It may be too late for me now as I've already had one built. But it would be great to list down all the things that need to build a perfect HT room as reference for others  1) Avoid plaster ceiling / Enhanced support for plaster ceiling if really want to go for it: One thing that I regret most on my HT room is having plaster ceiling that it will rattle during extremely strong bass and some powder or white stuff will sprinkle on 2 corners. 2) Decide if the equipment will be on side or front: My room is a bit narrow with all three recliners site by site. Giving me a 2nd chance, I would probably but my equipment rack in front instead of side. 3) 4) 5) Please add on the list like golden ratio of the room (LxWxH) etc |

To fix the problem on rattle plaster ceiling, you can get some sound absortion foam and stick on the place you feel the rattle. This will greatly reduce the rattle

This not only for the corners. You also will need to put it on the flat plaster ceiling. Of course those with skirting on the corners you cannot do anything about it. The rattle mostly are on the flat board of the plaster ceiling. You concentrate on it and it will reduce a lot of those rattling noise.

Wah...........Auralex is very expensive. I got mine from a guy who selling acoustic foam in hifi4sale. 1 piece of 50cm x 50cm is RM22, I bought like 5 pieces to stick it on my plaster ceiling which I know got rattling sound. After doing that, the sound had reduce a lot but sometimes those LFE still manage to rattles it but is much better than before. Infact my TV back panel also rattles when there are a lot of LFE. I also had to put those foam behind my TV. Planning to get some diffuser to put behind the front speaker as well later this month.

geforce, putting fiber glass on top of the plaster ceiling will help to reduce the vibration. It will tidier since it is inside.

There are a lot of form in the market that I'm not sure if they really help, thus I only approach those famous in the market... |

If you have access to the top of your plaster ceiling then you can put fiber glass on the plaster ceiling to weight it down or anything that have similar weight will do. Even putting a book is ok. Unfortunately, for my case the plaster ceiling is fully sealed so I can only do anything from outside. I used 5cm thickness foam, it does pretty good so far. Never try bass trap before, but I believe most bass traps are for corner only. Advice me if this not correct.

Without the wooden frame, i think they are quite light in weight... i have the same dilemma before,what i did is just tear down all the plaster ceiling,install a wooden frame,put one layer of fiber glass and use gypsum board as a ceiling(u also can use plaster ceiling )..problem solved. |

That'll be my 2nd last solution if everything else does not work. A bit of extreme but really irritating hearing those rattling sound and seeing those white stuff at the corner and my equipment after turning on the light  Let me try some bass trap first then... |
