[QUOTE="Vaughan, post: 207791, member: 693"] It's a wood panel trap or pressure trap. :) Must be mounted directly to the wall, unlike porous absorbers, which work based on velocity, hence their name velocity trap. I think what Ethan meant (concerning the use of these pressure traps in larger rooms) is that large rooms have proportionately more flat surface area versus corners than small rooms, so it would make more sense to use these traps there given the size of them. So to answer your question "porous for small rooms, membrane for bigger", I would use porous (including a membrane for enhanced LF absorption, scattering of highs), rather than just wood panel traps. Your panel absorbers look great. :thumbs: [/QUOTE]
