I have 8 GIK 244 panels. Made a big difference for me, and the price was very reasonable. Good, friendly service too.
I know both companies are popular hear and have a good reputation. I was looking to know what the differences were between the products.
ATS acoustics makes similar products at some of the cheapest prices I've found. Good quality - i use their panels.
