I see that you are still working on your DIY project. Have you been able to find the appropriate crossover application for these systems? Are you still using the Rane crossover for your speakers? I made an inquiry relative to your project 7 months ago, but no one on the site seemed interested in my question. I really don't know where else to go to find the specific information needed to finish my little speaker project. I hope you have better luck than I have getting information about these horns.
