Good service and fast delivery ... and quite cheap 😉

Also look at this thread

I think that 6 um is a good compromise ... how low do you intend to go?

That is just what I was looking at, I would like to go to 40hz if possible.

If you are going to make larger bass panels (which will be needed to go to 40) you should/could consider using 12 um.
6 um I think is a good compromize for broad band mid to high. For a real tweeter section 3.5/4 or even 2 um would be even better.

(seems my last link to ebay don't work ... cut in half 🙂 )
