i am nearing completion of my ported sonosub and have one question. is it a must to put some type of dampening or foam on the inside of the sonosub? what exactly is the gain from doing this? and can i get away without it? thanks for any help. also would the typical yellowish egg carton foam do anything?

Line the interior surface with a layer of R-13 fiberglass insulation.
Is it a 'must', yes IMO it is, since I've never heard a sub where the performance wasn't improved with the addition of this damping.
And believe me I've heard a lot of DIY subs....

You can peel the r-13 into layers and line the tube. Its a little to thick to use just by itself. I used spray adheseve to attach the lining.Comment

You have to put a fair amount of it in before it starts having a significant impact on the tuning.Originally posted by darren700ok thanks for your help also would it affect the tuning in any way? i beleive i recall stuffing a box tricks the woofer into thinking its abigger box?

They are home insulation foam.

OK. I know that the best option would be to buy Acoustic Panels from a manufacturer such as Real Traps. Or if DIY, then using Corning 703 insulation.
But who knows if I would ever get around to either one of these options. So, since my basement was recently finished, including... -
As I am finishing up my boxes for my big Statements and 2RCC build the question begs which way to go, foam or insulation? I have read through all of the posts and have been unable to find any definitive answer, foam or insulation? I do know some were concerned about the health issues of insulation.... -
