Hi everyone, In my new house I will be building a new HT room in the basement. I have an HSU vtf3 and I love base. It will be a smaller size, 13x17 or so. I am a new DIY so I have done some reading which of course confused me even more. Option 1: 2x4 sleeper subfloor. carpeted Option 2: Subfloor panels, carpeted: http://www.diynetwork.com/diy/hi_ba...3891160,00.html Option 3: 2x4 subfloor stage with the sub on the stage and the rest of the room carpet over concrete. I imagine option 1 will be the best for base and feeling that vibration? Someone told me about a sand filled stage under the sub but I dont understand how that works. I posted on another forum and got confused about why you would not want vibration from the sub since some of the responses indicated anti vibration. Any help guys?
