I'll send plans.

The box is the same and the woofer circuit is the same. The tweeter hole cutout is a little different and the tweeter circuit is different. Just cut a hole to fit the tweeter in, basically the same size as the one in the current plans minus the "ears" for the hookup wires. The piezo tweeter is hooked straight across the input terminals and runs "wide open".

Later when you want to upgrade, just swap out the tweeters. Those old models with the piezos are near and dear to my heart, sounding very good for the money. At the time I designed them, there was no soft dome option with sensitivity anywhere close. But now that there is, you can get a much more refined sound. So when you can, spring for the upgrade tweeters.
