Hi Warmon and welcome to the Shack! Glad you found us...
I know someone is using the Tang Bang drivers in a DIY speaker project, but I'm not sure about any sub projects going on. I believe one of our members is building a push push design using larger drivers. You might check out
his thread to get some ideas on a similar design.
We would certainly love to follow your progress and pictures as you build. If you need any images hosted for posting in threads, we can host those in our
Image Gallery for you - it's free!
