Default finding out specifications

How do I find out the specifications of a subwoofer when it only comes with basically nothing?

You can measure Thiele-Small parameters yourself.

You can find the T/S parameters by useing a proper software and a good microphone connected to your soundcard.Although this is not so simple i think it's worth spending some time.I havent yet deal with it so i can't tell you detailes haw to do this if you want.I am planing to learn more when i find the free time.

You don't need a mic to measure Thiele-Small parameters.

No Theile-Small parameters do not require a mic at all. However, a mic can be useful for measuring other stuff

Yes that's exactly the sort of tests I'm on about. Now if you can show me where it uses a mic on that page I'll buy you a milkshake

hi simon5, do you know if the corrected, T/S Paramaters for the Atlas 12 have been posted any where? i'd sure like to know what they are if so as i'm wanting to build a new vented enclosure for mine but, i can't seem to find any sites where they have been remeasured. parts express has a tester but, they are a little out of my price range. crippledchicken
