    Hi I have noted that now Bk has an XLS down firing, very nice indeed
    now what my question is is there any difference in bass between the two?
    They have both the same power and construction quality

    There should be no difference in the quality or amount of bass between a front and downfirer per se. What differences there are will be down to overall design and construction plus the type and quality of components rather than which direction the driver faces.

    Would placement and room acoustics play some part in the performance of each? If you placed each sub in the exactly the same environment would you expect to get a similar sound given the components and construction are of similar quality? With it being lfe only is it less directional than conventional speakers then. I have never really understood what the pro's and cons of each are and why manufacturers offer both down firing and side firing models :confused:

    I have heard and must say cannot confirm if it is true but people with wooden floors prefer front fireing subs rather than downward.

    I believe that each model of sub will react differently in the same room setting irresepective of whether it is front or down firing due to other parameters in the design such as position and size of port.

    An example would be the SVS range which includes both cylinder and box subs and utilize the same drivers and amps in each. The traditional box shaped subs are downward firing but rear ported so will perform better placed further away from the walls than the cylindrical shaped subs which has ports facing upwards.

    That's pretty much it, the driver orientation is just another aspect of how it loads the room. As has been mentioned, room construction can play a major part (eg. suspended floor or concrete foundations etc).

    Although a different driver orientation probably will change the frequency response in a given room, it's unlikely to change the quality or "amount" of bass that's generated by it.

    Thank you again for the replys, I suppose it would have something to do with looks, if you want to see a grill then get forward firing if not down firing
    BTW I have laminated floor

    I'm having my front facing XLS200 changed to a downwards facing version. It was back in for repair due because it'd started to hum :oops: Lets hope the DF is just as good as the forward facing version :D

    I'll let you what its like as soon as it arrives back. Tom if you're reading this HURRY UP!

    Just to confuse you further it won't be that relevant whether coastersteve hears a difference or not as subs will interact with each different room in a different manner.

    I used to suspect that forward firing subs would work better on suspended wooden floors. But since replacing my 2 KEF45B subs (forward firing) with an SVS PC Ultra (down firing) I've been convinced otherwise.

    My cinema is in an attic and has a suspended wooden floor.
    I was worried at first when I ordered the PC Ultra, but I took a chance.... and it paid off, big time! It works brilliantly.

    As others have said, there are many influencing factors that determine how one particular sub will work in your room. Down or forward firing is just one of these factors, and you'd do better to focus your attention more on the overall quality and performance of the sub.

    Any update on this lads....?
    http://www.bkelec.com/new/Special_Offers/sp10.htm

    I'm seriously considering BK... and not sure of downward of forward firing version.
    I will have laminate floor, and the sub will be placed near the rear wall, next to the side of my sofa.

    Tom @ BK says its makes no real difference.
    If you've got no loose floorboards, then it doesn't matter....

    he would PREFER the downward one himself, if he HAD to choose!
    and that is PURELY on aesthetics.

    Look forward to your review CoasterSteve!

    If you have carpets, should you avoid downward firing?

    I have had a couple of downfiring REL Storms that fired into the carpet and I had no problems at all with them.

    Ok, its setup and working!! VERY quick review.

    The downward facing is definatly more wife friendly. I had the original black XLS and the missus was not 100% keen on it but put up with it :) but this she loves cos it matches everything else.

    Sound

    At first the DF sounded a little more "boomy" if that makes sense, didn't seem as musical as the FF but turning down the gain integrated a lot better. Its still early days to say which is better as I've yet to watch a film on it.

    I'll report more findings later when I've watched a film

    So its a winner ... though is it better than the FF?
    Did you get black again or one of the other colours?

    I will be getting the DF one... when I get round to getting an AMP and DVD player!!
    (just looked at my finances!! :eek: .)

    I went from a Black Forward Facing to an Oak Downward facing. At the time BK didn't do ash in the FF version.

    The misses definatly likes the Oak one better - A RESULT!!! :D

    Sounds good, any sound differences are almost certainly down to the finish on the sub. Black ones go fasta :D

    [thinking mode]Ponders if adding go-fasta stripes to his sub would improve performance...[/thinking mode]
