    i have a problem with my setup, it always sounds boomy no matter what i play.
    when it plays deep bass, all i get is boomy bass, and not deep bass.

    i have played arround with the setup of my subs (both crossovers set to max, then tried setting up the crossovers to match my speakers), but i have had no luck in reproducing clean deep bass, just boomy bass.
    here is a layout of my room:

    The 603's are big floorstanders, right? If so, they may be a bit too big for your room. I wouldn't think it's very likely, but you never know. Have you tried the 601's?

    It may just be that they're too close to the back wall. I don't know how much free space the 603's need, but with a lot of speakers (particularly bass reflex ones) you need to have them 30+ cm from the rear wall to avoid bass boom.

    Alternatively, it may be due to the fact that you have two different subwoofers! I've heard that setting up even two identical subs so that they don't cancel each other out or boom horribly can be a nightmare, and with different subs it's even worse! What happens when you turn the subs off? Does the boom go away?

    Cheers,

    Dunc

    I would take the subs as the first question mark. I have heard some of the yamaha subs and they can sound a bit boomy at times.

    what are the room dimensions?

    turning off the subs seems to make no diffrence to the sound, still boomy.
    the room dimensions are 4.3M X 3.8M

    i tried to use a pink noise graphic EQ with mic to adjust the freq.
    of the sub, this has made some diffrence, it sounds slightly better.

    I can see that around the 63Hz mark the sound booms i tried removing this, which had some effect on the 'boom' of the sound, it sounded better!

    i still have some boom left tho!
    both the subs are yamaha - YST 180 + YST 800

    i could try to put the subs at each side of the main speakers, what do you think?

    the size shopuldnt be an issue if that is the case. As suggested, how far are the 603'2 from the wall?

    they are about 50cm away from the back wall.

    would putting the subs in the corner of the room make a diffrence?

    My next question was going to be, how far from the corner is your right hand 603? I would keep the subs well out of the corners as this would likely make the problem worse.

    im at a bit of a loss, the yamaha should be able to drive all the speakers easily enough, the subs you have discovered are not at fault.......maybe your room is just reinforcing lower freq due to its dimensions.

    May be stupid ;)

    You said that is boomy without the sub, so let's supose that's the problem is the 603.
    Did you try to set the speakers as small (no bass send to them) with an high crossover ?

    i have tried to set all speakers to 'small' then set 'LFE out' to 'SW'
    it sounds slightly better, but its still there!

    i have tried my setup in 3 diffrent rooms so far with the same results?

    my 603's seem to be ok, i have triet to bung the ports with the supplied foam bungs, this also helped a little, but whenthe bass goes really deep all i get is boomy and not bass! :(

    could putting both subs at the side of the left and right front help?
