Anyone use GIK for room treatments

[Rmax]

Hi @Simon_Arnold3,

I am using GIK bass trap Impression serie. The thicker ones. My wife is liking them very much because of the front panel decoration. Otherwise I have also Astri panels (3 bass trap, 3 diffusion and 3 absorption). I have given more details into that post:

Hi guys, Not sure if I should post here first, as before trying to make a filter I am just trying to use at best my acoustic panels. I have two AStri diffusion panels on front wall (actually a large window) in between the speakers. Two AStri bass trap on top of Ikea Kallax shelves both left and right on the front wall. Two GIK bass trap with diffusion panel on left and right walls between the Ikea Kallax and the speakers. At first reflection point I have two absorption panels on the left from…

The results for the moment in terms of room passive correction only are in that post:

Hi @alec_eiffel, @Magnus, I have followed your recommendations and also read through the “pdao” threads on Forum-Hifi for which @alec_eiffel had put a link in that topic before. Most importantly I have been able to convince my wife to open the large window doors between the Home Theater room and the Hi-Fi room. The opening is 44% of the surface. It is dead center. The volume of the room has been multiplied by 2.4! It is now 92m3: L925cm, l375cm and H265. I have made following measurements. P…

My Home theater room part is not having any treatment. I believe I will wait to have the budget to buy RPG Modex Corner. From all the searches I have made, they are expensive but the best approach in bass trapping in a contained space because of their membrane system.

GIK are very reasonable in price but not well recognized by professionals for instance. When looking to their technical data it looks like they are absorbing also on the higher frequency. These are the data for the GIK 244 bass trap:

The Astri bass trap for instance which is also very reasonable in price seems more focused below 100Hz.

Astri data:

I mean for bass trap if you want to be efficient you never have enough in typical small rooms that we have at home.

I would think diffusion and absoprtion panels are easier to find at smaller cost such as the GIK ones but for bass trap I would tend to spend more money if I could.

From my post you see that I have a pretty good response in my stereo system room, but I also have a lot of furniture that are helping partly. I guess also this could be linked with my speakers themselves, as the room is only responding to a signal. I had seen in some of my speakers review that they are quite forgiving even in non treated rooms, so I guess even better when treated!

Because it seem to work quite smoothly for me directly, I am afraid I did not do loads of testing with and without and also with the Astri vs GIK to compare.

So all in all I believe GIK panels are good for the money and especially with the Impression serie very WAF compatible. You will not get wrong with them, but if you have a serious issue with low frequency then you may want to start directly with something much more efficient as bass trap.
