I haven't heard of them either. Apparently, the company is better known for its bass cabinets. It went bust at some point of time and left users and orders high and dry. But now, they seem to have made a comeback.
2 tweeters?? 
2 tweeters??
I don't have your knowledge to elaborate on this subject but here is what they say about their concept:
''We absolutely love highs! However, we don't like harsh, nails on the chalkboard, artificial highs. Compression horns were developed for PA Systems where they have to throw the sound far to cover large areas. They were never designed to be used in instrument cabinets. The industry ended up using them for this application because they were readily available, accepted & cheap.
Instead of taking the easy way out & using 1 brittle horn, we slice the upper end into 2 specific areas; the upper mids & the highs. To accomplish this we chose 3 separate natural sounding drivers; a upper midrange & 2 soft dome tweeters. Can you say bliss!''
Those 2 tweeter units were used when there were no tweeters with a high pressure available. But it comes with a lot of issues.
