    I have the above speaker pack, and my problem is the surrounds. The front sound stage seems fine but the surrounds don't seem to give good stereo imaging. Is it down to placement?
    Unfortunately my kit is in the living room not a dedicated cinema room, and the tv resides in the corner, which I know is not ideal. The surrounds are placed on the side walls high up about 2'6" above seeting position, about half way down the room.(Room size is 16' x 13') My normal seating position is right under one of the surrounds. Being that they are dipoles, and should reside on the side walls, should I move the surrounds further towards the back of the room, or even put them on the back wall?

    Any ideas appreciated

    Regards

    Paul

    Paul I would say that your best bet is to just try them in various postions with a sections of disks and go with personal taste. also do have the surrounds set up correctly on your amp. i.e size, distance and db level.

    hope this of help.

    I'm not sure what you mean by stereo imaging on the rears as whilst DD and DTS stuff has stereo rears as part of the spec it is not often in a film that traditional stereo is used as the rears are mainly for effects and to broaden the soundstage.

    You might get a better sound effect if you were to move them further away from the listening position but it isn't always practical to try them out in different positions before settling on the final resting place.

    I presume you have the M7ds

    I have mine about 2mtrs up the side wall at the back of the room

    Using my SR5200 to drive them I find the quality to be fantastic

    Chapter 2 of Gladiator with the arrows flying through the air is particularly good

    what cables are you using, your not using bell wire are you ?

    Ian your dead right, sorry bad termanology, I meant exactly what you said, I just felt that there was a lack of effects, but as HC is new to me and I've only just set the system up maybe I need to live with it for a while untill I've seen and heared a few more films.

    Paul,

    Many people expect to hear sound coming from the rears all of the time but there are many films where they stay quiet throughout.

    Try the opening scene from Apocalypse Now with the helicopters flying round the room in a circle.

    It is not a scientific way of setting up speakers but it sounds good just the same.

    Ian thanks for your suggestions.

    Mansell

    Using QED Original for fronts and center, and QED Micro for the rears. Maybe I need to move mine back nearer the rear of the room like you have yours?

    Regards

    Paul

    Paul,

    I can't visualise your room and your seating position in relation to the speakers.

    Any chanvce of a pic or line diagram to illustrate.

    Being dipoles they will diffuse the sound more as well. If you´ve not had dipoles before it can take a while to get used to them.

    Ideally you would have the null (the centre of the speaker as you look at it) pointing at the listening position so the drivers are firing forward and backwards.

    Dipoles should be placed at the side of your main listening position and some 2ft or so above head height. sometimes this isnt possible so make sure, as mentioned above, that the null is facing you.

    Paul,

    Thanks for emailing me your room plan. There is a problem with your room layout as obviously the architect never had home cinema in mind.

    You left speaker seems to close to the TV whilst your right speaker is too far away. I dosn't suppose that you can do much about this unless you rip out the fireplace. I have exactly the same problem and have my speakers set up the same way as you do.

    The surrounds are in the wrong place with the right surround to the left of the seating position and the left surround opposite.

    Would it be possible to move the surround that is currently on the other side of the room to the right of the settee and perhaps move left and right rears a little further away.
