Room Shape

[Fowl]

OK Guys, as I have mentioned here before my H T room is almost a square. It is 12x11x10, which is not great for sound. So since I cant change the size of the room I am thinking of changing the shape. I am tihnking of coverting the front of my room into a pentagon shape. Would that help with sound quality?

Guys please help, the guys is coming over in 2 Hrs to give me a quote and need to know if I should go ahead with it.

I don't think it would be of much of any benefit to change the shape of the room, as room modes will still be present, flutter echos along one axis will be removed though.

I think the most benefit would be had by constructing the room to improve soundproofing, it might be possible to construct resonant panel absorbers in a wall or two to help with room modes. If not, budgeting money toward room treatments would most likely do more good in a room like that than changing the shape.

That's my recommendation, there are acoustician's and other more knowledgeable ones that populate this forums that could be more helpful, should they find this thread in time.

OK guys the workman came buy and did a true measurement of the room. The dimensions are 12x11.11"x 9.11", good lord almost a square, so here are the suggestions. I can "furr" out the wall and make the dimensions 11x11 6"x9 11".

What do you guys think? Will this help. Need some advice

Room layout

Your room is too small to build a room within a room and still have space for speakers and furniture. Consider adding room treatments and experiment with the best location for the sub or possibly dual subs to reduce room nodes.

jcPanny,

Thanks for your response, but I am not building a room within a room, we are widening the walls so as to change the dimentions of the existing room. We are going to make the room 11 ft deep x 11ft 6" wide x 9ft 11" high.

So I am asking you guys if this should assist with improving the sound.

Room dimensions.

Making the room 11' x 11' is more square and may have more problems than the origional 11' x 12'. If you are interested, there are some spreadsheets with the "golden" room dimensions but if you follow this you will end up with something like 12' x 9' x 6' celing and not have enough room for speakers or people.

I think your money would be better spent on some extra acoustic pannels and better speakers then on room constructions.

jcPanny,

Thanks again for your assistance, yes I am interested it that spreadsheet. Please send it to fowl8@hotmail.com.

Perhaps I will just put a library against the wall to help break up the sound waves, and perhaps get some accoustic panels.

You can do a whole lot ...

to improve sound with speaker placement and speaker sound levels.

You might want to try that first, Just a thought!

What will help the most is setting up the system on a diagonal. If its at all possible.
Having the main speakers at or near 45* to the walls will reflect the sound differently, than if setup square.

I never though about putting the tv in the corner. After reading that article, I may try to do that in my new room, theory behind it sounds logical.

Yes, it works quite well in smaller rooms. I've setup stereo systems on a diagonal in small or odd shaped rooms. It cuts down on the early reflections you would normally get with the mains square to the room and close to the side walls.
Of coarse the best solution is to have a big room in both directions, so the seating isn't against the back wall and the main L/R speakers are at least 4~5 ft away from the side walls.
