Acoustic Panel Differences

I had someone drop off some samples I can test in my HT of these EzoBord panels:
https://www.ezobord.com/prod/panels/

I'm wondering how they compare to these 242 panels from GIK Acoustics:
https://www.gikacoustics.com/product...coustic-panel/

I wanted to run some REW measurements of my HT room without any panels and then since I have the EzoBord samples I'd try to see if they do anything to help on my first reflection points but I'm wondering if I should even bother with the samples since they are not very thick compared to the GIK 242 ones or even full bass traps from GIK (the 244s).

By REW measurements gated ETC charts right?



Why use such thin panels and band-pass your sound?
Sure - for office environment those EzoBord help tame office noise speech etc , but for HT you need much lower freq than those.
Size / depth does matter ...

Don't bother with the ezoBord panels. They absorb in the upper midrange and treble only.

I have three of the GIK 242s. They are effective from the midrange up. They should be combined with bass traps in the corners, with some kind of membrane to limit their absorption to the bass only.

Since you can measure with REW, your objective should be to keep the RT60 vs. frequency curve relatively flat from ~200 Hz on up as you add acoustic treatments. An imbalanced RT60 will color the sound. If you can't measure RT60, then just choose treatments such that when you add them together, you get roughly the same number of sabins in all frequency ranges.

HT: Dynaudio C2, Contour S CX, 2x BM14S, Aperion surrounds, Simaudio Titan, Marantz AV8801, Oppo 103, Linn Majik DS, and a Pioneer Kuro
Stereo: Dynaudio Focus 160, Simaudio W-5 LE or Luxman M-600A, Linn Akurate DSM, 2x Rythmik F12G
Other interests: motorcycling, skiing, being active
