    Hi Guys

    I need some advice, will I need a sub with the following set up and if so how big and how low should I look at?

    KEF Q30s f/ l&r
    KEF 70S r/ l&r
    KEF Q95C centre

    Marantz 4200 amp

    I have seen some PSW2000's from people upgrading their KEF eggs and I would like to keep the continuity of having a KEF sub.

    Here is the spec on my fronts

    Frequency response 45Hz-20kHz ± 3dB
    Sensitivity 88dB, 2.83v at 1m
    Amplifier requirements 10 - 150w
    Impedance 6ohms
    Net weight 11.0kg/24.3lbs.
    Dimensions (H x W X D) 800 x 190 x 273mm, 31.5 x 7.5 x 10.7in.

    and here is the spec on the PSW2000

    Model PSW 2000
    Design Bass reflex, downward firing
    Drive unit LF: 210 mm (8")
    Frequency response at 15°
    horizontally off axis ±3 dB 35 Hz - 150 Hz
    LF Corner -6 dB 33 Hz
    Amplifier requirements 250 W built in
    Sensitivity (2.83V/1m) Active system
    Maximum output 106 dB
    Impedance Active system
    Weight 14 kg (30.9 lbs)
    Dimensions
    (H x W x D) 370 x 320 x 320 mm
    14.5 x 12.6 x 12.6 in.
    Finishes Video Grey

    Really what I am asking is what the difference is between that bottom limit of 45Hz on the fronts and the 35Hz on the sub.

    Also would I need to turn the fronts to the small setting if I got a sub?

    Cheers

    Matt

    I don't know much about KEF speakers but from what you have posted a sub is definately needed if you want to listen to action films in all their glory as you will be missing the LFE punch.

    From the spec that you have published of the KEF sub, that will not do it for you as that is not a sub to add punch to movies but rather one to fill in the lower end along with satellites.

    You don't need a sub from the same manufacturer as there are no voice coil matching problems but there are some bargains to be had in the classified forums

    Thanks for the advice Ian

    I don't really have much to spend, what are the sort of specs I should be looking for for a sub to add LFE and whats the minimum I'm going to need to spend.

    Cheers

    You can get a good sub for £200 in the classifieds if you're patient and maybe a bit less than that with some of the Paradigms that come up. Unfortunately they are like buses with none appearing for ages then loads all at once.

    Thanks, I saw a Q50 just go on the classifieds, is that the sort of thing that would be best?

    Personally I'd go for something like a REL Storm if you can get one cheap enough.

    You may be able to pick one up for £220-£250 (but you'll also seem them go for more too)...and it really is a stunning piece of kit at that price.

    The Q50 is a good sub also.

    Thanks

    I'll keep my eyes open for a REL, at the moment I think I will have to stick with the Q30s running the bass the outlay is just too much at the moment as I am just setting up and have spent a bomb (in my world) already.

    Its become apparent to me that its worth waiting for the kit you want rather than diving in and getting what to can, I have a Q95C comming for my centre and now I find myself thinking maybe I should have held out for a 100C instead, oh well I suspect I am catching upgraditis before I even have my first complete setup

    Thanks again for you advice, I love this forum, quick and educated advice.

    Cheers

    Matt

    It's worth doing a search for the REL Storm on the forums. Aside from finding out alot of info on them, you'll also come across some of the old for sale threads in the classifieds - this should give you an idea of prices.

    It's probably worth adding that, if buying new, the Velodyne's VX-10 at £200 and CHT10 at £325 take a lot of beating.

    It it was me I'd wait 'til I had £325 and go for the CHT10 but I'd also keep an eye on the second hand market for an REL Q50, Q100 or an ST series if the price was right.

    Got the KEF PSW2000 on a completely crazy budget of £100 and been extremely happy with it. If you can pick one up for less than a ton than I would recommend you go for it, and going down to 35Hz is the best you'd get for that price. It's got a nice glass top and is easy to add to most systems, when I get more $ will get something more serious, but like I say - happy with it for the price. And I would keep the fronts still set too large, as I have, and set the cross over to minimum.
