    Ok all having now been the proud owner of the 909 for a week and boy does it make a great coffee table LOL from my previous sub, I am wanting to experiment with settings. Ed is sending me a cd but thought as I had some spare time I would play around so to speak!! So any suggestions as a starting point? Sub is in corner of room forward facing towards my listening position. Only other possible place I could put it is next to me by the sofa. Using auto set up on amp I have a crossover of 160mhz. Below is what me equipment contains. Any help/advice much appreciated. As yet no SPL meter so all by ear at the moment.

    Yamaha DSP-AX757SE

    Denon 1920

    Mordaunt-Short 302's fronts - set to small on amp

    Mordaunt-Short 905i centre - set to large on amp

    Crappy Panasonic satellites from old system surrounds - set to small on amp

    Mordaunt-Short 909W sub - crossover at max, volume at 9 'o' clock

    Crossover using auto setup @ 160mhz.

    Am new to all of this so any please??

    Cheers,
    Iain

    I would set the centre to small as well and I think that the crossover is much too high. Your main stereo pair are supposed to go down to either 100Hz or120Hz dependant on which website you read. I would try 120Hz but you may still find the upper bass from the subwoofer to be directional.

    If it's any help, my 902's go down to 55Hz.
    The 905C goes down to 60Hz
    My 903 rears go down to 120.

    I used to set my crossover for the 309 sub (very similar to your 909) to 100 Hz.
    80 was too much.
    I'd guess IanJ is not far off at 120.
    Definitely set the centre to small.

    Thanks Badger,

    How do you find the 903's as rears?

    Nice mate, IMO.
    I've said many times on here, that if you are used to normal bookshelf speakers, they at first seem very diffuse.
    That is, they lose all directionality. If you like "Saving Brian's privates" with the exceptional bullet sounds coming from behind, the 903's are not for you.
    The 903's, are made to give a...... what's the word??.... ambience.
    Bear in mind, THX actually recommend this type of speaker.
    I found that when setting my speakers to reference, I wasn't happy, because I got the impression they weren't doing anything at all.
    So I jacked them up to suit my ears and now I'm chuffed (probably +7Db).
    They also work with multi-channel music for me because, as they don't go as low as the fronts, they lift the whole dynamic range slightly.
    Truth is, I find the MS have a slight "hole" in the lower-mid range, so this slight lift suits me nicely.
    In short, I'd recommend them, but try to demo them first, although I know this is difficult with MS.
