    Why the questionmark...well I am not sure if it's a real rpoblem. Maybe more of a problem with placement.

    Anyway I notice that in a certain portion of my room the subwoofer is much more noticeble, than from my listening position.The sub was shaking that small part of the room.

    How can this happen? Could someone explain this to me?
    I have calibrated the sub from my listening position.

    All subwoofers will react with the room and produce a different sound in different parts of the room, to put it simply. There are quite a few technical explanations in other threads within this forum as the reaction between subwoofer and room is one that is discussed frequently.

    The recommended method of finding the best place to site your subwoofer is to place it at the listening position and walk round the room until the bass sounds the tightest and that is where the sub should be positioned. Problem is that the best place is freqently where you don't want to put it anyway.

    That's true.
    Frankly I only have two spots where I can put up the SVS.

    What do you mean with tightest? Does it mean loudest or most noticeble?

    its just a function of your room im afraid...... dependent on the exact environment, you can get constructive or destructive interference making the sub seem loud or quie at certain frequences. Of course constructive isnt good, so you may have better response from your sitting location despite it being more obvious elsewhere. You should do a analysis with test tones and spl in both locations to see which gives a smooter response. Then you need a BFD to correct any inconsistency.

    not loudest or most noticeable..... it is very very hard to do without either an experienced ear or an spl

    I had a party last night and finished up sat on a deck chair in the corner of the room, next to my normal listening sofa.
    Well it struck me that the bass in that corner was better than anywhere else I'd listened from before.
    Not that several cans of Stella affected my judgement!:zonked:
    Anyway i was inspired to find the svs a new spot, but unfortunately I think it's in the most practical location for my room.:(

    I don't imagine SVS cylinders looking or performing quite the same on it's side.

    There has been discussion of sv subs on their sides, but if i link you to it, the post will be deleted. So if you want to know where to go to read about sv subs horizontally, pm me and i will tell you.

    err - not sure why the subject of these subs on their side should be taboo, especially as the SVS website says "They can fit in very tight home theater corners, or even lay down behind a couch" - see http://www.svsubwoofers.com/subwoofers.htm.

    (unless that was an in joke and I am very thick!)

    edit - can't get the direct link to work.

    at least one person has reported that the side orientation is not as good as upright.
