Hi vishnupg,

You are providing no help as to your application, enclosure size, room size, placement, etc.

Anyway, to get things started: Hornresp is a free design software that you might find helpfull:
Hornresp
After downloading and installing, please, read through the help file, it is quite informative.

The speaker you are referencing does not look like much of a subwoofer, and I would recommend you measure the T/S parameters yourself (in addition to what you have in the specification sheet) before you spend a lot of time on designing, or cutting wood:

Hi GM,

Good news!
I plugged your numbers into my previously submitted simulation and found the measured T/S to be slightly improving the suggestion despite the new driver Sd is larger than the advertised..

The driver would still fit the enclosure with CSA= 224cm^2 as long as the internal width is close to 21 cm.

:cool:

The driver is good one for the price right??

Who knows the price but you? :rolleyes: You're the one who suggested a driver from India. Mail the driver manufactures and post to this thread.
