GIK Acoustic Room Treatments
« on: November 05, 2019, 11:17:09 AM »
I've had 3 GIK Acoustic 242 Acoustic Panels in my theater for several years now. They made a noticeable difference putting them at the first reflection points.

Stay tuned as I install and report on several different GIK products including Monster Bass Traps, 244 Bass Traps, 
Tri-Trap © Corner Bass Traps, and GridFusor© acoustic sound diffusors.

Here they are installed. Did some tests tonight - these made a HUGE improvement on sound at the seats. Dialog is crisper / clearer, and the room sounds larger. Bass traps with scatter plates are adding to that larger sounding room effect I'd bet.

You should come check them out. I have another 10 bass traps coming in a few weeks too.

Craig,

I'm on vacation the week of Thanksgiving. Maybe sometime early in that week. Would that work for you?

Also, how did you affix them to the ceiling?

I'm gone that week unfortunately. I used double faced adhesive pads, but I don't trust those long term, so I toe nailed them at an angle with 2 1/2" finishing nails, into the drywall. 6 nails per panel. I tried the T pins they recommended, but they are too small and didn't inspire confidence ! The adhesive pads make getting them in place easy. The nails make sure they stay there !

The planets aren't aligning for us Craig. Maybe I can pry myself free for a few hours next week. I'm booked through Monday :(

Watched " Lucy " on 4K BR last night with friends that have never seen it, and one of the guests said he was amazed at how loud the soundtrack was ( reference + 1.5 ) but the sound never hurt his ears. And he felt the bass in his chest - haha ! The bass / LFE and sound in general has really improved. I think I'm finished. For now, other than maybe some further calibration.

So, I understand the need to put absorption in the first order reflections. 

Some questions:

1. where should diffusers go? 

2. Have the rules for diffuser placement changed with the Dolby Atmos spec? 

3. I've seen that most (?) folks put diffusers mainly in the back wall. I don't think I'll be putting acoustic panels in my ceiling. Would that change where else I should put diffusers?

I put diffusers on my ceiling based on recommendations from the guys at GIK. I'd reach out to them and see what they recommend.

You may want to try experimenting, if possible. 

For example, some of us have found that if you have speakers with good dispersion not absorbing the first reflection point actually adds a good amount of spaciousness.
