Volum reduction or sub across the couch, sorry but it is not an option.
I begin to understand how to build the room, i will describe it when I'm back from vacation, traveling tomorrow.

You cannot turn down the volume?


It's your hearing your talking about losing...not if, but when.

Appreciate your concern Space, but the volum is not that loud.

Hi Ted.
How much difference will 7 cm represent if I lower the floor, the room is 730x330x223 cm.

Are you suggesting removing the concrete floor and re-pouring? I'm confused... sorry.

7cm isn't a lot of height to gain considering the work involved. Again, I'm probably misunderstanding

Sorry Ted, but I have problems to explain me properly, will try to be clearer.
I`m not removing the concrete floor and no re-pouring. The height between the concrete floor and roof beams are 230 cm. Between this I will build floating ceiling and floor, and the space is limited.

Well ceiling height is always a desired thing. So I would see if you could avoid losing the 7cm

Very interesting points on mass and isolated walls to absorb low bass... Out of curiosity, what *would* be an effective air gap/wall mass to absorb <45Hz? Are we talking 3x or 4x 5/8th drywall? something heavier??
