My movie area is in my family room in the basement. Its pretty much half of the basement with my area on one end and the wife controls the other half lol. We had a mold issue due to the basement walls being built touching the foundation which resulted in our insulation getting wet and developing mold. Had to gut all the exterior walls. Bummer, but Im adding a atmos system now. The last thing I need to upgrade is my subwoofer. The room is 43x13 with a 8ft ceiling. I have about $1,900 budget. It will be for movie's only. Im just not sure which way I should go. This will be a one time deal, I will not be able to add a second sub later unless my wife divorces me lol. Here is the list I'm looking at right now. Im just torn and which way would be best to go.\n\nRythmik FV18 Paper cone $1,799\nHSU 15H-MK2 Dual Drive $1,749\nDayton Audio 18" Ultimax Kits (2) $1,800 I don't mind building them.\nParadigm Defiance X-15 $1,499 ( my only local option )\nMonoprice THX 15 $1,338\n\nMy gear is as follows\nDenon AVR-X4300H \nNHT ST-4's fronts\nNHT SC-2 Center\nNHT HDP-2 Surronds\nMonoprice 8" in ceiling for atmos\nCurrent Sub is a NHT U1 set up.
