Room Acoustics and Speaker interaction.


I would like to have a secondary system in my small den which is only 11.5ft by 11.5ft with only a 7.5ft ceiling. Very small and very square...yikes!

So, because the room is so small, the speakers need to be close to the wall that resides behind them.

So this got me thinking about speaker types: sealed/front ported/rear ported, etc as I want to avoid a booming bass. But then I was thinking.....is it really the ports that are problematic or is it just certain low frequencies that are reacting to the room modes? Any thoughts?

How does one determine what frequencies to watch out for in your particular room?

Unfortunatly, I will only be able to have about 12 inches behind the speakers. Thank you Bob for sharing your links with me.
Why not mark a spot out from the wall with tape. When you decide to do serious listening move them out towards the marked floor?
Hi Schipo,

I understand what you are saying......but, here is my wife's answer to your suggestion:

"My husband already has a dedicated listening room which houses his "reference" system in. He is free to do as he likes in "that" room and is welcome to do his "serious listening" in there anytime he would like. As to "my" den, he is welcome to have a nice set of speakers in here as long as they fit into my decor and are unobtrusive.....which means they will NOT be pulled out into the room. This room is small enough as it is....I do not want to be tripping over his speakers besides."

So there you have it. I have a few obstacles I am dealing with......a very small room, one that is square no less, and my wife.......(just kidding, honey!)
No_regrets, why would you want to put speakers in her room? Would you like if she was putting things she likes (e.g. shoes) in your dedicated room? :)
