Thanks guys, yeah i was planning on using 2 (placing them next to the left and right and pointing toward the center) due to the design of the room, thus the screen size is too big, making it harder for me to place it in the center. unless i place them flat on the floor or mount them on top of the ceiling.
The 2 spare speakers that i have isn't match with the one i currently have for left and right. But if you guys dont recommend 2 speakers for main, i will have to look into trying to place one in the middle then. Here is the picture, As u can see the height of the screen is reach top to bottom leaving 6 inches from each sizes. There are movie where i can use 2:35:1 mode which make it long and narrower but there are some movie that would go full screen.
If i was to place the speaker in the center it would have the dimension height of less than 6 inches and i dont even if it will sound good laying on the floor like that. I'm using 2 speaker now for the front, it seemed fine to me but then again i'm not so good in the sound department to notice differences.
any recommend speaker for my center, (i'm using Onkyo sr800 and my left and right speaker are DCM) maybe i will just use one of the spare. My question is, what is the different between the built for speaker to use in the center and the built for speakers to use for left and right?
Thanks again for the advices
