I have been building speakers and subwoofers for many years. Combined total well over 100 enclosures easily. For sealed boxes I always use the standard "fluffed" polyfill from Wal-Mart or other craft stores. For ported boxes I have always used egg-crate foam or polyfill batting glued to the inside walls. As mentioned, of the many speakers I have built, I have never had a problem nor a complaint about either. Cheap, easy, and it works.
