In this third step I show you how to damp the walls and add the stuffing and finally glue the last side onto one of our Frugal Horn XL full range DIY speaker kits.
Stefan, Very Informative. Thanks! Quick question: You use stuffing down the whole horn line. I am building a small TQWT tower speaker and their build plans only use polyfill down one chamber and is ported out the front. I know this design is not exactly a horn but would you use stuffing down the entire TL in a TQWT tower?
