    Hi,

    Thanks in advance to anyone who helps resolve my query.

    Have finally decided to bite the bullet and buy one of the above mentioned subs.....but which is the one to buy?

    I currently have canton cd100+cd50+cd10 plus an old borrowed paradigm sub.

    Is the only difference between the above subs df- ff that the df speaker is protected from little fingers...(2 year old).

    Will the sub be quick enough, the cones on the cantons are aluminium.

    My budget is £300 and the size has to be compact.


    Cheers :thumbsup:

    As the manufacturers themselves will admit the difference between the two is cosmetic. The BK sub is certainly nimble enough to keep up with fairly demanding speakers and should have no trouble with the Cantons.

    thanks ian for your prompt - informative reply.
    You've helped make my mind up...reading this forum is great but you can end up tying yourself in knots, information overload.



    I just wish I could have stretched to a svs but maybe next time.......jesus, I'm talking about upgrading and I've not even got it yet...

    Thanks again

    I have a BK200DF sub and I am very pleased with it. The performance from such a small unit is amazing.
    I went for the DF model because I prefer it aesthetically and also, having young children, any temptation for them to poke their finger into the cone of the forward firing model was removed.

    Don't forget that the FF model comes with a speaker grill. :D

    My preference is FF for a black or silver finish and DF for the wood veneers but that's just my own taste. :)

    I have the FF in cherry and it looks very nice. DF looks nice too but I was slightly concerned about it firing down into carpet, I probably would have ended up making/buying some sort of plinth....PJ :)

    I'm awaiting delivery of a DF too. Anybody got any model specific setup tips?

    me too - just ordered the DF. I spoke with them, and they said absolutely no sound difference whatsoever

    There aren't any really, just follow the usual guidelines and you'll be going in no time. :)

    PJ, I also was wondering about the sub firing into the carpet.
    Though I did read somewhere else on these forums that someone said a plinth made little or no difference with regards to this sub.....though I don't know if I believe this.
    I am still going to buy the df though......

    Surprisingly enough the carpet isn't really an issue for downfiring subs for technical reasons to do with the wavelength of a bass note that I have long forgotten and as many thousands of REL Strata and Storm owners amongst others will testify.

    As Ian says the wavelengths are so long that they have no idea what surface they are firing at.

    Except! :eek: The DF might shoot any passing housemites into orbit! :D

    I'd suggest you choose your type of sub FF or DF purely on the basis of whether you have kids with curious fingers. If not and you like to watch a bass cone doing its thing then choose accordingly.

    I have the DF. It used to fill a large room (9m x 5m) quite nicely, possibly helped by a concrete floor and not very deep pile carpet.

    I moved house to one with suspended wood floorboards and much deeper pile carpet and found myself with noticeable 'boom or bust' around the 6m x 4m room.

    I found (psychosomatically or otherwise) that the performance improved greatly by putting it on a marble slab - an old pastry board - and putting this on top of some hemispherical acoustic dampening pods (cut up squash balls). The extent to which I have had to turn the XLS DOWN to not swamp the other speakers for movies and music is astounding. The dial is now set between 7 and 8 o'clock.

    Incidentally, I bought the DF model to minimise interference from inquisitive young fingers but find that they (or their friends') are quite fascinated by all the dials on the control panel, even despite (or perhaps because) they are hidden around the back. Mind you, putting Incredibles on without checking where the volume dial is set soon puts everyone in their place, promising not to do it again!

    Have just ordered the sub online (Thursday morning), though I have of yet received no confirmation of purchase.
    Is this normal?
    Did they contact any of you straight away?
    How long did you have to wait?
    All help appreciated.

    From memory I don't think they did ring me but I think I got an email with a parcel tracking no. I remember ringing them just to confirm all was OK and they seemed very helpful.

    I think delivery times depend on whether they have stock or a backlog for your particular combination. I got mine in 3 days (FF cherry) but I suspect something like the DF oak may be more popular and take slightly longer. Worth the wait though. A cool sub!...PJ :)

    on a side note, theo (or anyone else) though the marble board makes a difference I don't know if it would pass SWMBO, though I might be able to cut a small steel plate and attach spikes to it then sit the sub on top of the plate using its rubber feet.
    The steel plate would be more compact, heavier which would make it more stable.

    ....what does anyone think sound wise?

    I really have no idea and have never heard of anyone trying it.




    P.S. it would be a small plate not one you could use to stop anti tank missiles, lol....

    I wouldn't use a steel plate as there's a good chance that it will ring at subwoofer frequencies.

    I don't recall receiving any form of order or despatch confirmation but my units arrived within days. You can always ring them to check if you're worried. :)

    Ordered the DF version, no kids yet with prying fingers but hoping for some :D

    Very good service from them, very well packaged, sounds awesome and mine is on carpet. If I remember delivery was around 2 weeks. Emailed and always got a reply.

    I don't suppose anyone has a few pictures of their bk sub, there are pictures around on this forum but most are average quailty, or does anyone know of a link.
    Trying to get a feel for the size and quality.

    Podium73 - my marble board was actually offered to my by SWMBO. It's about as wide as the BK and only about 4 inches longer and 1/4in thick. The spare inches effectively tuck out of sight behind the sub so it all looks quite neat. I think it's probably somewhat higher on the WAF list than a slab of granite from the builders' yard which was the alternative!

    Granite, marble or whatever can all be covered in a more room friendly textile if that makes it easier to sell to the wife

    cheers eviljohn, had already seen and read the sub test shots.
    The pics for your sub are great it seems to ooze quality for the money.
    Soon as I receive mine I will post some pictures.

    It certainly oozes quality, can't wait to see your pics and hear your own experiences. It's always nice to hear new people being pleasantly surprised. :)

    I ordered a DF last Monday by phone, Tom and Olive at BK couldn't have been more helpful, they even offered to finish it in Rega Cherry to match my speakers :thumbsup: so (hopefully) it should be here any day now !
    I also went for the downfirer as we have a new bambino :)
