    I have a Kef 20b subwoofer, i've looked on the Kef site for it's specifications and amongst other things it says

    LF corner _6dB 36Hz - what does this mean?

    Also I got the series 2 version with 100 watts instead of the 70 watt version, is that likely to make any difference?

    What's the opinion on this sub, I paid £200 brand new.

    I understand the LF corner to mean the usable freqency response you're likely to get in your room i.e. your sub should be dropping down to around mid 30s Hz. KEF have been known to understate their figures a bit so you might find that in practice it actually drops a little lower.

    There is nothing on KEFs website about a series 2 version - the bigger model (30B) has 100 watts but there is nothing about a 100 watt version of the 20B.

    Haven't heard one myself but, from what I can gather, it's not a bad little sub and £200 for a brand new one sounds like a a very good deal as the original r.r.p. was something like £350.

    Thanks Matt F,

    There are no details for the series 2 on the Kef website, but I did speak to their technical support who said that the series 2 was made when they couldn't get hold of 70 watt amplifiers.

    It is good ,but I don't have much to compare it with, it would be useful to hear from people who know this sub to get an idea of it's quality.

    You could have a look at the reviews on www.audioreview.com - mainly reviews from owners in the USA but should give you a fair idea.

    Just a few caveats for audioreview though:

    1. Some reviewers give products 5/5 just because they own them.
    2. Some give 1/5 because their product went wrong
    3. Some give 1/5 because they compared the product with another costing 3 times as much which (surprise, surprise) was much better!
    4. There appear to be some completely mad people on there.

    So, check it out but try to weed out the unbalanced opinions.

    Matt.

    They're not mad as in "dangerous" :mad: , just mad as in "take their comments with a large pinch of salt" :clown: .

    I did look on the Audio review site but here are only 6 reviews for the Kef - and most of these are moans about the sub not working.

    So if anyone has any more info I would be interested.

    Would I get a worthwhile upgrade in sound if I went for a Rel 150E bareing in mind the Kef cost £200 and the Rel will likely cost £450.

    Is it going to transform my listening or just be a little bit better for most movies?
