Some response and impedance graphs would be invaluable for this driver. Could somebody please supply some?
Hi, I'm planning to make a large sealed cab with these, using your Goldwood GT-25 4" cone tweeters to cover up the top. Do you have any suggestion or recommendation on what frequency I should cross them over?
You could cross the tweeter over just about anywhere between 2kHz and 16kHz. If you want to use it as a super tweeter I would cross it somewhere around 10k.

I'm trying to make a portable speaker with 2 of these drivers. I'm would like relatively good bass responce so what is the smallest ported box size I could use and how big should the port be?
The smallest volume I would recommend is 1.6 cubic feet, with two ports that are 2-1/2" in diameter and 1-1/4" long for a tuning frequency of 65 Hz.
