The BALMORA is a high-performance, 3-way, floor-standing speaker with its woofer in a mass-loaded transmission line (ML-TL) that can be built for a moderate cost. Second, stuffing material is not really important. The transmission line, or TL, is also known as an acoustic labyrinth because of the long and somewhat complicated path that the rear radiation of the speaker must pass through before exiting the enclosure. 5" No stuffing will be used The corners will be rounded more than pictured to fit the line length better The walls will be 0. I just couldn't get a TL sub to work. audioXpress.
