Ivan,
You deal with the modules all the time, and I will defer to your knowledge, but I thought the Speakerpower modules could be set by the end user with a PC interface...however, the process is somewhat cumbersome, and must be done when the module is "out of box" and cannot be programmed on the fly like a Crown I-tech. I believe Simon Coffin, who occasionally posts here and built some self-powered coax monitors with the Speakerpower modules, could chime in on this. Or Brian Oppergaard, who actually builds 'em.
Also, looking at the Digmoda model previously mentioned...it looks like a re-badged Speakerpower module.
