    As I said in an earlier post I want to buy a sony minisystem but it's only 200 watts compared to my current 300 watt system but the sony has 6 inch woofers and mine has 5 inch woofers.

    Will the sony system have a much lower volume than my JVC or will it be about the same since they have larger woofers?

    And would adding a 100 watt sub to the sony make it louder than my old system?

    Thanks

    Normally Mini systems are frowned upon..... the question of power ratings is pointless for a mini system since they are artificially infalted so untrustworthy. Volume is not a function of power anyhow. You cannot in any way predict the volume of a given minisystem so dont even try!

    You'll probably end up with less woof per inch with the sony system.

    Volume is directly proportional to the power output divided by the woofer inches. :p

    no it isnt.
    Imagine two 12inch woofers A and B
    Both woofers are 'near' identical, except:
    woofer A has a sensitivity of 86 Dba
    woofer B has a sensitivity of 93 Dba

    Woofer B would be louder at any given power level.

    A crude example, but it still aplies. The fact is, Volume is not directly proportional to the power output divided by the woofer inches, Because there are too many other variables to consider. Sensitivity being a very important one as far as this arguemnt goes.

    also i totally agree with buns. wattage rating in systems of that callibre are extreamly inflated and can never be trusted.
    I would personally try to listen to both systems before i made the decision, or otherwise find reviews of them to compare the two.

    Confused?

    The reason for this is obscure, that's why the higher the fewer.

    Well observed!!

    James, I completely agree with you on the sensitivity issue. I believe that as it is measured in db it is a logarithmic scale. i.e. 100db is not twice as loud as 50db, it will in fact be more than twice as loud.

    it is in fact closer to 24 times louder (an increase of 10db is viewed as being twices as loud - so 60db is twice as loud as 50db, 70db is twice as loud as 60dd and so on)

    lol yeah dont about forget that. you would probably be closer to half their rated power when properly (like 0.1% THD, not 10%!)

    Midi systems are usually quoted as

    Rated Power into 6ohm, 1 Khz tone, DIN xxx W at 10 %THD.

    Compare that with the standard both channels driven into 8 Ohm, full sweep, xxx RMS at 0.05% THD.

    I just looked at the specs and the sony minisystem I got is less than 0.09 THD for the main front speakers.

    You guys kill me. This is one of the most delightfully entertaining threads I've read in a long while, and I don't even know what the frick is going on. It's so Monty Python.

    yeah, but if I'm trying to measure the wattage of an analogue stereo amp do I have to use a slide rule for the logarithmic transform; if so, anyone on these Boards seen any going S/H?

    How bored were you last night Pointon? I love your angry posts and today I find them where ever I go. 'Tiss very funny.

    Look, guys, everyone know that speaker loudness is related to a)how big the cabinets are- the bigger the louder b)how much their prescence ****es your missus off and c) what colour the cones are painted- red= very loud. Sony all ways use red on their loud systems.

    But what about the Watts, are they British standard large or Japanese small. Just like eggs.
