Hello all,
I am new to this forum, hopefully I am posting in the right place.
I am building a 12' x 18' x 9' dedicated home theater and I am making my own panels to absorb the early reflections from the front LCR speakers off of the walls and ceiling.
I have made the following changes from the original: * My panels are more compact for fitting closer together and so that they intrude on the room as little as possible. * My panels have a back on them so that they could later be removed and re-used.
I am favoring the "heavy duty mid/high absorber" because my main focus is the high-range reflections from the front speakers.
I will have these in the following locations: * Up to ten on the ceiling making a 10' x 8' area * Up to six on the left and right making 4' x 6' panels * Up to six in front making 4' x 4' panels behind the LCR * Two in the rear center making a 4' x 4' behind the main seat
I am interested in hearing if people think this design is good or not. If maybe I have compromized the original in some way with my changes or how it might be improved upon.
Note that this is not the only sound material in the room, there is additional corner treatment and a large bass trap, as well as diffusers in the rear.

What I see in your plans looks fine. Really good in fact. But you should plan to make some low-bass versions too. Or maybe see which version is more appropriate based on the width of your room for panels at reflection points.

It is good to see that Ethan is ok with the combination bass/mid high absorber.
It looks like that main difference with your mid high absorber is the 1" gap instead of the 2" gap. The smaller gap will decrease its absorption at frequencies below 500hz. This might be undesirable since the highbass absorber only works to about 300hz.
Your heavy duty mid/high absorber should work fine. To get slighly more sub 500hz absorption you could change the gap to 2".
