    It has been chewed here and there, but not all things are clear for me.

    I have a 4 speakers system (Ref 40s, Ref20s) - they all from the same line and sounds pretty close. The center channel is just a phantom. So what can I tweak here? I've set up timing delays according to the distance and set up left channel to +1dB (different walls) to be even with the right one.

    I don't see what else I can theoretically play with.(H/K 520).

    My 15" sub is almost done, so it probably will be more interesting. But except for the tweaking the phase, so it blends with the mains and lowering the volume, so it doesn't get all attention to itself, what else can be done? (my room is quite small, only one or two places to put sub in)

    The biggest "tweaking" issue is to get all 6 speaker even in level (or in your current case, all 4). No single issue in the audio system has bigger impact on listening enjoyment, IMHO.

    The only way to get everything actually even is with a test tone disc and a meter- you'd be hard pressed to do it by ear. This you use the DB settings for each speaker to get them even in output sound pressure level.

    Usually the next step dabblers in the hobby take on is EQ'ing their subwoofer (usually using a Feedback Destroyer). You can do a search on "BFD" or "House Curve" in the speaker/sub section of this forum for more info.

    Note: we have a "Tweeks/Connections" fourm that might give you some more ideas. There is a current thread about peoples favorite "tweeks" that might interest you. Pop over and give a look.
