DIY Panels Insulation materials - what are the differences

[kermit_xc]

howdy there, I went to HomeDepot and picked up a pack of Fire and Sound Guard Mineral Wool by Corning to make bunch of acoustic panels - I know Corning 703 / 705 seem to be go to choice for insulation material in acoustic panels





The density is 2.5 lbs/ft^3 - comparable to Corning 703 ??? now that I have them setup at first reflection points ... I think it sounds great - but I honestly can't tell a huge difference, nigh and day? no!

I picked it up because it was $30/10 panels + $15 for 1"x3.5"x8' wood.

Will there be any major difference if I go with one of the expensive options? is density the only spec to go after?

my room layout for reference:

I would flip sofa position with your setup...

yeah - I turned the room around - definitely more room and symmetry to build proper bass traps - but now I have a window at the first reflection point
Speaking of bass traps - do they need to go floor to ceiling to be effective?
