all together. 

What does everyone think? Before I invest in the ceiling installation. 

I have floor standing speakers SF Olympica III and my center is a SF Sonetto CII. Let me know if more info is needed, thanks

I use GIK absorption for first reflections on the walls and ceiling and a thick wool cut-pile rug with pad for the floor. I have Ultra Wavewood Diffusers on the walls and DC3 diffusers on the ceiling to further treat the room. I use 3M Dual Lock strips to hang lighter panels on the ceiling. Be aware that you need a certain distance between you and diffusers for them to work properly.

I agree that space between treatments is not bad.

Good luck!

I mounted 4 Wavewood panels on 8 ' ceiling using adhesive and a safety hook.  

They are centered on a line from Sonus Faber  Nova 3 and listening position using the first reflection point of tweeters.  It made a big improvement.

Are you up for trying something low cost, effective, and fun?

Buy two packages of Golden Sound Acoustic Discs.  Use one on the ceiling corners and experiment with the others on speakers, side walls and rack.       

Can't miss, for less than $300!

Thanks everyone, @davejaz  that looks really good!

Yeah I spoke to a acoustic treatment specialist yesterday, he advised i stick with the Vicoustic Multifuser DC2. He did suggest i try to take some measurements before and after. Which may take me awhile to learn REW and how to use it. So Ill have to see. 

Another good suggestion is I can use maybe some industrial Velcro and not have to buy the whole railing Vicoustic system.

I would like to see the studies that are associated with the statement: "Scientific measurement shows that Acoustic Discs reduce cumulative spectral decay from 30 to 50 percent between 80 to 15000 Hz." I could not find any on their website but perhaps I just didn't look closely enough.

GIK and Vicoustics have data/graphs that demonstrate their effects and effectiveness. I don't think you should settle for less when it comes to acoustic treatment. 

More to discover
