Density about fiberglass panels
I started the thread "Building some bass traps, check 'em out ", but since this is an specific question, I must create a new thread . Hopefully Ethan or Glenn could help me out here.
My problem is the following:
I bought low density fiberglass panels, without knowing they were 18kg/m3 (like 1.4 pcf)
I already put those panels inside 3 frames (out of six) but even tho, i'm gonna make a few calls asking if i can find more denser panels here in Chile, i dont mind taking them out if they totally wont work.
I was seeing some absorption charts, and the diference from 18kg/m3 to 60kg/m3 is not that radical, it only improvees a few . The numbers only raise up a lot from panels of 90-100kg/m3 and above
Can I still use them? Or I better buy the denser panels i can find here?
Obviosly i know the answer. The denser the better. BUT, Can I still use the 3 panels i already made for the sidewalls and get thicker fiberglass for bass trapping? (So i dont completely lose the money i put on the fiberglass panels i bought)
PD: The panels i bought are 2" thick 18kg/m3. So the idea is to buy 2" thick as well , but denser
