I haven't heard this design from Rick. I did spend several days last year at the 2005 Rocky Mountain Audiofest listening to his similar line array design that uses 8 Vifa XT18 woofers paired with a line of 8 Fountek Neo2.0 ribbon tweeters. I suspect that this design with the lower cost RS drivers coupled with the same Founteks will sound very good as well. It should be a very impressive set of speakers at a reasonably cost as are all of Rick's designs.
