    Hi
    Bit of a newbie where decent speakers are concerned. Just what do the 2 numbers mean?

    Current speakers front/rear say 45-20000hz, center 80-20000hz

    Considering a set which says front/rear 120hz- 20000, centre 80-20000

    Just what is considered the best combo

    TIA

    the first number is lower response which means the speakers can reach down to 45hz the second is highest it can reach most are around 20hz unless they have a specail tweeter. if the speaker your considering has a lower response of 120hz it must be very small and couldnt do any bass without the help of a subwoofr.

    Thanks for the prompt reply.

    I am also looking at the SA-VS300H by Sony.

    The range quoted is 24 - 70,000. Would that be considered good?

    speaker Manufactures specs arnt allways reliable although the speaker may be able to produce 24hz but it wont be clean output. U cant really go on freqency responce specs alone get a demo to decide. an exsample the sony might output 30hz at 60db and another speaker at 85db but the specs dont tell u the output.

    Unfortunately the frequency range specs are absolutely meaningless as all they tell you is that the speaker is capable of reaching as low as 24Hz and as high as 70Khz (a mistake I think) but the output could be so low at 24Hz that you can't actually hear it and it is possibly distortion that you are listening to anyway and not pure sound.

    Just to complicate it further the speaker may be badly designed and built with el cheapo components so that although it can reproduce sounds between 24Hz and 20Khz it will still sound like crap.

    The only test instruments worth anything at all are the two protruding ones either side of your head and they will tell you what every statistic under the sun can't and that is whether what you are hearing is worth buying or not.

    Some of the best speakers have terrible specs (Quad ELS's) yet can sound fantastic. As IanJ says, the only real measuring tool is your ears and preferably in your room

    This is a quite common ploy by Sony.

    They are quoting the frequency range of the system not the individual speakers.

    Therefore, the 24Hz is from the sub-woofer and the 70K is from the tweeters.

    I expect the Centre and Satellites go down to 120Hz - which is leaving the Sub-Woofer to do a lot of work.

    If you are expecting to listen to music as well as Home Cinema I reckon you would be disappointed.

    Cheers,

    Nigel
