Hello... just wanted to get opinion on what type and where to place
speakers in my house..

I'm planning on setting up a room for music audio.. the room size is
8.5 x 18 the layout is this..

front wall

I'm not familiar with audio/stereo system.. so I'm not 100% sure what
type of speakers I can use..

I'm just wondering since it's a long narrow room (will be a dining rm),
should I...

1) place In-wall speakers in the back wall (8.5 ft length)

or

2) place 2 x in-ceiling speakers instead that is 6" apart from the
centre of the room (ceiling is 18 ft long)?

Also, I read that there are single speakers that can play stereo (play
both L and R) - is it better to place two of these speakers in-ceiling
or should I place regular stereo speakers (one L and one R speaker)


Also, with stereo input speakers - do they have to have 2 tweaters and
2 voice coils to be stereo input speakers? Or any 2-way speaker IS a
stereo input speaker?


I know these are pretty basic questions.. thanks for your time and help.
