    I just recieved my Q150.

    Its going to go in the corner of the room, so I need to decide which way to point it.

    Shoud I go with:

    1. The driver pointing into the wall, leaving the controls easily accessible

    2. The driver pointing into the room.

    I guess that option 2 would be the best sonically, but like this would make it near impossible to adjust the controls after installation.


    Any info would be appreciated

    I am also interested in this - I recently bought a M&K V125 (which I think is superb) I have mine facing the wall about 1/2 foot away from the corner of the room, as it says in the manual.

    However I always read conflicting reports about where is best.

    I haven't experimented yet (but I will) as I think that this works well

    How do most people have theirs set up?

    You will have to try several ways until you find the sound you like most, more bass or tighter...

    I was even thinking of putting it diagonally (I think I have enough) so that the sub fired into the corner, instead of a wall.

    I guess that it will need a lot of playing, as I could point it in to 2 different walls.. One is an external (dry lined) wall.. The other is an internal plasterboard partition.

    The problem I have is the space needed to turn the sub around.. Its behing a big glass rack, with a huge TV on top.. Its going to be difficult enough getting it in, let alone turning it around

    Hmmm......

    Not sure about firing it at the plaster board partitioned wall.

    I think it just takes a lot of experimenting with different source sounds.

    Firing into the wall or corner produces greater rumble, slightly higher decibels and percieved lower/deeper bass (keyword here is percieved) .

    Firing into the room gives you a cleaner, faster, tighter bass responce every time. I prefer the latter way. Music also sounds a hell of a lot better in this position.

    M&K do actually recomend pointing the driver towards the wall and having had several demo,s and my own subs, this does work, and doesn,t !!!
    Once your sub is correctly set up , and if this means that the controls are out of reach, surely that would not matter, as once it is set up , you do not need to play with it any more !!

    This is something you really do need to experiment with , and make sure you try all your options. I have posted a reply to a previous thread on this, but i can help more if you like !!

    Personally i have a M&K set up ( yes stunning !! )

    Kev,
    Asides from M&K many other manufacturers advise firing off a wall or corner. . Placing the sub or subs (more than one is better) in these positions leads to them actually producing a more independent bass respnse. This then leads to the problems I mentioned previously, ie, a muddy, boomy bass that stands out from your main speakers like a sore thumb.
    Over the last few years hometheater acoustics have been looked at in great detail. Many now believe that firing INTO the room is the way to go. Exhaustive measurements and calculations have shown this to be the most accurate way to acheive the smoothest bass response.
    A subwoofer should be used to extend the bass response of your main speakers and blend in seamlessly. Try both methods and see for yourself.

    I have a two year old and if I faced my sub into the room the cone would be broken inside the day.

    Shame they don't fit grills to the cone, at least it would afford some protection.

    Ian,
    An 'Acousticaly Transparent Fireplaceguard should do the trick;)

    Seriously, I know its tough with small kids. I ended up buying an electric tentioned screen costing 3 times as much as a fixed screen because my four year old thinks she is Picasso when she gets hold of a black felt tip pen.

    When I built a sub in a box for my car, (when I was a boy), I bought a metal grill which was designed to fit over the sub.

    If you really wanted to point the sub into the room, but wanted to protects it from children, you could quite easily fit one of these.

    It would mean screwing into the box, which is a shame, but it would protect the speaker, and I doubt if it would have any negative acoustic effect.

    Jon,

    I showed your thread to my wife which she found highly amusing as she has had the dubious benefit of seeing my DIY skills.

    As she will tell you, the only thing that I can make is a mess.

    Seriously though, I had my Q Bass facing the wall before junior was born and am quite happy with the sound. I don't know how big the current models are but my original is a big ugly fella and facing the wall can at least pass muster as a coffe table.

    :)

    I must admit that waving a screw driver around infront of an expensive speaker can make even the most competant DIYer nervous.

    When I used to screw the driver into the box, I used to s**t myself..

    One slip and it would all be over.. It was especially difficult with large speakers as there is normally a large magnetic field, trying to attract all metal objects into the cone.

    Now I come to think of it.. Its best leaving the Sub alone and get rid of the kids instead.

    Move the sub to face the room and make the lids face the wall!

    I just found a small section in the manual which states "The Q range are deigned to face towards the listener"

    Looks like I had better move it around and see how it goes.

    Jon,
    One day all Subs will point that way.
