Hi,
Rahul Am sorry to say but its of absolutely no use

!! else I would've suggested you long time back !!
Dayton Dome Unit
Take a look at the above ( on which you've asked the question ),there tonnes of problems with that,to begin with its Aluminium and you need fabric or silk ! then there's the issue of the frame,the one Dayton has will not fit into your Tweeter's Motor Assembly so.....,then there's the issue of voice coil height and such (which is associated with the frame),Finally the biggest negative of them all the price :sad: At the said 20$ Ex shipping its almost or as much as a brand new tweeter,add shipping to that and it makes things even more unattractive

!
If you want to take my advice,forget importing and all its of no use and you'll never be able to get something exactly the same and in the budget

!
Regards.
