PeteSiebenand Posted August 7, 2011 Report Posted August 7, 2011 probly been asked before but i thought id ask again i have a non ported MDF box and ive heard on the grape vine that MDF is porus, ergo letting out sound. ive had a little idea to use some sound deadner like dynamat on the inside of the inside of my box, BUT i want to paint the inside first with some acrylic paint to deaden it further. good idea or not? what should i put on the inside of the box? i want the best sound quality. also i have purchased a hifonics zues sub, opinions? cheers in advance Pete
BJD3 Posted August 7, 2011 Report Posted August 7, 2011 I can tell you without a doubt in my mind. You'll have problems with the box flexing WAY before you have an issue with MDF leaking sound because its porous. Anti Peel and Seal...lol You may be offended by the above.

TRTC360 Posted August 7, 2011 Report Posted August 7, 2011 deadener isn't made for what you're trying to do, try some polyfill inside the box, it should help.

kirill007 Posted August 7, 2011 Report Posted August 7, 2011 you can use fibeglass on the inside and make sure you brace it well. Maybe even a bit of polyfill, but shrink the enclosure about 10-15percent. But deadener has no use inside a enclosure. Its made to deaden thin steel. And if you want the best sound quality, why buy hifonics? :s Thinking is the root of all problems... You ALWAYS get what you pay for.

You'll have problems with the box flexing WAY before you have an issue with MDF leaking sound because its porous. surely it will help tho? Would it help? Maybe. Would it be audible enough to justify the cost of deadener? Likely not. However, like most things audio, there aren't very many hard and fast rules. Try it and find out. But the difference wouldn't come from MDF being porous. Anti Peel and Seal...lol You may be offended by the above.
