Will applying resin on the inside of the box kill any sound or sound waves? Im going to apply resin on the side to further strengthen the box.

I've heard arguements on this both ways.

My personal experiences' however have given me nothing but positive results. I say go for it

Just try to realize you will lose airspace, whether it's a significant amount or menial is all up to you and the amount of layers you apply

i'm sure it's dependent on each persons individual situation on the gains u would see...chances are it won't be noticable to the ear...just the mic.

prolly won't make the box louder...just makes it stronger... go for it... can't hurt

Doesnt make it stronger either......as paint doesnt make the inside of a house stronger

hes right, resin wont add strength. resin alone has no reinforcement, thats why mat is used..

fiberglass matte hellps i have seen guys gain some serious dbs by doing it. an some lose some dbs but if your going for mic numbers first build your box test to see if it putting up good numbers then resin it. but just for sound i would recommend some bracing and a good box build prolly double baffling it wouldn't hurt either
but if you resin it use a rubber roller an dont mix your resin hot cause you want to take your time doing this

Resin applied to the inside of the box, doesnt add strength worth noting. Actually, adding mat and resin over large flat areas does not do much for strength either. If you are looking to make the box stronger, like said above look into other types of bracing.

putting runs of rope or wire underneath glass for long straights works excellent.. very strong reinforcement. i dont know about doing that on the inside of a box though...

Very true.

With the cost vs. performance ratio, I would go with other options personally.

Not harder. It's hard to distinguish...
But the DENSER the enclosure is, the more response you'll get.

The reason people put resin inside a box is to seal the MDF not to make it stronger. MDF alone is porous.

i have seen it make my boxes peakier. it can gain it times, and in times it wont. generally for spl, people say to resin. it also can raise your reactive load. the most gains i have found is mixing saw dust/sand into the resin and then applying. if you want it for purely strength then just do some threaded rods.

This is why i did it...especially in the corners. However, if I could cut worth a lick, I wouldn't need to that anyway. It's a bandaid for lack of craftsmanship.

It had a substantial gain in our application (Mach 5 + sundown build)
