    I've been led to believe that floor facing subs are better than the "normal" sub ... facing into the room...

    so I've been looking at these:

    MJ-Acoustics Reference 100 £350
    http://www.hifistore.co.uk/product.php?qsProd=REF100

    or

    Yamaha YSTSW015 £130.
    http://www.hifistore.co.uk/product.php?qsProd=YSTSW015
    Both are downward facing subs, so you get more even bass sound & feel throughout the room, and not directed at one part of the room if it were upright type.



    Opinions/reviews on the above, and are there any others that I should be looking at please?

    You have been misled then as downward firing subwoofers are no better than front firing subs or vice versa.

    If your budget is £350 I would disregard the Yamaha straight away as it isn't in the same league. I would suggest that you have a look at the offerings from BK Electronics and perhaps have a read of the sticky at the top of the subwoofer forum for more information.

    There are good and bad examples of both designs.

    But the biggest factor is your room.
    In some rooms, down firing subwoofers can't perform to their potential and can be troublesome to set up right.
    If you assumed that a down firing sub will always be better, you could be making a terrible mistake.

    I actually think that forward firing subs offer a more predictable performance in any room and a well designed one may be better.

    That said, I now own an SVS PC Ultra which is a downward firing monster and like others... I'm very happy with it.

    I saw MJ Acoustics at the recent Hi-Fi Show ...and I liked it. However brief.
    Haven't seen many others though, so can't strongly compare.

    I need a sub that is small in size....... for placing in my lounge.

    I've read about SVS PC Ultra .. but it seems too large at 39" tall!
    I want / need to hide it away in a corner ... but will still be seen.

    please advise

    I'd say its pretty impossible to 'hide' an SVS PC Ultra.
    And in actual fact, the overall hight to the top of the grill is a little over 40".

    They're big, but some people prefer their smaller footprint to that of a typical box sub.
    I've also been finding places to put mine that would not have possible with my old box sub.

    I'm not going to let this put me off my intended SVS purchase, but if there is no benefit either way, what's the difference?

    For example..... What influences a manufacturer to make a downward firing sub over one that shoots forward?.... oo..er..

    Perhaps downward firing subs are more suitable for certain applications (e.g. small or large rooms, or those with lots/minimal furnishings, or those with carpets/hard floors)?

    What I mean is.... surely, firing a whole lot of sound waves at the floor will impart different characteristics to the overall sound than firing them forwards... no?

    As a very happy SVS owner the last thing that I would try and do is to put anyone off one. It is all down to the whole design package and no sub will be better than another purely because one fires downwards whilst the next fires forwards. SVS are brilliant downward firing subs whilst B&W make equally brilliant forward firing subs

    Most subs are only producing frequencies below 80Hz on AV. With the roll-off point even lower on music.

    With the very long sound waves involved. They don't know whether they are being fired horizontally along the floor. Or vertically downwards.

    It is certainly not something that should be consciously used as a factor in choice. Unless you have nasty kids that might poke holes in an expensive driver with something even more nasty. :mad:

    The downward firing subs are much safer from this point of view unless you have mice. :blush:

    The SVS cylinders are a potential cat scratching post. But the cat(s) quickly learn that the subwoofer is a large terrifying object if you give the sub a bit of welly whenever the cat goes near it. Cats either like scratching the furniture or they don't. Some are downright evil and some are just pussy cats. :D

    Cloth grills are either a magnet for kids and cats or ignored. :)

    All these factors are more important than how the driver position affects performance.

    You guys are in the know ... ;)
    so can you please let me know which "small-ish" subs are good performers.
    At around a foot squared (30cm all round) is ideal... but will defo consider others!

    Thank you.

    Dont forget one inportant matter when deciding on a subwoofer. Small subs are designed to work in small rooms larger subs are designed to work in larger rooms. The REL Quake will work quite well for a small subwoofer if the room is around 4m x 4m and the speakers are not to large.

    A sub should not have a presentation that you hear but more of a feel, if the sub can articulate itself well in its environment then good show, but the environment is the more important part of the puzzle.

    I have always disagreed with Subs being reviewed in magazines for this reason. If the room used is either to large or to small then the wrong conclusions are to be had.

    I would always advise that you speak to your local dealer regarding what would be suitable for your room and system.

    Hello IamA,

    I agree with most of what you say except for the part about magazines reviewing subwoofers as they should always qualify their reviews in any event

    The room would be fairly small...
    it's L-shaped ... with the narrower end being used for dining.
    The rest, in a virtual square shape .... very close to 4m x 4m !!
    (with dining area, 4m x 7m)

    I would go for the XLS200. The original RRP can be misleading as the XLS 200 has never been sold in any other way but directly to the public by the manufacturer. If it was sold via traditional retail outlets it would probably be priced at £500 plus.

    Quite a few forum members have already bought one and they all seem to be very happy with their purchase

    for the XLS200 it states - Frequency Response at -6dB: 17Hz
    assuming that this means it can go down to 17Hz....???

    that is low....!

    Answered my own question!!
    Its a grille. Full spec is here:
    http://www.bkelec.com/New/Special_Offers/sp5.htm

    From the UK, so no excuse for me not to get one!!

    1 other question though ... how would u know what to postion all the dials on the back on? Is it just a case of playing around with it until it sounds ok?
    or there must be a set "optimum" for quality?
