No issue with single driver, MT, etc. on the WR125 designs--all glowing reports. The line array designs with the WR125's were early models just after availability of the drivers and thus had not apparently reached enough design maturity, I suspect. Again, I'm reporting what I read on the web and not personal listening experiences.

On the Fountek 2.0 version it offers inherent length and minimzes the gaps which would result if you used Neo 3's in a line.
