Product Description
NeoFill-HD is used for technical sound absorption. Its industry leading 150-200 PPI open-cell surface with activated carbon granules guarantees that sound waves are not reflected as an echo but can penetrate the cell structure unhindered. The sound energy is reduced in the cell structure, giving NeoFill-HD an excellent sound absorption capacity. NeoFill-HD excels at absorbing a wide range of frequencies due to its high density which has been formulated to improve low frequency absorption below 300Hz.
Granular activated carbon (GAC) has numerous applications due to its ability to adsorb and desorb air and gas molecules. It has been shown to exhibit unusually high low frequency sound absorption. This behavior is determined by both the multi-scale nature of the material, i.e., the existence of three scales of heterogeneities, and physical processes specific to micro- and nanometer-size pores, i.e., rarefaction and absorption effects.

I’ve put the panels up directly – no frame or fabric needed. The panels were so heavy I was worried if the pins will hold them, but the Propins are holding up fine so far. Some fine black powder initially fell from this during installation, but the company explained that this is due to the large amount of activated carbon in the panels. The performance is truly amazing.

Past 2 years i am into hifi hobby. Spent lot money went several upgrades . Always I felt something not right. I saw lot of videos about advantages of acoustic room treatment but never tried because they do not look good in my living room. Finally just tried to improve room sound rather than swapping components. With the neofill panels there is more weight to vocals, mids are clear and even highs got their body. music is no more busy. Big improvement is image become centre and more separation from left and right. This is may be due echo reduced from back walls. I am totally using 8 panels covered with fabric.
