I'm an absolute beginner and want build enclosure for my subwoofer for which i don't know the Ts parameters can any one suggest me how to measure those parameters as near good as possible.
Thank you.
Thank you.
Welcome to the forum!
Have a look at this: https://www.daytonaudio.com/product/1650/dats-v3-computer-based-audio-component-test-system
It costs around £200 in the UK.

If you understand german, search on the net for a little booklet (Francis Verlag 196) written by Professor Panzer: Die Konstruktion von Basslautsprechergehäusen. It is about the construction of bassloudspeaker enclosures with the help of the filtertheorie. Contains a lot of knowledge and, amongst other things, also how to obtain the values of Qes, Qms, Vas. You need a frequency generator and counter, oscilloscope, DMM, some resistors and a unmagnetic known weigth. Needs determination and is qite a lot of work, but you sure will learn something.

By now you may be realising that buying a subwoofer which has published T/S parameters could involve less hassle and possibly less expense than measuring the T/S parameters.
If you are still following your thread please tell us the make and model of the subwoofer you have, as it's unusual for parameters not to be available.

Doing it with REW and a soundcard or audio interface.

Also with LIMP more details on some aspects that also apply to REW

Very similar gear is needed if you are going to test your speaker after it's built.

Precisely!
The outlay to an "absolute beginner" in terms of purchasing equipment of ANY kind just to measure ONE driver may not make good financial sense.
I was going to add that, but left my post as is to give the OP food for thought.
However, he seems to be taking a long time to chew it over!

it is a chinese one "worldtech WT-8051WF/21" . Please share me the parameters if any one have them.
Thanks man but my driver didn't cost that much. Have to find other ways.
Sheesh! When you posted 'unknown', you weren't kidding! Please publish them once done. TIA
