Default My 6,5" Westra driver? What can i do with it?

Hi all,

I have a Westra KW160-1374 (in fact a pair of) bass speaker. And i want to make a little subwoofer with it. I will drive it a 50W power amp and of course a sub xover. I also want it in tiny sizes and have a lot of deep bass.

What do you recommend about that project? What kind of box must i use for it?

Thanks a lot for your recommendations..

Qts is quite high, would need a fairly large box for vented use, so I'm afraid tiny size and deep bass are out of the question - you're going to be looking at around 30 litres.

Maybe, maybe not, try it!

There's limits as what you can do with 6.5s.

I'm not good at wood works so will go to a carpenter to make the box! Sure i will try it but i want to have an idea that how it works? Will it be like my Jazz 9940 speaker's subwoofer? What do you think?

or for the sub, you may want to make a bandpass and mount the two drivers like this:

A 6.5 inch driver will never be a sub, no matter how low the graph on WinISD says it will go. This is simply because to get low bass you need to move a lot of air.
