I think you should bring your DR250 speakers to GPAF. That way you can listen to them side-by-side with speakers having compression horn tweeters and other driver configurations. We measured your speakers at the Prosound Shootout, but never really had a change to listen to them. So I think everyone would be interested in having a listening taste test.I'm familiar with two-way setups like that with piezo tweeters. I made speakers with them for 25 years before Motorola and CTS stopped making them. So I know they can be used in good quality setups when used within their limits. I also know what compression horns have to offer. I think you'll be interested to hear a side-by-side comparison as would many others.
