    Hi there,

    After listening several brands of speakers in some local dealers I'm in the process of buying a Polk audio system for music listening and home theater system.

    The system would include the following:
    Front: Monitor 60 / 70 (depending on budget and wife approval ;) )
    Center: CS1
    Subwoofer: PSW10
    Surround: FXi3 (bipolar mode)

    The room is 5,35m x 4,15m and here you may find a floor plan of the room with expected location of speakers:


    -----------CC-----------------
    |·····F··TTTTTT··F·#S········| D, W - Door and windows
    W····························D # - Columns
    W····························D TT - Television (Sony 41SP retroprojection)
    W····························| CC - Center (wall mounted ~1,5m high)
    W····························| F - Front (~2m separation, on a 0,35m high platform)
    W····························| R - Rear
    |····························| S - Subwoofer
    |······LLLLLLLLLL··R·········| L - Listening position (sofa)
    |···R··············#·········|
    ------WWWWWWWWWWWW------------


    I have several doubts:
    1. Is this system overkill for this room? I'm afraid I'm expending too much money in something I wouldn't be able to fully seize

    2. If you take a look at the layout of the room, it's impossible to locate the rear speakers lined up, as I have no wall space between the rear window and the column. Would a bipolar system suffer from such a layout? I understand that part of the effect of such a surrond speaker is obtained thanks to reflections in the wall they're mounted. Should I lose this effect if I mount one of them in a column with little reflecting surface? (The columns are 0,45m wide x 0,25m depth)

    3. Is there any problem locating the center speaker that high (around 1,5m)?

    Thanks a lot in advance, best regards
    Jose

    im no expert on placement but have picked things up about it in my time, the centre should be fine, you should point it down towards your head if necessary though.

    I have bipolars on a back wall about 1m behind me and i fear i lose some of the effect, as im not sure the drivers pointing away from me have much effect, but thats the way it is.

    what about this: it should work better and if possible, its where bipolars are meant to go AFAIK.

    And then you could move the front lot to fit, although not necessary

    Or alternatively if you have a suspended ceiling, get some in-ceiling speakers. There are some bi/di-polar in-ceiling speakers from Atlantic Technology which are good, alternatively use monopolar such as KEFs (the KEFCi200.2QT even slide out automatically and point directly to the listening position). Laying the cables through a suspended ceiling is pretty easy and if you go for in-ceiling you could even get a 7.1 setup.
