Nice first approach. Be ready to make some adjustments as you go. My personal experience with GIK is they pushed too much absorption for my house of stereo design. It obviously was great at taking care of resonance, but it took me about a year to balance it with many diffusers to finally get the liveliness I had lost and wanted. Take a peak at my system where I describe the experience and square footage of absorbers vs. diffusers used. Enjoy the journey.
